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. WORKOUT MODES FOR EVERY LEVEL Programs built by professional trainers, from your first session to elite. - Strength: complete full-body strength in less time - Power: explosive sessions that recruit fast-twitch fibers - Cardio: lower-frequency sessions designed to build endurance, with quick recovery for daily use - Recovery: active and passive modes with massaging impulses to finish like the pros - Freestyle mode: Choose a mode, set your intensity, and train your own way. TRAIN LED OR TRAIN SOLO In guided classes, your trainer adjusts intensity in real time so you can focus on the movement. Prefer your own pace? Run independent programs on your terms. ALWAYS IN CONTROL Dial intensity up or down, or target a specific muscle group, at any moment. How hard you train is always your call. TRAIN ANYWHERE Stream any workout on demand, or download sessions ahead of time for when you'll be offline. BUILT FOR YOUR SETUP - Apple Watch: adjust overall intensity, pause, and resume workouts right from your wrist - AirPlay: put your instructor on the big screen and use your iPhone or iPad as the remote Get more strength and more out of life with Katalyst Suit workouts. katalyst.com
