Kettlebell and Band Upper-Body Workout 

Any respectable garage gym ought to have some kettlebells or bands—two types of equipment that, on their own, can cover pretty much any training goal and any kind of workout you choose to try. But combine bells and bands into one routine? You must be mad…

The following workout is brought to you by one of our favorite mad scientists—the Onnit-certified Eric Leija—who came up with it while experimenting in his own garage gym. The routine requires only a pair of moderate-weight kettlebells and a light resistance band and trains your chest, shoulders, arms, and upper back muscles in under 30 minutes.
