Execution
1 . Position your hands on the floor at shoulder level and slightly wider than shoulder-width apart. Support your lower body on your toes.
2.Holding your body in a straight line from your ankles to the top of your head, push your upper body upward until the elbows are almost locked.
3.Lower your body until your chest is 1 inch (2.5 cm) off the ground.
Muscles Involved
Primary:Pectoralis major, triceps brachii Secondary:Anterior deltoid
Swimming Focus
Push-ups are a useful addition to any dryland program because they can be performed in almost any setting without any equipment. They are beneficial to the swimmer as both a strengthening exercise and a stabilizing exercise. As a strengthening exercise, push-ups primarily target the triceps brachii and pectoralis major, two muscle groups used during the propulsive phase of every stroke. Push-ups also target the stabilizing muscle groups (rotator cuff and scapular stabilizers) of the shoulder joint by placing the shoulder in a closed-chain position.
You should be sure to monitor your form when performing this exercise. A common technique flaw is failure to hold the body in a straight line from the ankles to the tip of the head. Two culprits leading to this technique flaw are improper head position and weakness of the core-stabilizing musculature. Either of these problems will cause the low back to sag or arch excessively, which will place undue stress on your spine. If you are unable to maintain proper form, modify the exercise by starting from the knees instead of the toes.
ASAFETY TIP
Lowering the chest too far can cause extra stress on the ante
Lowering the chest too far can cause extra stress on the anterior part ofthe shoulder. Those with a shoulder injury or a history ofone should avoid this movement.
VARIATIONS
Plyometric Push-Up
Plyometric push-ups emphasize an explosive muscle contraction, in contrast with regular push-ups, which emphasize slow, controlled movements. The rapid, explosive movement can be useful in teaching swimmers how to explode off the turn wall when performing open turns. Plyometric push-ups are performed by explosively pushing your upper body upward so that your hands leave the ground. Caution is required when using this exercise with younger swimmers, who may not have the coordination to catch themselves at the end of the exercise.
Kneeling Push-Up
The kneeling push-up is a good transitional variation for swimmers who are just learning how to perform push-ups or for those who do not have the necessary upper-body or core strength to maintain the correct positioning.
Tri ceps
Execution
1 . Position your hands on the floor at shoulder level and slightly wider than shoulder-width apart.
2.With your feet resting on an elevated surface such as a swimming block and your body in a straight line from your ankles to the top of your head, push your upper body upward until the elbows are almost locked.
3.Lower your body until your chest is 1 inch (2.5 cm) off the ground.
Muscles Involved
Primary:Pectoralis major (clavicular head) Secondary:Anterior deltoid, triceps brachii
ASAFETYTIP
Because ofthe need for increased strength and complexity, young swimmers should not perform this exercise.
Swimming Focus
The altered body position emphasizes the clavicular (upper) portion of the pectoralis major and the anterior deltoid muscle. The higher the feet are elevated, the more the emphasis shifts. This altered emphasis targets the portion of the pectoralis major that is engaged during the front half of the pulling phase for butterfly, freestyle, and breaststroke. Be aware that the altered positioning creates a much more challenging exercise and places extra stress on the shoulder joint, so only those who can maintain proper form and technique with a normal push-up should perform this exercise. A good way to transition into incorporating this exercise is to increase the elevation of the feet incrementally.
