A word about stretching

If stretching exercises are part of your workout routine, it's best to do them after the warm-up or cool-down phase, when your muscles are already warm.

Stretching can improve flexibility and range of motion about a joint. Stretching may also help improve your performance in some activities by allowing your joints to move through their full range of motion. However, studies haven't consistently shown that stretching helps prevent muscle soreness or injury.
