An important area to train is your mid-Section. People often refer to it as the core. The reason I believe this is so important is that no matter what you do, your core plays a major role in every single thing we do. Walking running sitting working you need to have a strong core otherwise your lower back may become sore through over work.
The campers here have a fantastic way to learn how to strengthen their core. they are learning how to switch the core on when they need it. To find out what they did ask us.
