i'm pluggin away at cardio, but seriously only the wall of fat on my midsection is holding me back from looking extremely cut. I was wondering if any of you guys have used any of the fat loss stuff out there, xenadrine, hydroxycut etc, and if you had good experiences with them- loss of muscle, any other problems? some guys at the gym swear by them, but when i ask how much the weight they lost was muscle andw ater, they have no response....just wonderin.
