The body is a complex machine with over 600 muscles that work together to help us perform at our best. To effectively train all these muscle groups, fitness pros recommend incorporating a training split. This involves dividing your workouts to focus on different muscle groups on different days, which allows for increased intensity and proper recovery. There are different training split options, including the full-body split, upper/lower split, push/pull/legs split, and the controversial "bro" split. Choose the split that best suits your goals and workout frequency, remembering that the overall goal is to keep your whole body active and gradually build strength and muscle.
