You want to lose weight or gain muscle? Because muscle weighs more than fat.

You want muscle, sign up to your local YMCA, get a protein supplement from your local pharmacy if you want, exercise a different section of your body every day or every other day (abs and legs on one, chest and arms on another, and keep it good and switched up with back and such so you don't have a routine, so your body is confused and can't compensate fast enough to make sure you don't rip those muscles good enough --- you get bigger muscles when you rip down the old ones and the body builds better, bigger muscles that can take more). Check out some workout sites and such as well, perhaps static training would be good for you --- it doesn't work on muscles really, but it works on giving you hellaspeed. It's what Bruce Lee did.
