I've done supreme 90 (90 day workout) it worked pretty good
Plus running and using the weights at home/gym will help.
There is also P90X or T25 if you like using workout dvds. I would try to find them used because they cost a bit.
I myself have just started the Insanity workout. So far it's really good.
Don't forget to eat right and drink a lot of water!
Yeah I know people say it all the time but you'd be surprised how many people don't. Then they turn around gettin all mad because they never got fit or lost any weight. Lol
