About Katalyst

The Katalyst App is the companion to the Katalyst Suit, a wearable training system powered by advanced fitness technology. Together, they deliver a full-body workout no app can deliver on its own. A Katalyst Suit is required to train. The Katalyst Suit is an FDA-cleared, patented system that uses Electro Muscle Stimulation (EMS) to engage your major muscle groups at once. Low-frequency impulses mimic the signals your brain sends to contract a muscle. Pair them with simple bodyweight movements and every rep works harder, engaging up to 90% of your muscle fibers, including the deep back stabilizers most workouts miss, with zero load on your joints. ALREADY HAVE A KATALYST SUIT The app is free. Log in or create your profile for unlimited access. NEW TO KATALYST Explore the app and preview the workouts. Get your system at katalyst.com.
