GETTING MY FITNESS BACK IN GEAR.

If I am truly honest with myself once I get to the gym I like being there, and I love everything from Cardio (running on the treadmill) to lifting weights..and seeing a shift in my body.I actually love getting sweat, and feeling tired in every way. It not only helps my mood, but it also helps me sleep better, my skin clears up, and overall I feel much better about myself..So why can I not do it for more then a few months? That is the thing I have to figure out.
