30-Minute Abs: Week 1, Workout I
Hanging Side-to-Side Leg Raise
Sets: 3-4 Reps: 6-8 Rest: 90 Seconds
Grab a chinup bar with an overhand, shoulder-width grip and hang from it . Contract our abs and raise your legs up to your left side until they are in line with your left hand . Reverse the motion until your legs are hanging again, then raise them up to the right side . Lower your legs back to the starting position. That's one rep. If this is too difficult, perform the move with your knees bent 90 degrees.
