Stretch Before AND After Exercise
The purpose of stretching before exercise is to help prevent injury by lengthening the muscles and tendons, which in turn increases the range of movement. This helps ensure smoother movement and minimises injury.
Stretching after exercise is to aid in the repair and recovery of the muscles and tendons by lengthening the muscles and tendons. Stretching helps to prevent tight muscles and muscle soreness which usually follows after strenuous exercises.
Thus, stretching improves flexibility, minimises muscle pain, and helps prevent muscles injury.
