I'm four months out from my wedding, and I would still like to lose a few inches from my butt/thighs and tighten up my lunch lady arms.  I've been on a healthy low calorie diet and adding moderate exercise to my routine since August and managed to drop 20 lbs, which included 5 inches from my waist and an inch from each thigh but not a centimeter from my butt!  
I want to do one of those intensive 30 min workout videos, but I know I probably won't be able to keep up with it daily for four months.  I would love suggestions on which video to try (especially those focused on butt and arms) and when to start the super-intensive workout regime so I don't have time to get flabby again before the wedding.  Right now I'm thinking starting the first week of May for my last week of June wedding.
