Real men Use the Bosu. I know it looks like a giant blue boob. But try this: flip it over, do a push up and when come up pull the Bosu to your chest, stand up and repeat. After doing 10 do 10 pullups as well. We did this after an hour in the Austin sun doing kettlebells,pushups,hurdles and weighted jumping jax. It's all about finding new ways to push yourself. Give it a try.
