This program hits all major muscle groups in the least amount of time. Always warm up for at least five minutes (break a light sweat) before any workout.

Do 15 repetitions of each exercise:

• Squats: Stand with feet slightly wider than shoulder-width apart, toes slightly pointed outward, head up and back arched, arms extended straight out in front at shoulder height. Bend knees, but keep your knees behind your toes (imagine sitting down in a chair). Butt goes out and chest stays up. Descend slowly, never going farther than thighs parallel to floor. Slowly come back up and repeat, never allowing legs to straighten completely between repetitions.
• Dumbbell Row: Assume a position similar to that of starting a lawn mower: one foot forward and the other back, knees bent, back is arched. Using a light dumbbell (in the same hand as the leg that is in the back), pull from an arm-outstretched position toward your hip. Keep elbow close to the body.
• Lunge: Start with feet together and arms out to side for balance. Step forward so that front knee is on a 90-degree angle. Maintain this position. Push off back leg so that forward leg straightens, but do not step all the way back into starting position. Repeat with other leg.
• Pushups: Can be performed either on the floor or against a wall. Hands will be just barely wider than shoulder-width apart. Slowly bring chest to floor or wall while keeping the abdomen tight. Body should remain in a straight line. Slowly push off floor or against wall and bring body back to starting position.

Repeat program. Cool down for five minutes and then stretch.

Always check with your doctor before starting any exercise program.
