John O’Connor is a great teacher and we should know — we’ve been working out in a variety of gyms and studios, together and apart, for over thirty years. Johnny practices what he preaches, and leads by example. He sets the bar high, but helps you reach it, and helps you work your edge. He is calm and centered, so you focus on your own workout. We keep coming back for more! And we are in good company. Put us down as fans.
