Mark Verstegen's Core Workout—Week Three
Workout A: Lateral Pillar Bridge—Jumping Jack
With your body in a straight line and your elbow under your shoulder, push your hip off the ground, creating a straight line from ankle to shoulder and keeping your head in line with your spine. From this position, lift your top leg into the air as if you were doing a lateral jumping jack. Do six reps on each side.
