WALL TO WALL
You won’t be able to find an excuse around this one: To build strength and muscle in your lower body, from your upper back to your calves, all you really need to do is use empty wall space. Add a pair of 5- to 10-pound dumbbells for a super-duty workout of glutes, hips, legs, and arms.

Grab your weights and stand with your back flat against a wall, keeping shoulders and spine firmly against it. Then, walk your feet about two feet away from the edge of the wall.

Slowly slide your torso down the wall until you are sitting with thighs parallel to floor and knees bent at 90-degree angles. Keep ankles directly under knees and hold this position.

Alternate super-slow punches at chest level for two sets of 20 counts.
