Im not joking! Other than stabilization the rectus abdominis does not contract! The action of the rectus abdominis is trunk flexion. Hanging leg raises works the hip flexors.

Wow you couldn't be more wrong. The *purpose* of the abs is not flexion, it's stabilisation. Your spine, with no support from your core, is about as strong as a cooked spagetti noodle. So what keeps your spine from snapping like a twig under big loads, like 400 lb squat or deadlift? Your core.

Now, try and do a flexion exercise with 400 lb loading, and I guarantee you'll leave the gym on a stretcher. In other words, ab exercises that cause spinal flexion, like crunches, are useless. If you want a strong core you need to do exercises that are isometric on the core, like hanging leg raises, ab wheel rollouts. and of course heavy deadlifts, squats, and overhead presses.

If you think I'm wrong that's fine, you go ahead and think that while I lift something heavy.

Ok, you want me to snap a pic of the action of the rectus abdominis straight out of my kinesiology book?

And if you read what i said my first post said other than stabilization the rectus abdominis does not contract. It contract isometricly to helps stabilize. The act of doing a straight leg raise, is hip flexion which the hip flexors are utilized.
 
The best part about this discussion is that it all started from a men's fitness article

Your anatomy needs work. You are incorrect. Keep reading.

Here, I'm feeling generous today.
Invalid Link Removed

Also, when the insertion pulls towards the orgin, this is a contraction.
Think about it...

Yes, i know all the insertion stuff dude. The rectus abdominis does NOT even insert on the femur . So please tell me how it assist hip flexion other than stabilization. I will save you the trouble of thinking; it does not assist except for the stabilization factor. Edit- actions of the rectus abdominis are only trunk flexion and compression of abdomen (vacuuming)! That is straight from my kinesiology book bro!
 
ORIGIN
Pubic crest and pubic symphysis
INSERTION
5, 6, 7 costal cartilages, medial inferiorcostal margin and posterior aspect of xiphoid.

Trunk flexion.

When the insertion pulls toward the origin, the muscle is contracting, causing spinal flexion.

Which is why, when I did hanging leg raises for the first time in a few months last week, my abs were sore from my ribcage to my pelvis. I don't care what anyone *says* about it. I lift heavy things and I know what I'm doing, you can blah blah all you like, I do not give a sh*t.
 
This made my day. I find hanging leg raises to be very effective for the lower core... I suppose its just a placibo effect?.. sigh.
