Slow, controlled movements are the key to maximizing the benefits of this exercise. The best way to enforce this is to pause for one to two seconds when the arm is fully extended, with a focus on squeezing the triceps tight, and to pause for one to two seconds when the arm is in the 90-degree bent-elbow position. This approach will prevent you from generating a pendulum-like swinging motion with the dumbbell, which is a form of cheating.



SAFETY TIP

As in swimming, your head must stay in alignment with your spine. Lifting your head up will lead to arching of the back, and looking down at your feet will roll your shoulders forward. Either action will take the spine out of its safe zone and increase the potential for an exercise-related injury.


VARIATION Dumbbell Kickback With Tubing

This variation is useful when performing dryland exercises on a pool deck where no exercise bench is available to brace yourself. The amount of tension initially placed on the exercise cord should be light enough to allow you to reach the fully extended ending position. This exercise can be modified so that both arms do the kickbacks at the same time. Be sure to move in a slow, controlled manner and to avoid bouncing the upper body.




Close-Grip Push-Up




Execution


1. Facedown, slide both hands under your chest so that your thumbs touch along the midline of your body at nipple level. Your toes support your lower body.

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:Triceps brachii, pectoralis major

Secondary:Pectoralis minor, anterior deltoid, anconeus, wrist and finger flexors


SAFETY TIP

If you are currently having shoulder pain or have a history of shoulder problems, avoid dropping too far into the ending position because doing so places extra stress on the shoulder joint. A good guideline to follow is to stop when the shoulders reach neutral. Because of the potential for increased stress on the shoulders, young swimmers who are still working to develop their overall shoulder strength should avoid this exercise.


Swimming Focus

Push-ups are one of the best dryland exercises because they can be performed anywhere and do not require any equipment. Another benefit is that they place the shoulder in what is called a closed-chain position; exercises that do this significantly enhance the recruitment of stabilizing muscles surrounding the shoulder joint.

While performing this or any other type of push-up, one of the main focuses should be on maintaining the body in a straight line from the ankles to the top of the head, just as if you were in a streamlined position in the water. A common mistake is to take the head out of line with the rest of the spine, which will lead to either arching of the back or dropping the hips to the ground. Maintaining proper form, especially a straight spine, is important; therefore, those who cannot maintain this position should modify the exercise by starting on their knees instead of their toes.



VARIATION

Close-Grip Push-Up With Medicine Ball

To increase the complexity and difficulty of this exercise, try using a medicine ball as the base of support. Choose a medicine ball that is approximately half the width of your chest. Position the ball so that its center is aligned with the middle of your chest and in line with your nipples.



Close-Grip Bench Press




Execution


1. Lie face up on a bench and grasp the bar using an overhand grip with your hands spaced 8 to 12 inches (20 to 30 cm) apart.

2. Lower the bar to a point just below the nipple line and allow your elbows to drift out at a 45-degree angle.

3. As soon as the bar touches your chest, reverse the movement.


Muscles Involved

Primary:Triceps brachii, pectoralis major

Secondary:Pectoralis minor, anterior deltoid, anconeus, wrist and finger flexors

Обручев Сергей Владимирович (1891-1965 гг.) известный советский геолог и географ, член-корр. АН СССР. Высоко образованный человек - владел 10 иностранными языками. Сын академика В.А.Обручева, . будущий исследователь Азии, Сибири, Якутии, Арктики, родился в г. Иркутске, получил геологическое образование в Московском университете, закончив который в 1915 г., после недолгой работы на кафедре оказался в Геологическом комитете и был командирован для изучения геологии в Сибирь, на р. Ангара в ее среднем течении. Здесь он провел несколько полевых сезонов. Наиболее известны его экспедиции на Северо-Восток СССР. Совершил одно из значительных географических открытий в северо-восточной Азии - системы хр. Черского - водораздельной части Яно-Индигирского междуречья. На северо-востоке Якутии в Оймяконе им был установлен Полюс холода северного полушария На Среднесибирском плоскогорье - открыт один из крупнейших в мире - Тунгусский угольный бассейн. С.В. Обручев был организатором и руководителем более 40 экспедиций в неосвоенных и трудно доступных территориях России. С 1939 на протяжении более 15 лет его полевые работы были связаны с Прибайкальем и Саяно-Тувинским нагорьем. В честь С.В.Обручева названы горы на Северо-востоке страны, полуостров и мыс на Новой Земле.
