I take pilates at Fuse in Dupont and I LOVE it. It’s not classical pilates, but more of a fusion of yoga, barre, pilates. Although the reformer classes are mostly all pilates. The instructors are great and will help you to modify just be sure to let them know what your injuries are. The reformer classes have max 7 people so you get pretty good individual attention. There are also private classes if you are interested in that. I would say having taken pilates at several places that the quality of instruction you get at a studio is far superior to a gym so I would go a studio if you can.
