Flexibility is an often neglected component of physical fitness; yet, it is important to maintain proper posture, prevent injury, and reduce muscle soreness and tension.
Stretching is an ideal way to improve flexibility. The best time to stretch is at the end of a workout, when one’s muscles are warm and more pliable.
The American Council on Exercise recommends stretching for 30 minutes 3 times per week to improve and maintain flexibility, or stretching a minimum of 5-10 minutes at the end of every exercise session.
