Warm up
Warm up consist of a series of exercises preparing the body to support more challenging activities with the maximum efficiency. Therefore, these exercises are preliminary to real training. The warm up should be strictly aerobic (see muscular energy), gradual and mainly dependent on natural, low intensity. It may feature anaerobic alactacid phases, but not anaerobic lactacid phases. In addition, it is necessary to perform stretching exercises, usually at the end.
