An array of individual trampolines await exercisers inside each workout studio at the popular Jumping Fitness—which features 700 studios worldwide—each ready to help jumpers burn calories, build lean muscle, and sweat up a storm in heart-pumping classes. In each instructor-led class, participants bounce along to the beat, sometimes holding onto a handle to intensify the workout and keep the core more engaged. While the low-impact workout goes easy on joints, it's not gentle on calories or fat.

When the sun sets the fun ratchets up, with a mini light show illuminating the studio. And on Friday evenings, jumpers gather for a Jump Party session on the trampolines backed by thumping beats.
