20-Minute HIIT Workout

20-Minute HIIT WorkoutOh joy. More snow.

I love living in a place that sees all four seasons, but man do snowstorms get old quickly. The first snowfall of the winter is always exciting, but with parking bans and frozen pipes and icy sidewalks, the white stuff quickly loses its charm.

If you’re snowed in today like we are in Boston, skip the hike to the gym and do this 20-minute HIIT workout right in your living room. I did it yesterday and loved it—got my heart rate up, and my legs were toast by the last round of snowboarders.

20-Minute HIIT Workout

Equipment I Used:

Set an interval timer for 20 rounds of 45 seconds of work and 15 seconds of rest. You’ll go through the following set of exercises four times.

As a great way to challenge yourself, keep track of how many reps of each of the five exercises you do during the first round. On the fourth and final round, try to match those rep numbers. I couldn’t do it for the side-to-side plank jumps, but just having that goal number helped me push myself harder than I normally would have during the last round.

20-Minute HIIT Workout

  • Jump Rope
  • Side-to-Side Plank Jumps: Start in a plank position. Jump both feet up towards your left hand, landing on your toes (to protect your knees). Next jump back into a plank position and then jump both feet up towards your right hand. Continue back and forth as fast as possible.
  • Alternating Lunges with Shoulder Press: Holding a dumbbell in each hand (I used 8-lb weights), stand up straight, feet shoulder-width apart, weights at shoulder height. Lunge forward onto your right foot, both legs bending at 90 degrees. As you step forward, press the weights up over your shoulders, bringing them together above your head. Pushing off that front foot, come back into a standing position, lowering the weights. Repeat on the other side.
  • In-n-Out Full-Body Crunches: Start sitting on your tailbone, leaning back, hands on the ground lightly behind you for support. Crunch your knees in to your chest,bringing your torso forward to meet them. Extend legs back out, keeping them a few inches off the ground. When fully extended, separate them, bringing them out to the side while keeping them straight. Bring them back in together and crunch knees back in. Feet should stay off the ground the whole time.
  • Snowboarders: Legs wide apart, squat down with one hand touching the ground. Jump up, turn 180 degrees in the air and land in the same deep squat on the other side, with the opposite hand touching the ground. If you turned towards your right shoulder the first time, make sure to turn towards your left shoulder on the way back.

    Yep – 2nd snow day in a row – workout, phone calls and 3 hours worth of Monopoly!!!

  5. I love all of your workouts. Can’t wait to try this one!

  6. I must tell you how much I enjoy your workouts (well you know what I mean!). No snow day here in sunny FL!

  7. Literally just had to try out a snowboarder to see if I could do it… check! (just!) Will definitely try this one. TY for sharing it!

  8. Love this! Pinning this so I can try it this weekend 🙂

  9. Did this yesterday morning, burned 170 calories. Thank you for putting these effective workouts together.

  10. Where did you purchase your jump rope? Have you found it to be pretty durable? Just asking because I’ve made a couple of jump rope purchases which were both major fails. The last purchase literally fell apart and disintegrated with every jump, so I’m definitely in the market.

  11. I tried this earlier today because I didn’t want to drive in the cold to the gym! Those side-to-sides were killllller.

  12. I love HIIT work outs! Thanks for sharing!

  13. Woo! Just did this 🙂 I love creating my own workout routines too, but there are some mornings (like today!) when I want to try a workout from someone else!! This was def something quick and I am ready to start my day 🙂

  14. I got through it! Snowboarders were tough but somehow didn’t stop till I finshed. I love that your workouts make me feel like throwing up, really dizzy but really accomplished after I finish. That’s what I call a good workout.
