Re: The Functionality of the Sit-Up

Are you guys talking about a sit-up done on the floor (or a mat), and not a GHD? If so, how do you keep your legs, bent or straight? Anchored?

On a floor, legs bent, feet anchored, hands behind the head.

My post at the bottom of the previous page mentioned the GHSU as the same core attitude I tried to maintain while doing the standard SU described above.

Re: The Functionality of the Sit-Up

The maximum for the Navy PRT is 101 (mind you, somebody's holding your feet).

I know I'm bringing back a dead horse, but I just thought about this: In "Naked Warrior," Pavel Tsatsouline recommends tightening the abdomen into a wall around the spine, coordinated with your breathing, when doing any maximal effort to increase strength. This tightening motion is almost exactly the same feeling as a situp (more like a crunch or an L-Sit, really, but isometric without the actual flexion). I have personally found that even butterfly situps on an abmat (which entirely pull your hip flexors out of the equation and slow your situps down pretty dramatically) have some value in simulating and practicing this contraction.

Bingo.

Do them with your legs in the groin stretch position (with arms forward and kept low to remove any momentum) and you'll work your hip flexors in a completely different way, and the use of your core to stabilize up into a good posture sitting position is in my mind (see that part of the sentence about stabilization again) an excellent challenge. Most people I know can do sit-ups well, but have them do that they get this rather odd look as their eyeballs pop out and they don't understand why they can't sit-up anymore. Now is this realistic - maybe not, but it sure works your body in a rather random and different way that has helped me, because I know those hip flexors are working overtime putting deadlifts down and such.

Re: The Functionality of the Sit-Up

If you want to challenge your abdominal (stomach) muscles but spare your spine, try the planks, L-sits, sideplanks and modified curl-ups

Sit-ups but a tremendous amount of undue stress on your spine as they involve spine flexion (especially troublesome for people with a history of back problems).

I agree with all of your post except this, which I never really understood. Why are the hip flexors working to put down a deadlift? Surely the hip flexion in this circumstance is done by gravity, which the hip extensors are working eccentrically to control.
