#10 Dumb Things I Would Never Let My Athletes Do, and Which Landed Me in the Hospital

20161004_144809

Good evening, gang. Sorry I’ve been MIA for a while but this truly has been a shit show of a week… and it’s largely my fault.

The rollerderbystrengthcoach did something that she tells her athletes NOT to do all the time, and now she’s paying for it. I pushed too hard while fatigued, ended up losing focus and injured myself in the gym.

I don’t usually train on Mondays. It’s superstitious, but throughout all of my athletic and fitness career I have avoided training on Mondays because that’s when most of my injuries (outside of games) have occurred. By continuing to believe that nonsense I actually think I set myself up psychologically for the injury that I suffered. I would like to blame it solely on Monday, but to do so would ignore my own dumb decisions. Here’s what happened:

Several weeks ago I started a new, fairly intense training protocol to help me get ready for the upcoming 2017 Highland Heavy Athletics season. The first block of the program calls for a lot of volume on all gym training days, which are 5 per week. Now in and of itself, five days a week (even at significant volume) doesn’t usually put me in an overtrained state, however, I’m also practicing my throws 3 to 4 days per week to correct some technical issues that I need to work through to be ready for January , building a business that has me working 12 hours a day most days and rarely sleeping more than 5-6 hours per night. Recipe for bad juju, right? Yep.

For the last few weeks I’ve been lifting on Tuesday, Wednesday, Friday, Saturday and Sunday, and throwing on my three off days. However, because of my work schedule I switched these last few weeks to lift Monday thru Friday and throw on 3 or 4 of those same days… all while being overworked and underslept, something that I know  lot of roller derby skaters can empathize with. Training at this volume under those circumstances was the first of the dumb things I did that led me to have this lovely bracelet on.

I was also physically hurting a bit. My right hip has not been happy with me for about a week (I had to have surgery on the left one last year and the right one is now showing similar problems) but instead of backing off I’ve continued to push through it. That was the second dumb thing I did.

Monday was a squat day. Four sets of power cleans, then on to squats (I should have then done Nordics, eccentric RDL’s, calves and core – I didn’t get that far). For squats my programming called for 3 sets of 10 at 65% (for me that’s 185 right now). Usually I train in much higher percentages for fives, triples and doubles during this part of my training cycle, but since this was what was called for I was ok with doing higher rep, lower volume stuff. Except apparently I wasn’t ok with it, because after I finished the programmed sets I decided that I needed to get some doubles in at 90%…255. This was my third dumb thing.

I’m usually meticulous in my set up, but 255 isn’t super heavy for me on a normal training day and so I let my attention drift out to the idiot 25 year old boys that were benching next to me and saying things like, “that would scare most people” when talking about the 225 that they had racked. (I wanted to ask, “Really? What people?” but kept myself in check.) However, it broke my focus and I KNEW it broke my focus, and I KNEW my hip felt tired on the previous set, but my ego took over and I un-racked the bar anyway. Dumb thing #4.

As I backed off of the pegs, I never checked my feet… I don’t mean by looking down (I don’t do that because it causes a loss of tension) but I didn’t actually feel for the floor underneath them, a critical part of my set up. (Dumb thing #5) As I started the descent I knew that something was wrong, but I didn’t dump the bar. (Dumb thing #6) Instead, knowing that something felt wrong in my hip I started muscling back up out of the hole without using both of my hips completely (Dumb thing #7) which caused my left hip to come up just slightly before my right and making my lower back take the entirety of the load in a hyperlordotic position. I felt the strain and STILL didn’t dump it, I think because I didn’t want to drop it in front of the idiots next to me (who’s the bigger idiot here? Me. Definitely me. Dumb thing #8).

When I re-racked I knew immediately that something was terribly wrong with my lower back. I could barely get on the floor to change my shoes. Picking up my bag to leave the gym was excruciating. I refused to tell the management because I didn’t want them to have to fill out an incident report, so instead I drove myself home in my incredibly bouncy jeep. (Dumb thing #9.) When I got home my husband was home for lunch. If he hadn’t been I never would have made it into the house. He tried to get me to go to the hospital (he had a catastrophic back injury that ended his international rugby career, so he knows well how bad I was hurting) but I refused. (#10)

So here I am, a day later, lying on a gurney in the ER. What finally convinced me to go? The fact that I couldn’t sit down to pee and that my right leg isn’t working great. That and Hurricane Matthew. (We’re likely to get a pretty direct hit here in Florida and since I couldn’t even sit to pee I thought I’d at least better get some pain meds.) As I expected, the ER doctor scolded me. “I knew to stop lifting like that when I hit 40,” he says, looking at my 1973 birthdate on my chart. “You never lifted like that,” said the expression on my face. (I didn’t actually say it… he hadn’t given me the pain meds yet – lol).

Anyway, it looks like I got lucky. The X-rays were inconclusive, but the vertebral spacing is consistent, which is a good sign. It means that this is likely just some torn muscles and a ligament or two, rather than two blown disks. I will decide as the week goes on if I will follow up with an MRI. They gave me percoset, flexeril and prednisone, so at least I’ll be comfortable through the hurricane.

I still can’t sit to pee very well though. I know that’s TMI, but it’s something I bring up because until you have a back injury you never really think about it. I’ve had 6 knee surgeries, one shoulder and one hip and I’ve ALWAYS been able to get to the bathroom without significant distress. This is an entirely different animal. Additionally, this cost me, at minimum, $1000 for the ER visit and the drugs, plus at least two months off from heavy lifting and throwing. It’s also possible that I may miss the first part of my sport season now. All because I did a bunch of dumb shit. Shit that I coach other people NOT to do every single day.

The point of this post is that even a coach sometimes makes really bad judgment calls when it comes to her own training. Given how competitive many of you are I know at my core that some of you out there reading this have pushed too hard under bad circumstances too. If you’ve been injured, then maybe you’ve learned the lesson better than I have. If you haven’t been injured yet, I’m writing this for you…

I couldn’t decide if I was going to tell all of you this because it may give you pause to take lifting advice from someone who just fucked herself up so badly. But then I realized I had to tell you, because if I can save even one of you from making a similar dumb mistake and pushing too hard when your body tells you enough (due to fatigue, overtraining, poor nutrition, whatever) you should listen.

The fitspo meme “The only workout you regret is the one you didn’t do” is wrong… the only workout you regret is the one that you got hurt doing. Non-contact injuries should never happen in a weight room. Ever. Please be smarter than the coach.

Training Tip Tuesday

Barbell Kneeling Squat

Since I started up the rollerderbystrengthcoach blog, I’ve gotten a lot of emails about what sort of exercises skaters should be doing. It’s a great question, but one with a vast array of answers. What you SHOULD be doing depends on what your goals are, what your current physical condition is like, what your current performance metrics look like, where you are in your season, whether you have any injury or biomechanical/kinesthetic restrictions, etc… in other words, it’s a really difficult question to answer in a vacuum.

There are, however, some movements that can be incorporated into pretty much any players’ arsenal of off-skates exercises. One of my faves is the barbell kneeling squat.

I know it looks a bit silly, and if you’ve ever been in a gym where you’ve seen this done you probably associate it with bikini competitors rather than contact sport athletes, but trust me, this is a good one.

Hip extension is, by and large, the most important movement in any sport that requires an athlete to move their entire body or generate power. There are 4 primary muscles involved in hip extension but the largest and most powerful is the gluteus maximus (aka, the glutes). Yep, your butt muscles are the ones we’re targeting here.

zebras-1081445_1280.jpg
Kneeling squats work great for skating refs, too. 

You may be thinking, “but don’t regular squats and lunges work your butt?” If you are then you’re partially right, but the truth is regular squats and lunges produce far less activity in the muscle fibers that make up the glutes than this exercise does, regardless of the type or depth of the squat or lunge. In fact, the only category of exercise that elicits MORE peak butt-muscle-fiber activity are those that allow for hip hyperextension, like hip thrusts and glute bridges.

Now you’re probably thinking, “why don’t we just do hip thrusts and glute bridges then?” Well, we do. Lots of them. We do squats of all different varieties as well. But here’s the snazzy thing about kneeling squats that makes them worthwhile… the position in a kneeling squat severely disadvantages your hamstrings and prevents them from taking over for your glutes, a problem that lots of people, particularly beginners, have when doing hyperextension-type exercises like hip thrusts. Plus, because you have to stabilize the bar by keeping your core tight and your thoracic spine stiff throughout the movement, you’re getting a hell of a lot of workout with just this one simple exercise.

It looks weird, but a few cheeky stares in the gym are worth the results, I promise. (See what I did there?) Anyway, it’s time to get your butt to the gym and give it a try.

“Agility ladders” don’t make you more agile… and they don’t make you faster, either.

Agility Basics

Agility Rule #1: In sports requiring maneuverability your center of mass cannot remain stationary.

We’ve all seen them on Facebook, Instagram or any number of blogs across the interwebs… video clips of athletes doing all sorts of fancy footwork running through a stationary ladder lying on the ground with a caption that reads something like “Getting my agility training in today.”

No, my friend. No you aren’t.

Agility is the ability to explosively move to change direction and position of the body quickly and effectively while under control in reaction to external environmental stimuli on the field of play(1). (Notice that some of the words in that previous sentence are bold, in italics AND underlined? That means they’re really important.) Agility therefore requires that the center of mass (the body) be displaced and that the displacement occurs due to an athlete reacting to some external factor such as an opponent or the change in the travel path of a ball/puck/shuttlecock(2), etc.

One of my favorite visual representations of this definition comes from the world of rugby. Quade Cooper(3), who plays for the Australian national side, has one one the best lateral steps in all of sports(4). Check him out as he makes Cory Jane of the All Blacks look just a bit silly:

Notice what he did? He took a big step, planted hard, and reversed direction. There were no mincy, choppy quick-steps, and it was his body that changed direction, not his feet. That movement pattern is the same no matter what the sport(5):

And guess what? It’s the same movement pattern on skates as well(6):

None of those movement patterns look anything like this, and for good reason:

If the people in the first three videos did what the guy in the last one is doing they would get crushed by a tackler, blown past by a ball that sailed out of reach or blocked back into the pack and brought to a dead halt. He would get beaten because his center of mass never moves. And while this guy isn’t exactly the most talented or graceful ladder runner, the movement pattern is the same no matter who is in the ladder. All motion is happening below the center of mass and that means this movement doesn’t meet the definition of agility. In short, ladder drills are simply not effective at training ANY of the skills necessary to be agile(7).


If you want to become more agile, ditch the ladder and let’s talk a bit about things you can work on to help with your agility. The first is strength, and that brings us to:

Agility Rule #2: In order to explosively displace your center of mass, you must be strong enough to overcome both gravity and inertia.

“Strong enough” is a relative phrase. Just because someone can deadlift 500 pounds doesn’t mean that they will be able to stop on a dime to avoid a sweep blocker or make a sharp lateral cut to catch a jammer as she tries to slide past on the inside line. The strength that I’m referring to here is more elastic in nature. It deals primarily with your legs and your core. Your leg muscles must have the strength to decelerate your body mass efficiently, the strength to make the moment between deceleration and re-acceleration as short as possible, and the strength to efficiently propel you in the other direction. Your core strength is even more important in determining the rate of direction change, particularly with respect to your trunk stabilizers which have maintain static tension as you go through the motion.

Great. So what the hell does all of that mean?

Since, in my opinion, core stability is the most important feature of strength as it applies to agility we’ll start there. I’m going to assume that everyone reading this knows how to do a plank. Good. Unfortunately they just aren’t very useful when it comes to athletics. Unlike the static motion of a plank, when playing sports at least a portion of your body is moving at all times. You also (hopefully) don’t spend much time in a prone position staring at the floor. Instead, what we’re looking for are exercises that help your core musculature do what it needs to while you skate: stay stable to transfer force between your shoulders and your hips as they move, and produce force by contributing to hip flexion and rotation.

The list of exercises that can help improve these functions is vast, but here are a few examples of ones that I use with my clients(8):

Wide Stance Anti-Rotational Chop:

Banded half-kneeling Pallof press:

Landmine rainbows (works both lateral anti-flexion and anti-rotation):

Rotational medicine ball toss variations:

Those should give you some stuff to start working with. Although I mentioned leg strength above, we’re going to deal with that in a future post because it’s quite a bit more involved and deals with multiple joint angle training, working with various types of muscle contraction, ground reaction time and mobility.

Now, let’s say you’ve been training for quite some time and have all the strength of Hercules, with legs as powerful as pistons and your core as stable as a tree trunk… you are ready to unleash your fury against your opponent, right? Nope. There’s still more to it.

Agility Rule #3: Physics and biomechanics matter.

All the strength and power in the world won’t matter if you can’t apply the force you’re generating into the ground at the proper angle. That’s because no matter how awesome you are, you can’t defy physics. To move in a particular direction you must apply force in the opposite direction of the way you plan to go and the more force you apply to the ground, the more the ground will push back at you.

Maximum force application to change directions therefore requires an athlete to utilize certain angles, and the ones we’re primarily concerned with in roller derby are shin angles. There are two types of shin angles, positive and negative. This is what they look like(9):

shinangle2

What we’re looking at is the angle between the shin and the foot. If it’s acute then it’s a positive shin angle, if it’s 90 degrees or obtuse then it’s negative. When you are doing linear acceleration and deceleration (in a straight line) off skates your shin angles should be positive on the acceleration and negative on the deceleration to allow you to put as much force into the ground as possible. However, when on skates the mechanics of linear deceleration are obviously different because you can’t utilize negative shin angles unless you spin backwards and dig in with your toe stops. This is why using lateral deceleration dreamstime_l_67127902(variations of hockey stops and power slides) is usually the best option for derby players to stop quickly from high speeds(10). When you’re doing lateral acceleration and deceleration your shin angles should be positive during both actions because it allows you to generate maximum force to overcome both momentum and gravity.  This is why a jammer dancing on her toe stops to try to move laterally around a wall of blockers once they have her hemmed in rarely succeeds. By going up on her toe stops she creates a negative shin angle which automatically tells her brain that she is in deceleration mode, limits the activation of calf and quad muscles and prevents her from putting enough force into the ground to move sideways efficiently(11).

Here’s a fun example of what good shin angles can bring to the table in lateral movements:

While his body position relative to the ground is what most
people immediately notice, what I’m actually looking at are his shin angles on the shin angleinside foot. It’s tough to see in the video because he’s moving so quickly, so I tried to capture a still shot so it’s more easily visible. Look at his left leg (on the right to us) and the angle between his shin and top of his foot. Pretty damn tight, even with his heel up. (He’s also getting some really good drive because he’s coming in so low to the ground, however, that’s not very useful from a sport perspective because there are virtually no moments during a game that an athlete would find themselves in this position.)

Like the strength training exercises discussed above, there are tons of different drills you can do to help improve your ability to keep a positive shin angle. Most of them are designed to increase linear acceleration rather than lateral, but the shin angle mechanics are the same.

Push-Up Starts(12)

Mountain climbers into sprints(13):

Once you have the idea of positive shin angle down, you can include it in your lateral drills, which I’ll show you some examples of in the next section.

So now you’ve got the Herculean strength to unleash on the track, along with Sir Isaac Newton’s grasp of physics… that means you’re ready to go embarrass your opponents, right? Still not quite yet. Remember that there were some words in bold in the definition of agility? The stuff above covers the body part of the definition, but we still have to deal with this bit: in reaction to external environmental stimuli.

Agility Rule #4: No matter how much body control you have you’ll still get hit in the face if your brain doesn’t react fast enough to the fact that someone threw a punch at you.

This is the part where most “agility” exercises fall apart. Most of the exercises touted as “agility work” would better be called change-of-direction training. This is because whether we’re talking about stationary cone drills, lateral hurdles, plyometrics, etc. they all leave out this one key component. They’re static in nature, so you don’t have to react to anything because you already know what’s coming. In other words, if you aren’t being forced to react to some external change in stimulus then you are not becoming more agile. Think of strength and physics as building blocks. You need them, but they’re not the whole structure. What ultimately matters is your ability to use those attributes to react to external stimulus and reorganize your body accordingly.

That requires a whole different type of training and this is where most of the really fun stuff comes in. We’ll call them Reactive drills. There is virtually no limit to the number of these you could come up with, and I’ve frequently done partner-mirror drills, partner reactive sprints, multi-directional shuffle drills, etc. (both on and off the track). Recently, however, I saw some new ones (or new to me at least) on Matt Dickens’ Pure Health, Pure Sport blog that I really like. Matt is currently the head of physical preparation for the Andorran National Men’s Alpine Ski and Snowboard Cross Teams and he has his guys doing some really cool Reactive training.

The key here is that the athletes have to utilize their hard earned strength as well as as physics while simultaneously reacting to unknown/unexpected/changing external stimulus. And that is exactly what we’re looking for. It’s an added bonus that all of the drills in this video can (and should be) done by derby players both on and off skates.

In Conclusion

Ladder drills don’t work for increasing agility. Period.(14) If all of this is coming as a shock to you and you’ve been using ladders for training, please don’t feel like you’ve been duped. Most of the American football programs in this country still use these silly things and the misinformation about their training effect is right up there with the stuff going around about elevation training masks (hint: those masks don’t actually train you for elevation) so you’ve got a lot of good company. Hopefully, however, the information in this article will help you start training more effectively to help you reach your dreams of track dominance.


1. That definition is my own phrasing, but is similar to what was used by Sheppard and Young (2006), who defined agility as a “rapid whole body movement with change of velocity or direction in response to a stimulus.”

2. A shuttlecock is the thing that badminton players, who are truly some incredible athletes at the world championship level, smash back and forth across the net. I’ve never had the opportunity to use the word shuttlecock in a sentence before and I feel that my life is just a little more complete now that I have (three times). I’m betting that you’ll never forget what’s called and that you’ll whip out that linguistic gem the next time you’re at a family barbecue and someone strings up a net. You’re welcome.

3. Just by way of disclosure, I am a HUGE All Blacks fan (the New Zealand national rugby team that Mr. Cooper is seen out-stepping in that clip) and I also support a team in Super Rugby, the Gallagher Chiefs, that he has caused havoc for over the years. The point is, despite the distress this guy has caused me as a sports fan, I have no choice but to acknowledge his magnificent level of agility.

4. Quade Cooper’s side step of Cory Jane is impressive, but is definitely not unique in the rugby world. If you want to watch some really impressive agility just from the last Super Rugby season point your browser here: https://www.youtube.com/watch?v=woJxp65SyUo .

5. Serena loses that point and ultimately the match (Australian Open 2016 final) to Angelique Kerber. However, her incredible ability to react to the ball and explosively move her entire body from one position to another on the court is one of the things that has made her one of the best athletes of all time.

6. Up until the last few years it’s been really tough to get good clear video of derby games to use as examples of specific movements. Thankfully WFTDA.TV now has excellent production value and a huge video library available on YouTube.  It only took me about ten minutes of reviewing footage from last year’s WFTDA Championships to find that fantastic clip of Rose City’s Scald Eagle doing her thing. The portion of the clip you need to pay attention to is the first part of the replay as she side steps to pass Gotham’s pivot. Note that it’s her torso that shifts as she takes one hard plant step.

7. They also don’t increase your speed, but I’ll save that break down for a later article.

8. The videos in this section came from three of the most well-respected guys in strength and conditioning, Eric Cressey , Nick Tumminello and Bret Contreras .

9. I can’t draw. At all. Not even a stick figure. I learned this when trying to use inkscape to create a diagram for this today. I resorted to theft from http://accoladeathletics.blogspot.com/ . Hopefully they won’t sue me.

10. Because of the mechanical differences created by our equipment, off skates linear deceleration training is of limited use for derby players.

11. A jammer might be able to execute a quick hop sideways off of a toe stop if she already has momentum coming into the pack, but if she’s stopped or doing a slow roll, it’s next to impossible to generate enough power that way to propel you laterally past an opponent. If you don’t believe me, try this: without your skates on get into derby stance and jump straight up as explosively as you can. Now get back into derby position, get up on you tip toes and try the same jump. Unless you’re some sort of alien or a superhero, I’m guessing you only jumped about half as high the second time.

12. Video by: King’s Sport Training.

13. Video by: Joe DeFranco.

14. I’m not saying that they are completely useless, because I do believe for brand new skaters they might increase proprioception (the sense of the relative position of neighboring parts of the body and strength of effort being employed in movement) and help with motor control as newbies are learning to connect their brain to their feet. My colleague and vaunted rugby strength and conditioning coach Keir Wenham-Flatt would probably disagree with me about that, because his distaste for ladder drills is even more deep seated than mine. One of his NSFW posts about the topic is here: http://rugbystrengthcoach.com/agility-ladders-are-bullshit/

Once you’re in, you’re in for life…

My reason for starting this blog is simple… I love to help athletes get better at what they do. I’ve been involved in both fitness and athletic performance coaching for more than a decade, working with and around athletes at every level, from social league amateurs to Olympic level champions. I’ve been involved with roller derby for nearly as long, first as a player and later as a head coach, a league announcer and as a strength and conditioning coach.

Over the past two years I’ve had some amazing opportunities to learn directly from some of the best sport performance coaches in the world, including those who work with the NFL, the NHL, the PGA, Major League Baseball, national level rugby, professional soccer and members of the US Olympic Track and Field team. Throughout all of those incredible experiences I find that my mind always comes back to the same thought… “how could I apply this information, this technique, this coaching cue, this drill, this program design, to roller derby?” I’m hooked for life, no two ways about it.

rollerderby-112223_19202And so this blog is dedicated to all of the women and men of the amazing sport we call roller derby. Whether you are fresh meat or a seasoned vet, play flat or bank track, skate women’s, men’s, junior’s or co-ed, or are in the US or abroad, this space is yours.

Each week we will endeavor to bring you the very latest and best science-based information about athletic performance as it relates to the sport we love. There will be training posts, discussions regarding biomechanics and kinesiology, articles on sports psychology and coaching technique, interviews with some of the best coaches and sports scientists from around the world and guest posts from a whole range of strength and conditioning specialists.

So that’s what this blog is about. It’s about making roller derby players better roller derby players. Sound like something you might be interested in? Make sure to sign up for our newsletter so you don’t miss out on any of this great info.

Citius. Fortius. Altius.
