Elbows tucked to about 45 degrees, touch the chest, then drive the floor away.
Lie on the floor face down and place your hands about 36 inches apart while holding your torso up at arms length. Next, lower yourself downward until your chest almost touches the floor as you inhale. Now breathe out and press your upper body back up to the starting position while squeezing your chest. After a brief pause at the top contracted position, you can begin to lower yourself downward again for as many repetitions as needed.

Touch the upper chest and keep your shoulder blades pinned back into the bench.
Stand facing bench or sturdy elevated platform. Place hands on edge of bench or platform, slightly wider than shoulder width. Position forefoot back from bench or platform with arms and body straight. Arms should be perpendicular to body. Keeping body straight, lower chest to edge of box or platform by bending arms. Push body up until arms are extended. Repeat.

Control the weight in both directions and stop short of failure.
To begin, lie straight and face down on the floor or exercise mat. Your arms should be fully extended in front of you. This is the starting position. Simultaneously raise your arms, legs, and chest off of the floor and hold this contraction for 2 seconds. Tip: Squeeze your lower back to get the best results from this exercise. Remember to exhale during this movement. Note: When holding the contracted position, you should look like superman when he is flying. Slowly begin to lower your arms, legs and chest back down to the starting position while inhaling. Repeat for the recommended amount of repetitions prescribed in your program.
StartBrace like you're about to be punched. Nothing else moves.
Get into pushup position on the toes with your hands just outside of shoulder width. Perform a pushup by allowing the elbows to flex. As you descend, keep your body straight. Do one pushup and as you come up, shift your weight on the left side of the body, twist to the side while bringing the right arm up towards the ceiling in a side plank. Lower the arm back to the floor for another pushup and then twist to the other side. Repeat the series, alternating each side, for 10 or more reps.

Brace hard, break at the hips and knees together, knees tracking over the toes.
Stand with your feet shoulder width apart. You can place your hands behind your head. This will be your starting position. Begin the movement by flexing your knees and hips, sitting back with your hips. Continue down to full depth if you are able,and quickly reverse the motion until you return to the starting position. As you squat, keep your head and chest up and push your knees out.

Front shin vertical, torso tall, drive through the front heel.
Stand facing a box or bench of an appropriate height with your feet together. This will be your starting position. Begin the movement by stepping up, putting your left foot on the top of the bench. Extend through the hip and knee of your front leg to stand up on the box. As you stand on the box with your left leg, flex your right knee and hip, bringing your knee as high as you can. Reverse this motion to step down off the box, and then repeat the sequence on the opposite leg.

Control the weight in both directions and stop short of failure.
Begin in a comfortable standing position with your knees slightly bent. Hold your hands in front of you, palms down with your fingertips together at chest height. This will be your starting position. Rapidly dip down into a quarter squat and immediately explode upward. Drive the knees towards the chest, attempting to touch them to the palms of the hands. Jump as high as you can, raising your knees up, and then ensure a good land be re-extending your legs, absorbing impact through be allowing the knees to rebend.

Curl the ribs toward the hips. Don't pull on your neck.
Lie flat on your back with your feet flat on the ground, or resting on a bench with your knees bent at a 90 degree angle. If you are resting your feet on a bench, place them three to four inches apart and point your toes inward so they touch. Now place your hands lightly on either side of your head keeping your elbows in. Tip: Don't lock your fingers behind your head. While pushing the small of your back down in the floor to better isolate your abdominal muscles, begin to roll your shoulders off the floor. Continue to push down as hard as you can with your lower back as you contract your abdominals and exhale. Your shoulders should come up off the floor only about four inches, and your lower back should remain on the floor. At the top of the movement, contract your abdominals hard and keep the contraction for a second. Tip: Focus on slow, controlled movement - don't cheat yourself by using momentum. After the one second contraction, begin to come down slowly again to the starting position as you inhale. Repeat for the recommended amount of repetitions.

Elbows tucked to about 45 degrees, touch the chest, then drive the floor away.
With your hands wide apart, support your body on your toes and hands in a plank position. Your elbows should be extended and your body straight. Do not allow your hips to sag. This will be your starting position. To begin, allow the elbows to flex, lowering your chest to the floor as you inhale. Using your pectoral muscles, press your upper body back up to the starting position by extending the elbows. Exhale as you perform this step. After pausing at the contracted position, repeat the movement for the prescribed amount of repetitions.

Touch the upper chest and keep your shoulder blades pinned back into the bench.
Stand facing a Smith machine bar or sturdy elevated platform at an appropriate height. Place your hands on the bar, with your hands about shoulder width apart. Position your feet back from the bar with arms and body straight. This will be your starting position. Keeping your body straight, lower your chest to the bar by bending the arms. Return to the starting position by extending the elbows, pressing yourself back up.

Only the forearms move — lock the elbows in place and squeeze at the bottom.
Position a bar in a rack at chest height. Standing, take a shoulder width grip on the bar and step a yard or two back, feet together and arms extended so that you are leaning on the bar. This will be your starting position. Begin by flexing the elbow, lowering yourself towards the bar. Pause, and then reverse the motion by extending the elbows. Progress from bodyweight by adding chains over your shoulders.

Brace like you're about to be punched. Nothing else moves.
Get into a prone position on the floor, supporting your weight on your toes and your forearms. Your arms are bent and directly below the shoulder. Keep your body straight at all times, and hold this position as long as possible. To increase difficulty, an arm or leg can be raised.

Brace hard, break at the hips and knees together, knees tracking over the toes.
Stand with your feet shoulder width apart. You can place your hands behind your head. This will be your starting position. Begin the movement by flexing your knees and hips, sitting back with your hips. Continue down to full depth if you are able,and quickly reverse the motion until you return to the starting position. As you squat, keep your head and chest up and push your knees out.

Control the weight in both directions and stop short of failure.
On a flat bench lie facedown with the hips on the edge of the bench, the legs straight with toes high off the floor and with the arms on top of the bench holding on to the front edge. Squeeze your glutes and hamstrings and straighten the legs until they are level with the hips. This will be your starting position. Start the movement by lifting the left leg higher than the right leg. Then lower the left leg as you lift the right leg. Continue alternating in this manner (as though you are doing a flutter kick in water) until you have done the recommended amount of repetitions for each leg. Make sure that you keep a controlled movement at all times. Tip: You will breathe normally as you perform this movement.

Ribs down, chin tucked, and hold the squeeze at the top for a full second.
Lie flat on the floor on your back with the hands by your side and your knees bent. Your feet should be placed around shoulder width. This will be your starting position. Pushing mainly with your heels, lift your hips off the floor while keeping your back straight. Breathe out as you perform this part of the motion and hold at the top for a second. Slowly go back to the starting position as you breathe in.

Curl the ribs toward the hips. Don't pull on your neck.
Lay flat on the floor with your arms next to your sides. Now bend your knees at around a 75 degree angle and lift your feet off the floor by around 2 inches. Using your lower abs, bring your knees in towards you as you maintain the 75 degree angle bend in your legs. Continue this movement until you raise your hips off of the floor by rolling your pelvis backward. Breathe out as you perform this portion of the movement. Tip: At the end of the movement your knees will be over your chest. Squeeze your abs at the top of the movement for a second and then return to the starting position slowly as you breathe in. Tip: Maintain a controlled motion at all times. Repeat for the recommended amount of repetitions.
