It's time to get used to that old kettlebell lying around the gym, because it's your new favorite workout partner. Prepare to pick it up and never put it down—until the entire circuit is complete, that is.

Get warmed up with a starting round of kettlebell swings, but prepare to feel the burn in your legs with kettlebell squats and finally, single-arm kettlebell thrusters. You can thank this routine for not only toughening up your entire body, but strengthening your hip flexors, as well.

Directions

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

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