It is CrossFit's contention that the primary job of the abdominal muscles is trunk stabilization. This statement is enough to make any conventional fitness professional turn their head faster than someone yelling "Free soy and seaweed shakes!" The conventional wisdom says that the job of the abs is primarily trunk flexion. They obviously have never done any overhead squats. But think about it. Other than sitting up in bed, or some similar motion, how many times in a day do you actually flex your trunk where ONLY the abs are flexing, especially under any kind of load? Conversely, every time you sit down, stand up, pick something up, twist, reach for something, etc., your trunk has to be stabilized. The abs, obliques, and lower back muscles are always at work.
We do, occasionally, do some hip flexion exercises in CrossFit, but it's always combining the abs with the hip flexors, which is how they're used in real life. We don't specialize in anything, except not specializing. Our body parts were created to work together, not independently. That's why no individual muscle can produce as much force as many together. Here's something to flex and stabilze you for the weekend:
Workout of the Day
3 rounds for time of:
run 400m
15 GHD Sit-ups
15 Overhead Squats (guys 95#, girls 65#)
Check out the demos from CrossFit if you don't know how or what to do. If you can't do GHD situps, then: 1)you should join us at TCF where you can, and 2)you can sub 50 sit-ups per round. Scale the OHS weight as needed. 3,2,1...GO!
If you're still wondering whether you should join us or not, we're wondering why you wouldn't! Here's a little article someone made me aware of recently on MSN that might help you out.
