1. Supine Pull-Ups (works major muscles in back, shoulders, and biceps) Use two chairs and a pole - a heavy broom handle works well. WARNING: make sure the chairs are stable and that the broom handle is strong enough to take your weight. You could be SEVERELY injured if the pole were to break or the chairs to slip. Lie on your back underneath a low bar. Grab the bar with a wide overhand grip. Pull up. Lower and repeat for 6-8 reps.
3. Push-Ups (chest, triceps, shoulders) The key when targeting the chest with Push-Ups is the direction in which your elbows travel. As with bench presses, the elbows must move AWAY FROM THE BODY to target your chest, and be kept CLOSE TO THE BODY to target the triceps. Place each hand just outside your shoulders, slightly behind the line of your shoulders. Hands pointing straight ahead, upper body rigid as a board. 6-15 reps.
5. Push-Ups, Triceps Position (you guessed it - triceps, and some chest) Begin with fingers facing forward in position from #3, hands slightly LESS than shoulder width apart. Lower your body to the floor keeping arms in against your body. Push up. 6-8 reps.
7. One-Legged Squats (front thighs, glutes, hamstrings) Stand perpendicular to a wall, about arm's length away from it. Extend your arm out to the side and place your palm against the wall at just under shoulder-height. Angle the foot farthest from the wall at 45 degrees. Bend the other leg back. Keeping your body upright, lower yourself until the non-weight-bearing knee is close to (but not touching) the ground. Support yourself by leaning against the wall. Press yourself back up to starting position. Repeat 6-8 reps.
9. Lunges Begin the lunge by taking a large step forward, keeping your head up and torso erect. Lower your hips and allow your trailing knee to drop to a point just before it touches the floor - never let the knee touch the floor. To return to the start, push off with your forward leg and then step back when the knee is completely straight. Repeat with other leg, 10-15 reps each leg.
