We’re all concerned about bikini bottoms. ALL OF US. But when you’re bogged down with work all day, sometimes you only want to curl up and tune out for a while. Well, good news, you can do that and tighten up your tuchis. It’s another lazy day workout. So turn on Tivo and get ready to tone. After the thrusts, do each side for at least 5 minutes. About a minute per movement.
