You Won't Believe How Sore This 16-Minute Bodyweight HIIT Workout Will Make You

If you're short on time but want to get in a good heart-pumping, muscle-building workout, HIIT (high-intensity interval training) is where it's at. These workouts will not only burn calories, but they're proven to diminish belly fat.

This 16-minute HIIT workout involves eight basic bodyweight moves, many of which are plyometric exercises. During each 45-second intense interval, give it your all to really maximize the calorie-burning, belly-fat-melting effects of HIIT, knowing you'll get a 15-second rest to recover.

Mountain Climbers

  • With your core engaged, bring your right knee forward under your chest, with your toes just off the ground. Return to your basic plank. Switch legs, bringing your left knee forward.
  • Keep switching legs and begin to pick up the pace until it feels a little like running in place in a plank position.
  • Continue "running" in your plank for 45 seconds. Take a 15-second rest.

Dolphin Dive

  • Begin in Quarter Dog with your forearms parallel. Press your hips and shoulders back toward your feet, lengthening through your spine. Tilt your tailbone up slightly to feel a stretch in your lower back.
  • With fingers spread wide, take a deep breath in, and as you exhale, dive forward, lowering your chin so it's barely touching the floor in front of your fingertips. Your shoulders should hover over your wrists, and your elbows should remain in line with your middle fingers.
  • Inhale, and press back to Quarter Dog.
  • Keep going for 45 seconds, then rest for 15.

Hip Raise With Leg Extension

  • Lie on your back. Rest your hands by your sides, palms facing down, or place your hands underneath your butt for a little leverage.
  • Extend both legs out so they are a few inches above the ground. Draw your lower abs in, pressing your lower back into the floor.
  • In one fluid motion, bend the knees into the chest, press the hips up as high as you can, lower your hips to the floor, and extend the legs straight out.
  • This completes one rep.
  • Do as many reps as you can in 45 seconds, then rest for 15 seconds.
