Join fitness trainer Jake DuPree for an intense 30-minute upper-body workout that will help you carry all of your groceries in one load the next time you go shopping. You'll start with arm swings and work your way up to mountain climbers, tricep dips, jumping jacks, lateral raises, and so much more. Prepare to feel your arms burn! To get started, all you need is a mat and a medium set of weights.
