So Hart's workouts pulled consistent double-duty. This workout will attack your back, biceps and leg muscles in earnest, but it won't do only that. Every single move will test your abs as well.
Stand holding a dumbbell at your chest, abs tight, feet shoulder width apart. Push your butt back, keeping your chest up; squat down until your thighs are parallel to the floor. Stand back up. That’s 1 rep; do 3 sets of 10.
Elevated Plank Dumbbell Row
Get in plank position, with your right forearm on a bench and your left hand holding a dumbbell. Row the dumbbell toward your rib cage. Pause, then return to the start. That’s 1 rep; do 3 sets of 10 per side.
Stability-Ball Plank Rollout
Get in a plank on a ball. Roll forward, then back, keeping your abs tight, for 30 seconds. Rest for 15 seconds. Do 3 sets. Too easy? Hart rolls the ball in different directions, spelling out his name every set.
Stability-Ball Front Squat
Stand with your forearms pressing into a stability ball against a wall, heels off the floor. Keep pressing and squat down until your thighs are parallel to the floor. Pause, then stand. That’s 1 rep; do 3 sets of 10.
