I agree to search you tube. There are beachbody users who have posted videos of themselves doing the workouts. it can help you get a feel for the different programs to see if they will interest you.
slim in 6 is a great program, especially for beginner to intermediate workouts. You will lose weight and get smaller.
Since you are a guy, I would also look at Power 90 (the prequel to P90X), P90X (if you have time and can commit to the challenge), Les Mils Pump, 10 minute Trainer. I personally did not like RevAbs but some people have gotten good results.
I am finishing Les Mils Pump right now and Love it. I was impressed with their beginner workouts - they were very knowledgeable and informative. My husband has just started Pump after watching me and has lost 10lbs in 2 weeks

good luck!
