1, triple differentiation: divide the body into three main parts for exercise, namely chest, back and legs. Trainers will train these three parts in each training cycle. This method usually has two cycles per week, such as chest training on Monday, back training on Tuesday, leg training on Wednesday, and then the next cycle.

2. Five points: divide the body into five different muscle groups, including chest, back, shoulders, legs and arms (usually biceps brachii and triceps brachii of the upper arm). Trainers will focus on training these five muscle groups on different training days. This method aims to give each muscle group enough time to recover and grow, because each muscle group has a week's rest.
