I might not have felt it at the time but i was in a WORLD of pain from those V-sits the next day! I felt it ALL OVER my abs, especially my obliques.

I can't see, if i weigh 77kg and my tailbone is the only part of me touching the floor, how strong abs can possibly reduce my weight! I tried tensing my glutes which helped a tiny bit but i doubt is the "proper" way to do it. I had DP (personal trainer) check my technique and he said it looked fine, so i also have no idea about the whole lower abs theory. He said that the normal way to tighten the lower abs is laid-flat-leglifts (hard and can hurt your back) or pelvic tilts, but you can't do a pelvic tilt and keep your back straight. Let us know what your trainer says.

I put my squats and lunges up to 15kg last night at pump!!! YAY me!!!

I've had a minor hip injury (from long runs and a biomechanical foible of mine) so i've been nursing it all week with shorter runs and lots and lots of stretches. So annoying as i was getting into my groove but i guess avoiding serious injury will do more for my training than forcing the issue...
