Crossfit Blackbox TR:
Reserved a spot for 10am saturday, which was probably unwise considering friday night was a reunion of sorts which leads to issues of alcohol and sleep deprivation. Anyway, I woke up, popped some caffeine, a lil protein shake and and went to the midtown spot.
There were three other guys in the class; all seemed reasonably in-shape. Instructor was cool.
Quick summary of the class:
> What is crossfit/why/who does it/ what does it do, etc
> Other promotional stuff
> GPP/Intensity/Power
> 3-sentence nutrition guidelines
Movements (more on these later)
> The squat
> The push up
> Knees-to elbows (on pullup bar)
Workout:
10 mins
5 Knees-to-elbows
10 Pushups
15 Squats
Max rounds.
The movement clinics were pretty nicely done. How NOT to squat was shown. Basic movement dysfunction was addressed (partial reps, knee breaks, hip freeze, knees buckling). Medicine ball was used to "keep you honest."
Learnt something interesting about hip-flexor recruitment during the squat. Apparently this is more relevant with explosive BW squats than with heavy loaded back-squats. The drill was to lie on your back, curl your ankle towards your chest and have someone offer resistance while you recruit your hip flexors to draw the knees to your chest. This is then used to "pull" you into the bottom position in the squat.
Pushups were pretty standard. True form v other random stuff was explained. Shoulders should be "active." Neck should not be tilted forward, nor extended back too far for maximum power production.
We got a "rhabdo" warning, which was pretty interesting. Instructor claimed that crossfit has been known to induce rhabdo in 15 mins.

Another soundbite was on 300 the movie. He said crossfit was used (semi-true?) and no juice. This has been debated.

Definitely a productive saturday morning.
