When should you stretch?
The answer to this question is you need to stretch when warm and stretch before you end your workout. You do not need to stretch when your body is cold and tight. You need to at least get your body slightly warmed up before you stretch. You can do this with a brisk walk or some calisthenics, or have a set time after you slowly start to stop and stretch. If you stretch your body when it is cold, you risk injuring yourself and your muscles not reacting properly. At the end of your workout, you need to spend a few minutes doing some stretches while your body is cooling off. Your body will have the tendency to seize up at the end of a hard workout. Make sure to budget some time in your workout to stretch at the end.
