Whether you've given up on your New Year's resolution to bulk up or you've simply gotten lazy, now's the time to get off the couch and back into the gym.

And if you're not sure where to start, we've got a solution: This full-body, mass-building workout that's pretty much guaranteed to jumpstart your fitness goals.

Take on 10 rounds of this punishing routine—back-to-back walking lunges, single-arm rows with partial lunges, and alternating shouder taps—and you'll be well on your way to becoming that ripped guy at the gym.

Directions

You'll do this workout as a circuit, meaning you'll complete each exercise consecutively without rest. Once you've finished all exercises, rest for 30 seconds. Repeat the entire circuit for 5 to 10 rounds.

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