So, I'm due in May but I want to workout now. I don't really eat too bad but I have gotten lazy when I started work in October. I had to resign due to lifting restriction and bad cramping the second week of January. I have been taking it light because of that and because of my past but have been cleared for light workouts. So my question is what are some that I can do at home (not allowed to go far incase of something happening) and that you've done or know of? Please, I'm going nuts with nothing to do but sweep mop and scrub floors (only taking up about 3 hours of my day if I'm lucky).
