Interval training works by alternating short bursts of explosive activity, followed by a short rest, allowing you to get the same cardiorespiratory benefits of a longer, medium-intensity workout in less time. Because they're fast-paced, they're also pretty fun — and in the 30-minute HIIT workout category, there's a lot of versatility, from low-impact workout options to weighted high intensity interval training classes.

We've rounded up a collection of 30-minute HIIT workout videos on YouTube that can be performed at home. The instructors provide clear and easy to understand instructions, keeping you feeling motivated and supported throughout the class. Most classes include modifications, as well, which make the exercises in the class modifiable and beginner friendly.

Grab your favorite yoga mat and pair of sneakers, pick a 30-minute HIIT workout that sounds interesting, and press play. If you need added motivation to work hard, keep your mind focused on the post-workout sense of accomplishment that's surely waiting for you once you're done.
