"Wall sit" Matt Furey Style to strengthen the legs, tighten the mid section and improve posture!
Perform the wall sit in this manner and you will work your legs, calves, tighten your midsection, improve your posture and strengthen your upper back! I learned this style of wall sit from Matt Furey and definitely recommend his materials! Long holds don't just train endurance, they will make you stronger and build muscle size as well. Enjoy the burn!
