So I ask my doctor about half a year ago about stretching like what you do on a yoga though Im not planning on doing yoga and they told me not do it or yet im not sure I cant quite remember but this was when I had my pacemaker for about 1 year and the doctor that told me this is my new doctor since my old doctor is for children and since I just turned 19 they put me with the new doctor. And I want to know if this kind of stretching in the youtube link at top is allowed for me. Im planning on asking my doctor but there still a month before my next check uo and I dont have their number. I recently started doing push up variation and some cardio exercise that target my lower and upper body and I think stretching is important for exercise. So should I just do it or wait for my check up?
