A calisthenics course is a structured program designed to teach participants the principles and techniques of bodyweight training, helping them progress from foundational movements to more advanced skills. These courses often cater to various fitness levels, from beginners looking to build basic strength and master exercises like push-ups and squats, to intermediates aiming for pull-ups, dips, and core strength, and even advanced practitioners aspiring to master complex skills like the human flag or planche.
