Holding Wall Squat with Ball Press
Target: Side and front abs
Start: Hold a nonweighted ball (such as an inflatable stability ball) in both hands, at chest level, and stand with back flat against a wall.
Move: Slowly squat until thighs are parallel to the floor. Touch ball against wall over right shoulder, bring it back to center, then touch it to the wall over left shoulder for one rep. Keep back flat against the wall throughout the move, abs pulled toward spine, and knees in line with ankles; do not allow knees to push beyond toes.
Repeat: Perform two sets of 10 to 12 reps with one minute of rest between sets.
