i would rather see you do leg presses than the extentions, but even better just more squats once they stop hurting... pistols and zerchers are two of my favorite variations...
have you had any deload period since the transformation contest? if your energy is high, youre probably OK, but i know youve been killing it for a while now...
your bench numbers look like theyve gone up a lot since i last looked at your workouts...
after a cut, we are primed for new growth... ive put on 20lbs since my avi, though not as clean because i live to eat
but if you keep it clean and increase your cal's id bet you could put on some nice size on this without any fat gain, thus lowering your bf% solely on the differnce in ratio on fat to muscle...
