THE WORLD’S MOST EFFICIENT WORKOUT The Katalyst App is the companion to the Katalyst Training System, a revolutionary new workout that uses Electro Muscle Stimulation (EMS) to engage all of your muscles simultaneously. Our patented training system and wearable suit, controlled by the Katalyst App, delivers specially-tuned, low-frequency impulses to each of your major muscle groups. These impulses imitate the brain signals that cause your muscles to contract and, when combined with simple, bodyweight movements, multiply the results of any exercise. The result is a complete, full-body workout that engages up to 90% of your muscle fibers in just 20 minutes, even hard-to-reach back stabilizers. And because Katalyst does the heavy lifting for you, there is zero load added to your joints. HOW TO JOIN & ACCESS THE KATALYST APP New to Katalyst?
