It is not clear whether the stretches that are usually recommended before vigorous activity are beneficial. However, as a precaution, we recommend that you start by walking slowly for 5 minutes, then at a moderate pace and then gradually accelerate before reaching your cruising speed. The first 5 minutes relax your muscles and help reduce the risk of stretching and straining At the end of the session, to avoid feeling dizzy from suddenly stopping physical exertion, slow down for 3 to 5 minutes.
