The definition of flexibility is the range of movement we have at any chosen joint. This section is definitely neglected by most people; the importance of a good range of movement is often overlooked. After any form of exercise it is important to stretch. As we exercise our muscles are contracting and becoming shorter. Even every day life we put our body through many tasks that will place pressure on our joints and muscles, stretching them out will ensure we don’t develop bad posture. This area of exercise will also help with muscle strains and back problems.
