Whether you’re stuck inside, you’re on the road, or you absolutely can’t stand pounding the pavement, you’ll love this no-run cardio complex.

Men’s Health Fitness Director calls it the “squat jackup,” and it consists of three bodyweight exercises—the jumping jack, the squat, and the pushup. Watch the video above to see how it’s done.

Each exercise works your muscles in different ways. That means fatigue won’t overtake you, so you can keep the intensity high the entire time, Gaddour explains.

“Your heart rate will go up and up every minute, which is what you need to burn calories and get in great shape,” he says.

Here’s how it works: Perform a movement for five to 10 seconds, and them immediately flow into the next exercise. Do this for two to three minutes straight, and then rest one minute. That’s one round. Do five to 10 total.

And if you want to make it even harder, add skater jumps after the jumping jacks and mountain climbers after the pushup.
