I've started working out for an hour each day, but I'm wondering if what I'm doing is considered working out. I raise my right knee to my left elbow, lower them, twist my body twice, then repeat with the opposite limbs continuously for an hour each day is this considered physical activity? I live in an apartment and on the top floor, I don't want to make noise and this is the quietest kind of activity I can think of please help all suggestions appreciated!
