Your body cannot just pick up where it left off pre-injury. An injured muscle is weaker than an out of shape muscle. You need to start back slowly – more slowly than you think! Your body will feel good long before you are ready to return to full activity. Start by doing just part of the barre the first time and work up to all of the barre exercises over a period of days or weeks. Then do barre and half of center floor. Even if you feel really good at this point in class, don’t jump yet! Your endorphins are kicking in and you will not feel pain until later. Use this slow time as an opportunity to clean up your technique. When the muscles are weak, that is the best time to correct the way you work.
