I believe that yoga exercises and in the gym will help to increase muscle mass. Yoga will help you to stretch your body well, strengthen your joints. The gym will build muscle and give strength in the arms. I prefer the gym more, but my physique and metabolism did not allow me to get the shape I wanted, so a friend advised me to use YK11. I asked sarmguide.com here that this is a steroid that will increase muscle mass and strengthen bones, and this is exactly what I needed, but I advise you to read about it in more detail to avoid side effects. it is advisable to consult a doctor for advice.
