I hope he gave you light weight bearing not too heavy at first. Reason is it helps strengthen the bones too. They have these pedal machines I found on Amazon. Portable without a bike and can exercise while sitting down in front of the computer. I got one for one of my grandsons because the doctors were going to rush and do surgery on his legs but after tests they couldn’t figure out what was wrong. I told my daughter in law I think I know what was wrong. He has independent study. He gets his work done fast then does interactive video games. Now he’s learning the stock market. Too much hours sitting . They can get clots that way too. Now he uses it when on the computer, problem solved. It has different resistance levels. There’s ones as low as in 30 dollars. Hope she passed that to the doctor as more and more are pulling kids out of public schools especially since Covid.
You don’t have to do them every day you can do them 3/4 days a week but maybe try to do stretching exercises when you get up. Muscles can start to atrophy pretty fast so if not active passive range of motion. Your walking well now and have years to go, you don’t have to turn into muscle man all at once. Lol
