Proper calisthenics training will promote the growth of lean muscle mass, and increase your strength, mobility, flexibility, agility, and endurance. The main benefit of calisthenic training is that it can be done anywhere, and you require minimal equipment to do it. The U.S. Army recommends calisthenic training to its recruits, saying that it helps to build muscular strength and endurance, as well as improving bone and joint strength, which aids in preventing injuries. If you're a beginner, then this method of training is also perfect to help you develop a basic level of coordination, stability and muscular control, before moving on to weighted exercises.
