I am 145 lbs so don’t think an issue…. But thank you…. I do aqua therapy use bike twice day for 20 min each time, along with other floor exercises…. There are times I have to take break because of swelling …,I had tkr dr put in wrong size so had revision within a year …. I do mfr along with chiropractor twice a week, …. Sometimes you can do all the exercises in the world still don’t get you desired outcome …. I am here not from lack of exercise , but I stay positive , giving up not in my nature lol …. But thank you for that suggestion I will check it out….
