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.

Absolutely. At checkout, you can select Affirm as your payment method to pay over time. Terms and conditions apply.

Companies such as Miha bodytec, X-body, E-fit, and others have been building full-body EMS training equipment for 10+ years, primarily for a studio-based, B2B market. While these devices are similar to Katalyst in how they train the human body from a scientific perspective, they tend to be very expensive ($20-50,000), cumbersome to maintain, bulky to transport, and require a certified, professional trainer to operate. 

 Katalyst is the only full-body EMS device to be FDA-cleared for consumer use. In contrast to other devices on the market, we built a premium consumer fitness experience that is incredibly easy to use, lightweight, and travel-ready, with on-demand training content delivered straight to your iPad. With Katalyst, you get the world’s best full-body EMS training anytime, anywhere, and for the price of a Peloton. 

Please see our FDA 510(k) clearance document here.

While we recommend that you do not share your suit with others, we also do not restrict use. If you do share your suit, we require that a) it fits properly, b) the person you are sharing with does not meet any of the health restrictions noted in our Instruction Manual, and c) they create their own account in the app. This ensures that they agree to the Katalyst terms & conditions, and that they do not override your personal workout intensity settings.

Katalyst offers a one-year limited warranty on the Suit and accessories, and a three-year limited warranty on the Impulse Pack. The warranty covers manufacturer-related defects, and not defects arising from normal wear-and-tear, misuse, etc. The longevity of any product largely depends on how it is cared for, and the Katalyst Training System is no different. Care instructions can be found in our Instruction Manual, and our warranty is available here.

Our return policy is available here.

Weights or other gym equipment are not required to use Katalyst, because EMS amplifies your natural ability to engage your muscles without the need for any external loading. 

For cardio workouts, many customers have had success combining a Katalyst session with other equipment such as a treadmill, elliptical or assault bike.

We offer memberships in 1-, 2- and 3-year increments. A monthly membership option is available after the initial term ends.

The cost of a Katalyst membership ranges from $29-49 per month, depending on subscription length. Members can pay up front via credit card, or pay over time via Affirm.

Katalyst memberships are tied to Impulse Packs. If you have two full Katalyst Training Systems, and therefore two Impulse Packs, then you would need two memberships. If, however, you have one Impulse Pack and two suits, then only one membership is required.

Katalyst memberships are tied to Impulse Packs. Each Impulse Pack has one membership “holder” for billing purposes and up to 4 user accounts.

Your Katalyst membership will activate on the date of fulfillment. However, we allow an extra 30 days from the fulfillment date to ensure ample time for shipping, delivery and onboarding.

If you paid upfront via credit card, your membership will auto-renew at $49 per month after the initial term. You can visit the customer portal to upgrade or change your membership.

If you financed through Affirm, as you approach the end of your membership term, we will notify you of your renewal options.

If you need to pause your membership, please reach out to  and we would be happy to work with you.

You can cancel your membership by visiting the customer portal. After canceling, your membership will remain active through the last date of your paid subscription. For example, if you purchased a 1 year membership, it will remain active through the 1 year anniversary of your membership.

If you initiate a return within the 30-day return window, we will refund the full amount of the membership to your original payment method. For more information on our return policy, please visit katalyst.com/returns.
