I started pump & pilates etc 3 weeks after c section, but did modified moves, nothing that pulled or stretched the area of my scar. Doc & instructor were both fine with it as long as I took it easy, did the modified moves and listened to my body if anything didn't feel right. I had been doing pump & weights right up until a few days before birth so it wasn't hard to get back into it. I think you'd be fine to give it a go, just listen to your body
