Help your body to develop muscles so the muscles will help you to swim longer and faster.
Together with  Kamishi Swimming School we prepared a wonderful set of dryland exercises for swimmers that  they usually provide to their BREASTSTROKE swimmers. It is a selection of exercises from Swimming Anatomy book by Ian McLeod. All of them you can do at the GYM.

ARMS

Standing Double-Arm Triceps Pushdown With Rope
This exercise is good for every type of stroke, but especially for breaststroke. It mimics the final portion of the underwater pull performed off the start and each turn wall.
“In the starting position your hands are at your midline. As the elbows are extended, the hands pull the ends of the ropes outward so that when the elbows are almost locked the hands are shoulder-width apart”.

Barbell Biceps Curl

This exercise also enhances the second half of the pull phase during breaststroke.
Execution
1 . Grasp the bar using an underhand grip. Your hands should be spaced shoulder-width apart.
2 . Without leaning back, curl the bar toward your chest in an arc until the bar is level with your shoulders.
3. Return the bar to its start position at arm’s length.

SHOULDERS

Scapular Push-Up

Execution
1. Facedown, support your body weight on your toes and forearms.
2. Holding your body in a straight line, lower your chest while maintaining the shoulder position and allowing your shoulder blades to pinch together.
3. By rolling your shoulders (protraction), push your upper body upward.

External Rotation With Tubing
Execution
1. Stand sideways 4 feet ( 1 20 cm) from a pole with a piece of exercise tubing attached at elbow height. Hold the tubing in the hand farther from the pole and bend the elbow to go degrees.
2. Rotate your hand away from your torso until you have covered a gO-degree arc. Keep your forearm parallel to the floor during the entire movement.
3. Slowly return to the starting position.

CHEST

Feet-Elevated Push-Up on Physioball
“The physioball variation works the same muscle groups but is more challenging because of the unstable nature of the physioball. The exercise can be made more difficult by increasing the inflation pressure of the physioball or by resting only the toes on the physioball instead of the entire foot.”

Dip (Chest Version)
“The exercise will be particularly useful to breaststrokers because it closely mimics the final portion of the underwater pull performed off the start and each turn wall.”
Execution
1. Position yourself on a dip bar. Support your body weight with your elbows almost locked.
2. While lowering your chest downward, lean your upper body forward.
3. Stop when your upper arms are parallel to the floor or when you feel a stretch in the front part of the shoulders.
4. Push yourself upward until your elbows are almost locked.

Standing Double-Arm Medicine Ball Throw Down
“Breaststrokers will find this exercise particularly beneficial because it is similar to the underwater pull that is performed off the start and each turn wall.
Keys to getting maximum benefit from the exercise begin with initiating the throw with the arms in an elongated position. This positioning will help ensure that the exercise is initiated with a tall, upright posture. A second key is making an explosive yet controlled throw and continuing the throw until you release the ball at the hips.”
Execution
1. Using both hands, lift the medicine ball up over your head.
2. Forcefully throw the medicine ball downward, targeting a spot on the ground 1 foot (30 cm) in front of your feet.
3. Catch the medicine ball as it bounces up off the ground.

ABDOMEN

See exercises for abdomen here. They are the same for crawl and for breaststroke. Plus add the following one, one of my personal favorites:

Kneeling Chop
“Because it starts with the arms and trunk in an elongated and stretched position, this exercise helps swimmers develop confidence and strength in their stroke during the initial portion of the pulling phase of all four strokes.
Execution
1. Position yourself so that when you are kneeling, the high pulley is diagonally behind your shoulder.
2. Reaching up and back, grasp the handle with both hands.
3. Initiate the movement with your abdominal muscles. The arms should act as an extension of the torso.
4.Using an arcing movement, guide the handle downward toward the opposite knee.
5. Reverse the movement to return to the starting position.”

Physioball Prayer Roll

“To get the maximum benefit out of performing this exercise, you must stabilize the spine in a neutral position for the entire time. Additionally, the exercise targets the abdominal muscles in a way that will carry over to strengthening the undulating body movements that occur during breaststroke and butterfly.
Execution
1. Using your forearms, support your upper body on a physioball. Support your lower body with your knees and toes.
2. Set your abdominal muscles to stabilize your spine in a neutral position.
3. Roll the ball out slowly, allowing your arms to move with the ball and your knees to straighten.
4. Pause in the ending position and then return to the start.”

BACK

Standing Straight-Arm Pull-Down
“Execution
1. Stand facing the pulley machine. Using an overhand grip, position your hands slightly wider than the width of your shoulders.
2. Holding your elbows in 30 degrees of flexion, pull the bar down to your thighs in an arcing motion.
3. Bring the bar to within 1 inch (2. 5 cm) of touching your thighs and then slowly return to the starting position.”

Lumbar Extension
“Breaststroke swimmers will benefit through strengthening of the undulating or wavelike body movements that are integral to their movement through the water.

Execution
1. Lie facedown, position the bolster just below your hips, and secure your ankles.
2. From a hanging position, raise your torso until your legs and upper body are in a straight line.
3. Slowly lower your upper body back to the hanging position.”

LEGS

Standing Hip Internal Rotation
“This exercise targets a select group of muscles that are responsible for internal rotation of the hips, a movement that is primarily seen in swimming during the recovery phase of the breaststroke kick as the heels are brought toward the buttocks. Breaststrokers will therefore benefit most from the exercise. But other swimmers should not ignore the exercise, because a small rotational component takes place during the other strokes. Like the rotator cuff muscles of the shoulder, these muscles play a protective role and help stabilize the hip joint.
Execution
1. Standing on one leg, reach with your arms and trunk to the inner side of the weight-bearing foot.
2. Use the weight-bearing leg as a pivot point.
3. Reach your arms and trunk toward a point on the ceiling above and slightly behind the same shoulder.
4. Hold the free leg in a flexed position and simultaneously rotate it with the trunk, driving the knee upward toward the ceiling with the arms.”

Physioball Hamstring Curl
“Breaststrokers who want to strengthen their hamstrings will find this a useful exercise. This exercise is also valuable because it targets the hamstrings, gluteus maximus, and erector spinae, which contribute to holding a tight streamlined position.
Execution
1. Lie on your back and position a physioball under your heels.
2. Tighten your core muscles and lift your hips toward the ceiling.
3. Without letting your hips drop, pull your heels toward your buttocks.
4. Straighten your legs until your body is in a straight line extending from your ankles to your shoulders. Then repeat.”

Leg Curl
“Avoid lifting the hips off the bench when performing the exercise. Perform the movements in a slow, controlled fashion. Do not try to kick the roller pads toward your buttocks; pull them instead.
Execution
1. Lie facedown on a hamstring curl machine and hook your heels under the roller pads.
2. Pull your heels toward your buttocks in an arcing motion.
3. Slowly lower the weight to the starting position.”

Standing Hip Adduction
“Direct targeting of the adductor muscle group can help the breaststroker increase the strength and stamina of the kick.
Execution
1. Stand sideways to a backstroke flagpole with a band fixed to the pole and the ankle closer to the pole. Tighten your core muscles to stabilize your hips.
2. Allow the resistance of the band to pull your leg out to the side.
3. Keeping your knee straight, pull your leg across and in front of the stabilizing leg.
4.Slowly return to the starting position.”
