To lose weight I am using a walking/jogging/and sprinting combo about 5 miles a day for some cardio. Then lifting weights in my garage using lightweights with high reps and little rest between sets going from one body part to another. Maybe in another month I will join a gym and go to heavy weights and low reps, but right now just trying to get in better condition.
Also key is watching your calories of course. Losing around 11 pounds a month right now.
