In the Olympics, the higher they soar on the trampoline, the better. During this workout, the opposite is true.
"You don’t jump on it. You load down," says personal trainer Irene McCormick. "So you pretend there’s a ceiling over your head and every time you jump, you actually push down into it."
McCormick says there's been a reemergence of trampoline fitness, in part because of the cardio-vascular benefits. Research shows it's almost as beneficial as running - minus the impact on the joints.
"We need the high intensity training, but a lot of people can’t take the pounding of running or sometimes even walking," says McCormick. "I think you’ll find that it’s really a lot harder than you think."
After warming up on the trampoline, McCormick puts us through a series of Tabata drills.
"It’s an interval formula. It’s a two to one ratio," explains McCormick. "So you’ll work for 20 seconds and then you’ll recover for 10."
Loading down rather than jumping up engages the largest muscles in the body - the Gluteus Maximus, which as McCormick explains, is an important muscle.
"It's hard to engage it without actively thinking about it and on the trampoline, you will have to. You can't do the work."
Engaging the Glutes also pushes up the heart rate. As Irene predicted, this is harder than it appears - much harder.
"It looks so easy if you're watching someone else do it," says Erin.
In addition to the cardio-vascular benefits, there's also evidence the trampoline helps the lymphatic system. And better yet, it's fun.
"So if you don't like to exercise and it's not very fun for you to walk or run on the treadmill, this is a good option."
