This is actually a very good decision, because many athletes who are not allowed to do heavy sports for health reasons, start doing lighter ones, such as stretching, yoga and so on, and get a lot of benefits from it. Ift talk about stretching, it really has a lot of them: it preserves joint mobility, increases muscle strength, accelerates blood flow to the muscles, thereby improving metabolic processes in the cells and relieving swelling. In general, your body will only thank you for the fact that you have not completely abandoned sports, and still continue to do them, but in a lighter version.
