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.

Pull to the belly, squeeze the shoulder blades, keep the torso still.
Choose a flat bench and place a dumbbell on each side of it. Place the right leg on top of the end of the bench, bend your torso forward from the waist until your upper body is parallel to the floor, and place your right hand on the other end of the bench for support. Use the left hand to pick up the dumbbell on the floor and hold the weight while keeping your lower back straight. The palm of the hand should be facing your torso. This will be your starting position. Pull the resistance straight up to the side of your chest, keeping your upper arm close to your side and keeping the torso stationary. Breathe out as you perform this step. Tip: Concentrate on squeezing the back muscles once you reach the full contracted position. Also, make sure that the force is performed with the back muscles and not the arms. Finally, the upper torso should remain stationary and only the arms should move. The forearms should do no other work except for holding the dumbbell; therefore do not try to pull the dumbbell up using the forearms. Lower the resistance straight down to the starting position. Breathe in as you perform this step. Repeat the movement for the specified amount of repetitions. Switch sides and repeat again with the other arm.

Control the weight in both directions and stop short of failure.
Pick a couple of dumbbells and stand with a straight torso and the dumbbells on front of your thighs at arms length with the palms of the hand facing your thighs. This will be your starting position. While maintaining the torso stationary (no swinging), lift the left dumbbell to the front with a slight bend on the elbow and the palms of the hands always facing down. Continue to go up until you arm is slightly above parallel to the floor. Exhale as you execute this portion of the movement and pause for a second at the top. Inhale after the second pause. Now lower the dumbbell back down slowly to the starting position as you simultaneously lift the right dumbbell. Continue alternating in this fashion until all of the recommended amount of repetitions have been performed for each arm.

Elbows pinned at your sides. Lower it slower than you lift it.
Stand (torso upright) with a dumbbell in each hand held at arms length. The elbows should be close to the torso and the palms of your hand should be facing your thighs. While holding the upper arm stationary, curl the right weight as you rotate the palm of the hands until they are facing forward. At this point continue contracting the biceps as you breathe out until your biceps is fully contracted and the dumbbells are at shoulder level. Hold the contracted position for a second as you squeeze the biceps. Tip: Only the forearms should move. Slowly begin to bring the dumbbell back to the starting position as your breathe in. Tip: Remember to twist the palms back to the starting position (facing your thighs) as you come down. Repeat the movement with the left hand. This equals one repetition. Continue alternating in this manner for the recommended amount of repetitions.

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 with your torso upright holding two dumbbells in your hands by your sides. This will be your starting position. Step forward with your right leg around 2 feet or so from the foot being left stationary behind and lower your upper body down, while keeping the torso upright and maintaining balance. Inhale as you go down. Note: As in the other exercises, do not allow your knee to go forward beyond your toes as you come down, as this will put undue stress on the knee joint. Make sure that you keep your front shin perpendicular to the ground. Using mainly the heel of your foot, push up and go back to the starting position as you exhale. Repeat the movement for the recommended amount of repetitions and then perform with the left leg.

Hips back, back flat, bar close to the legs. Stand up by squeezing the glutes.
Grasp a couple of dumbbells holding them by your side at arm's length. Stand with your torso straight and your legs spaced using a shoulder width or narrower stance. The knees should be slightly bent. This is your starting position. Keeping the knees stationary, lower the dumbbells to over the top of your feet by bending at the waist while keeping your back straight. Keep moving forward as if you were going to pick something from the floor until you feel a stretch on the hamstrings. Exhale as you perform this movement. Start bringing your torso up straight again by extending your hips and waist until you are back at the starting position. Inhale as you perform this movement. Repeat for the recommended amount of repetitions.

Curl the ribs toward the hips. Don't pull on your neck.
Lie down on the floor with your legs fully extended and arms to the side of your torso with the palms on the floor. Your arms should be stationary for the entire exercise. Move your legs up so that your thighs are perpendicular to the floor and feet are together and parallel to the floor. This is the starting position. While inhaling, move your legs towards the torso as you roll your pelvis backwards and you raise your hips off the floor. At the end of this movement your knees will be touching your chest. Hold the contraction for a second and move your legs back to the starting position while exhaling. Repeat for the recommended amount of repetitions.

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.

Pull to the belly, squeeze the shoulder blades, keep the torso still.
With a dumbbell in each hand (palms facing your torso), bend your knees slightly and bring your torso forward by bending at the waist; as you bend make sure to keep your back straight until it is almost parallel to the floor. Tip: Make sure that you keep the head up. The weights should hang directly in front of you as your arms hang perpendicular to the floor and your torso. This is your starting position. While keeping the torso stationary, lift the dumbbells to your side (as you breathe out), keeping the elbows close to the body (do not exert any force with the forearm other than holding the weights). On the top contracted position, squeeze the back muscles and hold for a second. Slowly lower the weight again to the starting position as you inhale. Repeat for the recommended amount of repetitions.

Lighter than you think. Lead with the elbows to shoulder height, no swing.
Pick a couple of dumbbells and stand with a straight torso and the dumbbells by your side at arms length with the palms of the hand facing you. This will be your starting position. While maintaining the torso in a stationary position (no swinging), lift the dumbbells to your side with a slight bend on the elbow and the hands slightly tilted forward as if pouring water in a glass. Continue to go up until you arms are parallel to the floor. Exhale as you execute this movement and pause for a second at the top. Lower the dumbbells back down slowly to the starting position as you inhale. Repeat for the recommended amount of repetitions.

Only the forearms move — lock the elbows in place and squeeze at the bottom.
Start with a dumbbell in each hand and your palms facing your torso. Keep your back straight with a slight bend in the knees and bend forward at the waist. Your torso should be almost parallel to the floor. Make sure to keep your head up. Your upper arms should be close to your torso and parallel to the floor. Your forearms should be pointed towards the floor as you hold the weights. There should be a 90-degree angle formed between your forearm and upper arm. This is your starting position. Now, while keeping your upper arms stationary, exhale and use your triceps to lift the weights until the arm is fully extended. Focus on moving the forearm. After a brief pause at the top contraction, inhale and slowly lower the dumbbells back down to the starting position. Repeat the movement for the prescribed amount of repetitions.

Hips back, back flat, bar close to the legs. Stand up by squeezing the glutes.
Stand with feet hip-width apart holding a dumbbell in each hand in front of your thighs. Push your hips back and hinge forward, lowering the dumbbells along your legs. Keep your back flat and lower the dumbbells until you feel a stretch in your hamstrings. Drive your hips forward to return to the standing position. Repeat for the desired number of repetitions.

Brace hard, break at the hips and knees together, knees tracking over the toes.
Stand up straight while holding a dumbbell on each hand (palms facing the side of your legs). Position your legs using a shoulder width medium stance with the toes slightly pointed out. Keep your head up at all times as looking down will get you off balance and also maintain a straight back. This will be your starting position. Note: For the purposes of this discussion we will use the medium stance described above which targets overall development; however you can choose any of the three stances discussed in the foot stances section. Begin to slowly lower your torso by bending the knees as you maintain a straight posture with the head up. Continue down until your thighs are parallel to the floor. Tip: If you performed the exercise correctly, the front of the knees should make an imaginary straight line with the toes that is perpendicular to the front. If your knees are past that imaginary line (if they are past your toes) then you are placing undue stress on the knee and the exercise has been performed incorrectly. Begin to raise your torso as you exhale by pushing the floor with the heel of your foot mainly as you straighten the legs again and go back to the starting position. Repeat for the recommended amount of repetitions.

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.

Only the forearms move — lock the elbows in place and squeeze at the bottom.
Kneel on the floor or an exercise mat and bend at the waist with your arms extended in front of you (perpendicular to the torso) in order to get into a kneeling push-up position but with the arms spaced at shoulder width. Your head should be looking forward and the bend of the knees should create a 90-degree angle between the hamstrings and the calves. This will be your starting position. As you exhale, lift up your right leg until the hamstrings are in line with the back while maintaining the 90-degree angle bend. Contract the glutes throughout this movement and hold the contraction at the top for a second. Tip: At the end of the movement the upper leg should be parallel to the floor while the calf should be perpendicular to it. Go back to the initial position as you inhale and now repeat with the left leg. Continue to alternate legs until all of the recommended repetitions have been performed.
