Mark Verstegen's Core Workout—Week Three
Workout A: W's—Standing
Bend your arms slightly and raise them at your sides as though you are making a W (your head makes the center point of the letter). Lift them at your sides, pause, and move back to the start position. Make sure you initiate movement by pulling your shoulder blades together. Do 12 reps.
