Sprints, burpees, squat jumps, and other staples of high-intensity interval training (HIIT) are undeniably challenging. But HIIT workouts burn a ton of calories, and I know I always feel so good when I'm finished — that is, after a few days of super sore muscles. If you're also a fan of HIIT, then you have to check out these 30-minute HIIT workouts on YouTube! You can do these heart-pumping, calorie-burning workouts anywhere, whether you prefer to work out outside or in your tiny apartment. Just put on some leggings, blast your favourite workout music, grab some weights and water, and press play.
