The major joints of the body ( the coxofemural joints and the joints of the elbow and the knee ) shouldn't be neglected, since they're the most exposed to effort. Regarding the correctness of the exercises, it is usually recommended that the standard amplitude of a joint not be forced. If the goal of the coaching is to extend the mobility of the joints, the body must be thoroughly heated up before the suppleness exercises.
All of the body must be warmed up with aerobic exercises for approximately 5-10 mins. This is required for steadily inflating the temperature of the entire body, so unquestioningly of the joints which are going to be concerned in the effort. For a similar purpose, the stretching exercises are crucial and effective. From the large area of force exercises, one must avoid the positions which involve a second of pressure of the backbone and the partial repetitions which don't open or close a joint fully. In the case of efforts in which the body is susceptible to repeated shocks, like running, jumping, special attention must be paid to strategies intended to moisten, to melt the impact. In sports which encourage deformation, partial development of the body, like cycling, tennis, soccer, it's required to try to hold a balance between the muscles which are less concerned in effort during explicit coaching and the ones overexerted. Compensating exercises can always be found for each agonist or opponent muscle. It's also crucial to alter the exercises frequently to avoid routine, which is terribly exasperating for the athlete who trains continually, for a while, in the same program. If you consider these sides of individual or collective coaching, the efficacy of your coaching will improve.
