CORE TRAINING refers to exercises that focus on the functional muscles! This is ideal for achieving good posture, a harmonious body and balanced strength.
In fact, during a strength training session, people generally only use one muscle during the execution of a movement. Core training will automatically solicit a set of muscle chains, with a dominant focus on the central part of your body, the abdominals and the lumbar region. This will allow you, sedentary or sporty, to develop useful strength.
