Complex training is a type of strength and conditioning program that involves performing multiple exercises in one workout session. The goal of complex training is to improve overall fitness by working several muscle groups simultaneously, allowing for more efficient use of time and energy. This type of training can involve a variety of movements and equipment, such as compound lifts, plyometrics, and cardiovascular exercises. Complex training is often used in sports conditioning programs to improve athletic performance by simulating real-life situations where multiple muscle groups are engaged simultaneously.
