They say three is a magic number, and in the case of this muscle-defining workout, that is most definitely the case.

Kick things off with a pair of dumbbell exercises—dumbbell clean and presses and renegade rows—to sculpt your upper body and core. Then, finish out the circuit with a round of mountain climbers that will give you a real total-body burn. Trust us, three moves is all you'll need.


Do each each exercise back-to-back-to-back, resting for 30 seconds only when you've completed the circuit. Repeat for 5-10 rounds.

Depending on your ability, you may shorten or lengthen the rest period. You may also complete more or fewer rounds.
