Yes. In fact, I was starting a routine where I did my physical therapy, and I had to stop so a stress test and a doppler of my legs were done. Those came back ok, so I am returning this week to exercise using the machines to help build strength in my lower body. I agree, water physical therapy is a great way to exercise, too, and I hope to get into that very soon, too. I stay so busy that I need to say no to some things and do more for myself.
