Partner MB Sit-ups

Beginners and persons who suffer with lower back pain should avoid this exercise.

Both partners need to lie on their backs, with partner 1 holding a suitable sized medicine ball, either on your chest, (easier) or with arms extended behind your head, (harder), your legs should be hooked around each others ankles, at the start of each rep.

Both partners will inhale and lift themselves up to a high angle of 75 - 90 degrees, with partner 1 passing the ball to partner 2. Once the pass has been completed, both partners then return back to the starting position, prior to repeating the complete movement again, however partner 2, now passes the ball to partner 1.

Working this exercise at speed reduces the benefits for the abs and increases the risk of lower back injury.
