Lower the can behind you until the bottom of it is level with the back of your head.

3. Push-ups (Chest, shoulders, arms)
Lie on your stomach, bend your knees and cross your ankles. Bend your elbows and place your palms on the floor a bit to the side and in front of your shoulders. Straighten your arms and lift your body so you're balanced on your palms and knees. Tuck your chin a few inches toward your chest so your forehead faces the floor. Tighten your abdominals.

Bend your elbows and lower your entire body at once. Rather than trying to touch your chest to the floor, lower only until your upper arms are parallel to the floor. Push back up.

4. Lateral Raise (Shoulders)
Hold a 12- to 16-ounce soup can in each hand and stand up tall with your feet as wide as your hips. Bend your elbows a little, turn your palms towards each other and bring the cans together in front of the tops of your thighs. Pull your abdominals in and bend your knees slightly.

Lift your arms in an arc, up and out to the sides, until the cans are just below shoulder height. Slowly lower the cans back down.

5. Bench Dips (Arms)
Sit on the edge of a chair with your legs together and straight in front of you, toes pointing up. Keeping your elbows relaxed, straighten your arms, place your hands about six inches apart and firmly grip the edges of the bench. Slide your butt just off the front of the bench so that your upper body is pointing straight down. Keep your abdominals pulled in and your head centered between your shoulders.
