*Looking the her avatar he says*BritChick said:I used to do sit ups before I knew any better!!! I think crunches and reverse crunches are way more effective... high reps has always been what's worked best for me, but still slow and controlled... if they burn like hell they're working! (Everybody seems to have a different philosophy on ab training).
