hanging knee raises

[tyciol]

"lower abdominals" oy not this crap.

The rectus abdominis will stabilize the pelvis and stop it from tilting anterior, assuming you don't rest your butt on the back pad here (if you do, it removes the abs unless you actively lift your butt off the back rest).

Some of these have high pads which only rest the upper back, which could avoid cheating.

Knee raises are mostly hip flexor exercises though. The "psoas" is what I figure people mean by lower abs, since it runs underneath the rectus.

This way is easier than hanging on a chinning bar
