One thing I recommend doing to add to your repertoire of bodyweight exercises is to go out and buy one of those pull-up doohickeys you insert in your doorjamb. Or, if you’ve got a tree with a sturdy branch in your backyard, that’ll save you thirty bucks and a trip to Dick’s or Sports Authority.
But for the sake of this post, we’re going to focus on HIIT (High Intensity Interval Training) workouts that will leave you sucking air and feeling badass. I also like to call this the “oh shit” workout, because that’s what I utter between sets when I feel like I’m about to collapse. All you need is your body, a little space, and twenty minutes or less to complete these circuits.
