Here we Emphasizes lower abs.
Implementation: Reverse Crunches are done most
effectively lying on a Bench Press bench that has a rack at one end. (A) First
Lie down on your back on the bench and grab the rack behind you for support. Now
bend your knees and bring them up as much as you can toward your head without
lifting your pelvis off the bench. (B) This is your starting position. Now
bring your knees up as close to your face as you can, rounding your back, with
your behind coming up off the bench and crunching up to your rib cage. At the
top pause for a moment and really get a big time peak contraction. Gradually
lower your knees until your behind comes to rest on the bench again. (Don't
lower your legs any farther than this. You aren't doing Leg Raises.) Don't just
get a lot of quick reps, concentrate on doing them in a concise And controlled
movement.
