weaks abs?

**JOHNYORK** · 02-19-2007, 07:00 PM

My upper thighs get strained when doing leg lifts and my abs don't really feel like they're being worked. Are my abs weak or am I just not focusing enough on working my abs during the movement??? Thanks.

I had, well still do have the exact same problem but i notice it more so on decline crunches. I found out the reason of that at

http://www.skippypodar.net/Fitness/abs2000.html

and heres the paragraph that explains it....

"Crunches focus your effort solely on the abdominal muscles, while Sit-Ups involve both the abdominals and the hip flexors (ilio psoas). The purpose of the rectus abdominis (the primary abdominal muscle group) is to bring your sternum closer to your pelvis. This only involves the first 30 degrees of movement from the horizontal position. Anything beyond that engages your hip flexors. The psoas (as their frequently called) attach at the front and top of the thigh, and wrap around to connect at the base of your spine. Whenever you perform a movement where you're bringing your thigh closer to your torso, you use your psoas. So, if the upper part of your thighs has ever felt sore during Sit-Ups, that's why."
