Ball as Bench
Because you are working on a mobile surface and moving the arms through a full range of motion, you will not be able to load up with heavy weights. Begin with 1- or 2-pound weights. Later you can increase the weight slightly if desired. Lying back on the ball will set you up for a fuller range of movement, more than you could get on a mat and more comfortably than on a bench. Your head, neck, and shoulders are totally supported on the ball but the low back is off the ball to work the buttocks. Keep the hips lifted and the abdominals working to protect the low back. The center of the kneecap should be tracking over the second toe, feet parallel and hip-distance apart.

Purpose Chest Press works the pectorals and triceps; the single-arm work requires the obliques and deep rotators of the spine to stabilize the rib cage. Flies work the deltoids and pectorals. Tricep Isolator works the triceps muscles of your upper arms. Pullovers work the pectorals, intercostals, serratus, and abdominals.

Watchpoints • Make sure your head and neck are totally supported by the ball and not hanging backward. • For Chest Press and Flies, keep your weights at heart level; don’t let them drift up to head level. • When extending the arms, don’t lock the elbow: keep the elbow slightly bent in the top position. • Keep the abdominals tight and the buttock muscles activated to keep the hips working against gravity. • Keep the shoulder blades in place. • If your low back begins to hurt, use the modification below.

starting position
Sit on your ball. Walk your feet out and let the ball roll under you until your head and neck are totally supported by the ball. Hips are up; abdominals are engaged.

movement 1: chest press
1. Begin with the weights resting on the side of your chest, just above the armpits. The palms face forward. Inhale to prepare. 2. Exhale to raise the arms up to shoulder level, keeping the shoulder blades on the ball. 3. Repeat eight to ten times. Then try the same exercise with palms facing inward.

movement 2: single-arm chest press
1. Place the weight in your left hand. Begin with the left hand resting on the side of your chest just above the armpit. The palms face forward. Place your right hand on your hip or raise it directly above your shoulder as a counterbalance. 2. On the exhalation raise your left arm, keeping your body steady on the ball. 3. Repeat eight to ten times. Then perform the same exercise on the other side.

movement 3: flies
1. Open your arms to the sides, keeping the elbows slightly bent. Hug the ball with the back of your upper arms. 2. Keeping your elbows slightly bent, exhale to squeeze your arms together in a large semicircle, as if hugging a thick tree. 3. Reverse the circular motion to return to bottom. Repeat eight to ten times.

On the Belly
Because these exercises are performed in extension on a mobile surface, the muscles across the back--the erectors and the postural muscles--work as much as the arm and shoulder muscles. Keep your back straight and your abdominals pulled in as you squeeze through the upper back, pulling the elbows up and back. Keep the chin tucked and maintain a gaze focused toward the mat to stabilize the head and neck. For an added challenge, place one hand on a soggy small ball directly below the shoulder, but take care that the shoulder of the hand on the small ball remains down and not up by your ear. Any of these exercises can also be performed on your knees.

Purpose Movement 1, single-arm row, works the latissimus and the muscles of the shoulder. Movement 2 targets the triceps and the back extensors. Breaststroke works the trapezius and back extensors. Reverse flies work the posterior deltoid.

Watchpoints • Engage the abdominals to protect the low back. • If your low back is straining, do the modification on the knees or avoid the exercise. • Keep the movement slow and controlled. • Keep extended through the spine; the neck is long but not hyperextended. • Keep your gaze on the mat.

starting position
Digging your toes into your sticky mat, place one hand on a soggy small ball or on the mat. Hold one or two small weights in one hand. Pull in the navel. Keep the spine long, the head aligned at the top of the spine. Your gaze is on the mat.

movement 1: single arm row
1. Inhale and exhale to pull your elbow upward, lifting the weights toward your ribcage. Keep your arms close to your body. 2. Return to the start position. Keep your back straight at all times, abdominals engaged. 3. Repeat eight to ten times on one side, then switch to the other side.

movement 2: triceps targetter
1. Place one hand on a soggy small ball or on the mat. Place 1- or 2-pound weights in one hand and bend the elbow back to the waist. Inhale. 2. Exhale to extend the arm. Inhale to bend the arm. Keep the upper arm stabilized in space as your elbow bends and stretches. Your gaze is on the mat. 3. Repeat eight to ten times, then switch arms and work the other side.

movement 3: breaststroke
1. Start with no weight or 1-pound weights just in front of the shoulder. Inhale. 2. Exhale to extend the arms straight forward, keeping shoulders down and away from the ears. The gaze is on the mat. 3. Inhale to sweep your arms all the way around and back to your thighs, lifting your upper body slightly. Your gaze remains on the mat. 4. Repeat five times, slow and smooth.
