1. Strength and definition
When you work your thighs in a Barre Class, you target that muscle group from all angles. Three thigh exercises will work to fatigue the front, inner and outer thighs, strengthening the muscles from joint to joint. The same goes for your abs back glutes and arms. Use of your arms in Barre just holding in 2nd or port de bras is an excellent way to strengthen your shoulders as well as your back. You are also strengthening muscles that are often underused and underdeveloped.
