This blog compares two popular whole-body EMS systems for personal use: Katalyst and Visionbody. Both systems offer unique features tailored to different user preferences, from convenience to guided workouts. This review provides an unbiased breakdown of the pros, cons, and ideal users for each system, helping you make an informed decision.

Katalyst vs. Visionbody: WB-EMS for Personal Use

At the time of this writing (2024), in the U.S., there are only two options to train with whole-body electrical muscle stimulation (WB-EMS) on your own. Based on insider sources, the landscape will soon change, but for now, it’s a Coke vs. Pepsi situation.

The contenders for your wallet are Katalyst and Visionbody.

Full Disclosure

I don’t use either system for professional purposes, so my opinion is strictly for personal use. I own a Visionbody suit and will explain my choice below. Additionally, I’ve only tried the third-generation Katalyst suit, though they’ve recently launched the fourth generation (the suit functions similarly).

General Notes

Both Katalyst and Visionbody are FDA-cleared WB-EMS systems, and their prices for equipment are similar. However, Katalyst requires an annual membership. Since both systems effectively deliver the benefits of EMS technology, this review won’t delve into the advantages of WB-EMS itself. Instead, it focuses on the features, pros, and cons of each system to help exercise enthusiasts choose the best fit for their needs.

Katalyst EMS System

Concept

Katalyst positions itself as the “Peloton” of EMS fitness. You purchase the suit and follow prerecorded classes via an iPhone or iPad (currently, it only supports iOS).

Katalyst EMS Suit Features

• Material: Durable, sleek, and uses magnetized cable connections.
• Adjustable Fit: Includes straps and buckles for accommodating slightly different body types.
• Connection Design: Cables connect at the front for easy setup.
• Usage Requirements: Requires water to conduct electricity through the body, like most EMS suits.

Components Needed for Katalyst:

• iPhone/iPad
• Arm bands (2)
• Jacket and pants
• Top and bottom undergarments
• Spray bottle (for water)
• Towel
• Disinfectant sprayer (for after use)

Technical Specifications:

• Maximum frequency: 105 Hz
• Maximum pulse width: 375 μs
• Strength setting: Capped at 75 Hz (most EMS studies use 85 Hz for strength)

Online EMS Training with Katalyst

One standout feature is the system’s ability to gradually increase stimulation intensity during workouts, accommodating your body’s adaptation throughout the session. The Katalyst app offers a library of recorded workouts, including strength, endurance, recovery, and sport-specific sessions.

Summary for Katalyst

Pros:

• High-quality, adjustable suit
• Guided video workouts
• Automatic intensity adjustments

Cons:

• Requires a membership
• Requires water and undergarments
• Numerous components make it less convenient for travel
• Undergarments and the suit need regular cleaning

Who is Katalyst For?

• People who want guided workouts.
• Those comfortable managing multiple components.
• Individuals who struggle with warming up or getting sweaty before exercise.

Visionbody EMS System

Concept

The Visionbody suit is a single-piece design that zips up the back, similar to a wetsuit. It uses a dry, sweat-activated system controlled via a simple app (iOS only).

Visionbody EMS Suit Features

• Material: Stretchy, rubbery material. However, electrodes may not align perfectly for non-average body types.
• Dry Activation: The suit doesn’t require water but needs you to warm up or sweat first. Improper preparation can cause a stinging sensation.
• Simplicity: No undergarments, water, or additional accessories are needed—just the suit, battery, and iPhone/iPad.

Technical Specifications:

• Mixed frequency range: Up to 100 Hz (low) and 2000 Hz (medium)

Online EMS Training with Visionbody

As of this writing, Visionbody lacks an official video library, though one is reportedly in development.

Summary for Visionbody

Pros:

• Dry suit—no need for water or undergarments.
• Minimal components, ideal for travel.

Cons:

• Requires extensive warming up or sweating beforehand.
• Limited adaptability for non-average body types.
• Suit lifespan: Approximately 100 washes (about one year with twice-weekly use).

Who is Visionbody For?

• People who know how to exercise or prefer following free YouTube workouts.
• Those comfortable warming up thoroughly before use.
• Frequent travelers seeking a convenient EMS solution.

Unanswered Questions

1. What happens if the company closes?
   • For Visionbody: The suit should still work as long as the app remains functional.
   • For Katalyst: Functionality depends on continued app and video library support.
2. Progression Over Time:
   Both systems lack adjustable frequency settings. This limitation may hinder progression for long-term users, as the body adapts to the same stimulation levels.

Why I Bought Visionbody Over Katalyst

I fit the profile of someone who knows how to exercise and prioritizes ease of travel. As a professional EMS trainer using Wiemspro suits for clients, I didn’t see a significant benefit to adding Katalyst, especially given its membership requirements. Visionbody offers the simplicity and portability I value.

I hope this comparison helps clarify the differences between WB-EMS systems for personal use. If you have any questions, feel free to email me at conradfitness@gmail.com or book a 15-minute call.
