Kandoo Rebounding doesn't let gravity interfere with a good workout. Instead, the instructors outfit students of all ages and fitness levels with Kangoo jump boots that create a trampoline-like bouncing effect with each hop. Their 50-minute classes infuse traditional aerobic workouts with the boots' rebounding capabilities. The result is a low-impact exercise regimen that manages to be relatively easy on joints as students engage in familiar cardio and strength-training routines. Over time, Kandoo Rebounding's fitness and boot-camp sessions build stamina, core stability, and power while generally improving balance and coordination.
