If you want to stay and get healthy make sure you learn about soft tissue mobilization. There are many tools that you can use for soft tissue mobilization. Foam rollers are an inexpensive tool that can be used. Mobilization of soft tissue is as simple as getting a foam roller or another tool and using bodyweight to apply pressure to sore spots, a form of self acupuncture. Using the foam roller before stretching makes the tissue more pliable and extensible, the key is to search for tender areas or trigger points and roll those areas to decrease tissue density and overactivity.
