The training system known as contrast sets is specifically designed to enhance both strength and power simultaneously. This method typically involves performing a high-intensity exercise, such as a heavy lift, immediately followed by a lighter, explosive movement that targets the same muscle group. For instance, a common example would be performing a set of squats using a heavy load followed immediately by jump squats.

This approach leverages the principle of post-activation potentiation, which optimally prepares the muscles for explosive power outputs after being exposed to a heavy load. By alternating between these different types of exercises, contrast sets promote neuromuscular adaptations, improving both maximal strength and the ability to generate power rapidly.

Other methods, while effective for various training goals, do not simultaneously optimize strength and power to the same degree. For instance, circuit training is primarily focused on endurance and may not provide the heavy loads necessary for significant strength gains. Pyramid sets and supersets also have specific applications that may target either strength or hypertrophy but do not directly combine the focus on both strength and explosive power as effectively as contrast sets do.
