Katalyst removes the barriers to fitness to help you reach your full potential. We use proven electro muscle stimulation (EMS) technology to fully activate your muscles, delivering a complete, full-body workout in just 20 minutes, without any weights or wear-and-tear on your body. Easy to use, on-demand and travel-ready, Katalyst is the first and only product of its kind to be FDA cleared for consumer use.


High performance materials with integrated electrodes mapped to all your major muscle groups. Weighing ~3 pounds, the Suit is travel- ready and stores away easily when not in use.


Specially designed to retain moisture for optimal impulse delivery. The seamless knit, constructed from a sustainable Tencel™ blend, keeps you comfortable while you work out.


The heart of the operation, the Impulse Pack translates commands from the Katalyst App into precisely-tuned impulses delivered to the right muscle, at the right time.


A totally immersive fitness experience, with on-demand classes led by EMS trainers. As you work out, the App intelligently controls and personalizes your impulses in real-time.

Katalyst leverages electro muscle stimulation (EMS) technology to create an extraordinary new way to work out. Our patented training system and full-body suit deliver specially-tuned, low-frequency impulses to your major muscle groups. These impulses imitate the brain signals that cause your muscles to contract and multiply the results of any exercise when combined with simple bodyweight movements. The result is a 20-minute, full-body workout that engages up to 90% of your muscle fibers. To reach this same level of muscle activation hours of traditional exercise would be required. Katalyst provides:

  • An elite, full-body workout in 20 minutes.
  • All-in-one Strength, Power, Cardio and Recovery training.
  • Content delivered via our iOS app, curated by expert trainers.
  • Lightweight and ready to go wherever life takes you.
  • No weights or other equipment required.
  • No joint impact or injury risk.

Most muscle contractions occur when the brain sends a signal through your central nervous system to instruct your skeletal muscles to contract. These muscles come in pairs, one to move your bone in a particular direction, and the other to move it back. Unlike internal organs and cardiac muscles, skeletal muscles are voluntary, meaning that they require a trigger (such as a brain signal) to activate.

Full-body EMS devices combine the advantages of conventional strength training with EMS technology. Users wear a “suit” that maps a series of built-in electrodes to each of your major muscle groups. The low-frequency impulses that serve as the basis for EMS actively engage all muscle groups simultaneously, rather than placing single electrodes on individual muscle groups. With these impulses, the muscles are engaged much more intensively, multiplying the effects of any exercise.

Most likely! We created Katalyst to help all people improve their health and fitness. The Katalyst Suit and Base Layer are modular and able to fit a wide range of body shapes and sizes. After placing your order, we will contact you to collect a few measurements to ensure the optimal fit for you. If you are in doubt, feel free to reach out to [email protected] for pre-purchase sizing.

Katalyst is for everyone. Whether you want a competitive edge or to improve your fitness throughout life, Katalyst gives you an insanely effective workout without joint impact or injury risk.

Katalyst is intended for use by adults only. See additional Safety Guidelines here.

Do not use the Katalyst Training System if you:

  • Have a pacemaker (artificial pacemaker), implanted defibrillator, or other implanted metallic or electronic device.
  • Are pregnant.
  • Are experiencing extreme muscle strain or trauma, or if you are experiencing a muscle strain condition such as rhabdomyolysis.
  • Have been diagnosed with any heart problem or condition.
  • Have an inadequate blood supply (ischemia) or a serious blood circulation disorder in the lower limbs.
  • Have an abdominal or groin hernia.

As a medical device regulated by the FDA, there are certain claims we are not allowed to make and it applies to powered muscle stimulators in general. One of these claims is weight loss. We do not claim weight loss as a benefit, though we regularly hear from members that they have lost weight as a result of using Katalyst.

Katalyst helps you do more work in less time by activating 2x more muscle fibers than conventional resistance training. When lifting weights, approximately 45%-50% of muscle fibers are stimulated. With Katalyst, we are able to stimulate up to 90% of muscle fibers.

This is possible because the signal is generated externally (via the impulse), rather than internally (via your brain), making this form of exercise incredibly efficient.

On top of that, Katalyst is a true full body workout, activating all your major muscle groups simultaneously. Each 20-minute session gives each of your major muscle groups 10 minutes time under tension, equivalent to hours in the gym.
