The Barre method is a very effective form of exercise that enlists your own body weight, light weights, and a ballet barre as resistance. It is done using very small, deliberate movements to bring specific muscle groups to a state of fatigue. This specific way of working the body leads to tremendous overall strength, core stability and a long, lean body. There is a beautiful balance between strength and flexibility in a Barre class, making it one of the most efficient workouts out there.
