Training

The Triceps brachii usually lends itself well to the study of the special exercises. But in some people, it refers to the "left behind". Then you need to pay special attention to the triceps muscle, to "break" her purposefully in isolation.

Although the coaches suggest to start with the basic (mnogosloinykh exercises), in the case of the backlog of the triceps can be "start" otherwise. There are many techniques to do this: pre-fatigue the muscle isolation training and more. Only experienced guide will tell you how to act in each particular case.

The Triceps brachii are often involved in developing the chest muscles, so this should be borne in mind. But it is recommended to load no more than two times in a week to avoid overtraining muscle fibers.

The exercises Themselves are easy to find in textbooks on bodybuilding or on websites on the Internet. Many training facilities posted to the web on the video channels.

About the pain in the muscle

Unfortunately, the unpleasant feelings may experience the triceps brachii, which lead to strain, spasm. Pain can occur when you are pushing heavy objects, a sudden straightening of the arm.

Problems can cause trigger points and muscle bands. In the first case, the pain may radiate to the other areas, and the second will be very painful on palpation.

In such cases, the stretching of the heads of triceps muscle. This can massage therapist.

In conclusion

It is Not necessary to train separate heads of the triceps muscle, it's pointless. Any exercise for the triceps will work it completely.

It is Worth remembering that all people are different genetically. Differences in growth, size kotey, muscle shape, length of the tendon heads of the muscles - all this must be considered when formingyour "ideal" body. It is not necessary to look to models in bodybuilding competitions.

Information for women and girls! For the formation of the triceps don't have to go to the gym. It is enough to perform bodyweight exercises. It's push-UPS (from knees) push-UPS on bench (benches), sitting with his back to her.
