The dangers of bad coaching

So one of my crew mate’s sister in-law when to a different Crossfit Gym, her first time (there's a guy, it's a story) and the workout was one that I wouldn't even do.

He had his beginner class to 3 rounds with 30 GHD sit ups (with dumb bell thrusters). Even the Crossfit founder Glassman, despite is many faults, only prescribes 5 to 10 reps for beginners and only to parallel, not to the ground.

Well she ended up with severe Rhabdomyolysis, (the breakdown of muscle fibers that leads to the release of muscle fiber contents (myoglobin) into the bloodstream. Myoglobin is harmful to the kidney and often causes kidney damage) like DOMS but too much for local immune response to handle so you kidneys essentially process muscle tissue. Not good.

The coach should know not to prescribe such a workout to beginners. This kind of thing give Crossfit a bad rap when it's the programming of this particular coach that was at fault.

Naturally he is denying all responsibility, claiming the athlete should know their limitations. I was thankful for a friend of mine's resent post on Facebook about Dunning-Kruger effect, which this is clearly the case here.

So if you or anyone you know is thinking of trying Crossfit stay away from Groupon promotions. Go to L'Usine in Gatineau or Physics Crossfit in Orleans or Crossfit 613 in the west end.
