Frequently Asked Questions

General Experience
What is Katalyst?

Katalyst is a full-body Electro Muscle Stimulation (EMS) home fitness product. Utilizing proven EMS technology, our system actively engages all major muscle groups at the same time, providing a high-intensity, zero-impact workout in just 20 minutes or less.

The suit is controlled by the Katalyst iPad app, which streams curated, trainer-led workouts, providing an intense and highly efficient full-body workout that you can feel immediately. The workout is low-impact and suitable for adults of all ages and fitness levels. With just two 20 minute sessions a week, individuals of all fitness levels and body types can see and feel results within a few weeks.

How long is a Katalyst workout?

A typical Katalyst workout takes 20 minutes, ranging from a 5 minute recovery session to a 20 minute strength workout.

What muscles does the Katalyst System activate?

Katalyst is a true, full-body workout that stimulates all major muscle groups (arms, legs, back, chest, core, glutes) at the same time. The Katalyst impulses engage twice as many fibers within each muscle as you could with conventional training.

Do I need weights or other gym equipment to use Katalyst?

With Katalyst, everything you need comes in the box. You can optionally add small weights to increase the intensity of your workout, but it is not necessary in order to achieve an impactful EMS workout. For cardio workouts, you can optionally combine Katalyst with other equipment such as a treadmill or elliptical. The Katalyst Training System works with your body by amplifying your natural ability to engage your muscles. The result is a true, full-body workout that engages twice as many muscle fibers as you could on your own.

Who can use the Katalyst Training System?

Katalyst is for everyone! No matter where you are on your fitness journey, and no matter your training history, we can help you achieve your fitness goals.

Note: Katalyst is intended for adult use only and must not be used by pregnant women and those with pacemakers. Please see the Katalyst Instruction Manual for additional information.

Do you have my size?

Yes. We created Katalyst to help all people improve their health and fitness. The Katalyst system is modular by design and able to fit a wide range of body shapes and sizes. If you are in doubt, get in touch contact support@katalyst.fit.

Can two people work out together?

Yes, but each Katalyst user needs their own Impulse Pack and iPad. If two people want to work out side-by-side, it's best to buy two complete Katalyst Training Systems. We do not yet offer group training.

Do I need an iPad to do Katalyst?

Yes, the Katalyst Training System requires an iPad that is capable of running iOS 13 or later.

How often do I need to charge my Impulse Pack?

You can typically get 10+ workouts on one charge of your Impulse Pack.

Can I wash my Katalyst Suit?

The Katalyst Base Layer is designed to absorb moisture and perspiration during your workout, and to be washed with regular detergent after each use.

To ensure the longevity of your Katalyst suit, we recommend hand washing with cold water and mild detergent and infrequent machine washing. The suit is designed to be machine washable with cold water and mild detergent; however, it is possible that repeated cycles may eventually accelerate wear and tear on the suit. Do NOT place your suit in the dryer, as this will damage it. Always air dry your suit after workouts.

I have used a miha bodytec EMS device. How does this compare?

Miha bodytec, X-body, E-fit, and others have been building full-body MS training equipment for 10 and more years. They enable an industry of more than 12,000 personal training studios worldwide. While they are similar in their ability to train the human body, they are very expensive (around $20,000 per system), complicated to maintain (can’t be washed without disassembly), and require a certified personal trainer to operate. With Katalyst, you will get the benefits of personal training in a studio in your home for a fraction of the cost.

Why is Katalyst a medical device?

The U.S. FDA is regulating powered muscle stimulators as Class II medical devices. However, outside the U.S., they are considered consumer electronics similar to an electric toothbrush or hairdryer.

Is Katalyst cleared by the FDA?

Yes. Katalyst has actually received three FDA clearances in the past four years. The first clearance, in 2017, was an Rx-only (prescription) clearance for our first-generation device to operate our studio-based business model. The second, in 2018, was related to our second-generation studio device. The third clearance received in early 2020, gave us the ability to market and sell the Katalyst Training System, designed for at-home use, over-the-counter (i.e., directly to consumers).

When will I be charged for my purchase?

With non-financed purchases, we charge the full amount at the time of purchase. You will receive emails regarding suit sizing and shipment timing following your purchase.

Please contact support@katalyst.fit for more information.

What is your return policy?

All returns must be made within 30 days of purchase to initiate a return request. To return your product, please contact our member specialists at support@katalyst.fit.

Since Katalyst is a medical-grade product, for the safety of our customers we cannot resell any products that have been shipped to our customers. So, in all cases, we will deduct a 20% restocking fee for all returns. All returns must be shipped with the original packaging. Katalyst is not responsible for packages lost in transit without proof of tracking. Refunds for purchases will be credited back to the original payment method.

To guarantee the best EMS experience, we're determined that your suit should fit you snugly and comfortably. As a result, our sizing process ensures that your suit will be the correct fit. This removes the need for most returns. In the unusual event you need to exchange part of your Katalyst Suit due to sizing or quality concerns, please contact support@katalyst.fit for assistance.
