What role does a secondary mover play in a resistance training exercise?

In resistance training exercises, the secondary mover, often referred to as the synergist, plays an important role by assisting the primary mover, or prime mover, in completing the movement. While the prime mover is responsible for generating the majority of force needed for the exercise, secondary movers help by contributing additional force or stabilizing the joint involved in the movement. This collaboration allows for more efficient and effective execution of the exercise.

For example, in a bench press, the chest muscles serve as the prime movers, while the shoulders and triceps act as secondary movers, providing support and balance during the lift. The assistance from these secondary movers enhances overall performance and reduces the risk of injury by ensuring that the body is properly supported and maintained in the correct alignment throughout the exercise.
