P90X!!! my brother lost 25 pounds in 90 days and built muscle with their program. im joining the army so im getting it soon. In good shape but more muscle couldnt hurt. Its alittle expensive ... See more but you cant argue with the results. It even comes with a nutrition guide as well as tons of workouts. Never heard a negative thing about it as long as you know your limit! Hope i helped at least one person:)
