Final answer:
The leg press is an example of a substitute exercise for the movement sequence of squatting. It provides similar benefits to the squat but with different mechanics or equipment. The leg press targets similar muscle groups as the squat such as the quadriceps, hamstrings, and glutes.
Step-by-step explanation:
The leg press is an example of a substitute for the movement sequence of squatting. A substitute exercise can be used as an alternative to the original exercise, providing similar benefits but with different mechanics or equipment. In the case of the leg press, it targets similar muscle groups as the squat, such as the quadriceps, hamstrings, and glutes, but it uses a different movement pattern and equipment. The leg press is often used as a substitute for squats when individuals have certain limitations or injuries that prevent them from performing the squat exercise.
On the other hand, progression refers to making an exercise more challenging over time to continue making progress and achieving fitness goals. Regression, on the other hand, involves making an exercise easier or less intense to accommodate different fitness levels or to allow for recovery after an injury or illness. Isolation exercises are those that target specific muscle groups or joints without involving other muscles or joint actions. The leg press can be considered as a substitute exercise for the squat, but it is not an isolation exercise.
