Using fats to get fit So the other day I was at a different gym out of town from where I usually workout. They had tires laid out with sledgehammers that you hit the tire with. So I decided to do that for a while after I was done lifting. So of course I'm imagining it's an obeast that I'm hitting with the sledge, and next thing I know I've been at it for over an hour. Anyway, long story short how do we make this dream a reality?
