Ok now this is gonna sound really dumb and stupid and your gonna get people say don't do it listen to me and blah blah blah, but If you want to exercise at home go out and buy a nintendo wiii and wii fit. I've been using it for a couple of months and i'm feeling healthier and am a lot more toned now, and i'm only a little person. It will help strenghten your muscles and tone them as well without bulking up. And if your like soreness do the exercises on wii fit properly with multiple reps and you will hurt. Trust me I was hurting for a couple of weeks.
