Sure, you can schlep to the gym and hop on the elliptical for 45 minutes. Or you can lace up your sneaks and head outside for a long run to turn up your heart rate and calorie burn. But when the temperatures drop or you just don’t have time to leave your house, you can still squeeze in a solid cardio workout at home. All you need is a little room to move—and the ability to push yourself, just enough so your heart starts pumping and the sweat starts flowing.

How can you do that? Two words: plyometric exercises.“[These] exercises are perfect for a cardio workout at home, as they save space (all the movements can be done in one place) and time because it requires max effort—and thus, less overall time spent—while also offering strength, power, and cardio benefits,” Judine Saint Gerard, NASM-CPT, head coach at Tone House in New York City, tells Health. “With these added benefits of strength and power, it may be even better than just trotting away on the elliptical.”

The key to working hard enough to reap all the fitness rewards: firing up your core temperature so you start dripping sweat. “Most cardio workouts produce heat in the body—the more strenuous the workout, the more heat it produces, and sweating is the body’s way of cooling down,” she says. If you work through a cardio workout at home and finish it sweat-free, you’ll want to power up your intensity on the next go around. That means working faster or taking fewer breaks.

If you need a cardio workout to kick off your at-home training, Saint Gerard has the perfect routine for you. Here, she offers 10 plyometric exercises, plus how to time them to your heart-pumping advantage. Each one also has a low-impact variation for anyone jumping back into fitness after a long hiatus or someone who's starting a regular exercise routine for the first time. They're also smart options for those with injuries. The only thing you have to remember is to work hard so you end in sweat—so don't be too easy on yourself.

The Workout

If you’re opting for the high-impact plyometric moves, do each exercise below for 30 seconds, and rest for 30 seconds between each exercise. Prefer staying on two feet and skipping the jumps? Follow the modified moves for 30 seconds each, with just 15 seconds of rest between each exercise. Do 2-3 rounds with 60-90 seconds of rest between each round. The best part: the more you practice the less rest you’ll need.

Mountain Climbers

1. Start in a plank position, shoulders over wrists, forming a straight line from shoulders to heels.

2. Keep core tight and back flat. Drive one knee in toward chest, then place it back down.

3. Immediately drive the opposite knee in toward chest. Then, place it back down. Continue alternating.

Modification: Eliminate the hop and slow down your pace, still driving one knee at a time in toward your chest.

Vinyasa

1. Start in a plank position, shoulders over wrists, forming a straight line from shoulders to heels.

2. Lower down as if you’re doing a push-up, keeping elbows tight by sides.

3. Then, move chest through arms, coming into a cobra or up-dog pose (slight arch in the back; chest toward the sky).

4. Next, push through hands and lift hips all the way up to a downward-facing dog position. Repeat, flowing back to a plank position.

Modification: Drop the knees while you lower into a push-up position for more support.
