This workout from NASM-certified personal trainer Nicole Pearce includes progressions that will add exercises together to make them "combos," and then take moves away to work on individual exercises. For instance, you'll do twisted push-ups, then add on thread-the-needle pikes, then end with just thread-the-needle pikes. The progression concept in this 12-minute session may seems a bit daunting, but Pearce explains it all in the beginning.
