A groin injury can keep you off the field, and even off your feet, for several months. The groin is so important and interconnected to the muscles of the abdomen and legs that there is almost no way to recuperate quickly if you hurt it.
Every sport and every kind of physical activity uses the groin. No wonder your lower energy center sits right on top of it!
You should do this stretch before any kind of extended physical activity. Even though you usually hear about male athletes getting groin injuries, it is just as likely in women, so no matter who you are, you need to stretch your groin!
