PEPPER Introduces the Muscle Activation Suit Built to Make Strength Training Smarter and More Accessible
Powered by electrical muscle stimulation (EMS) and decades of clinical science, the wireless suit and real-time guided app deliver a full-body strength session in 20 minutes
NEW YORK, June 9, 2026 /PRNewswire/ — PEPPER, a wearable fitness company, today announced its official U.S. launch with the introduction of its FDA-cleared Muscle Activation Suit, offering a more accessible, less intimidating, and more efficient approach to strength training. The suit uses electrical muscle stimulation (EMS) to enhance the body’s natural electrical signals, activating up to 90% of muscle fibers simultaneously — up to three times more than conventional training. The result is a low-impact, full-body workout that delivers the benefits of a 60-minute strength session in just 20 minutes, without heavy weights or added joint strain.
Strength training has always been important, but it’s now having a major cultural moment. Researchers and physicians increasingly point to muscle mass as one of the most important indicators of long-term health, spanning metabolic function, bone density, balance, and injury prevention. For the growing number of Americans using GLP-1 medications, maintaining muscle during weight loss has become a clinical priority.
“Traditional strength training remains out of reach for many, as it requires time, equipment, instruction, and a level of confidence that can feel intimidating,” said Emilia von Keyserlingk, founder of PEPPER. “When I first experienced EMS, the results were immediately obvious, but the overall experience was complicated. It relied on straps, cables, a timely process of manually wetting parts of the suit, and a trainer to guide every session. We built PEPPER to remove that complexity and make the experience simple and accessible, without compromising the effectiveness. You put on the suit. You press start. You become stronger.”
A Fully Integrated Training System
-
Wireless Smart-Suit: The dry, lightweight suit features 20 integrated electrodes that replicate the body’s natural muscle signals. No wires, cables, or complex setup.
-
The Powerbox: As the suit’s central command center, the compact, wireless control unit straps to the side of the suit and controls when and how each electrode fires. It also doubles as the battery with enough charge to last up to 10 workouts.
-
Real-Time Synchronization: The PEPPER app works with the suit’s control unit to sync each guided workout in real time — cueing every movement at the precise moment the impulse fires for maximum muscle activation.
-
100+ Guided Workouts: The app features an extensive library of workouts for all levels taught by certified coaches. No equipment needed.
-
Personalized Intelligence: The system’s AI captures performance and wearable data to recommend workouts tailored to each individual, adapting automatically as strength improves.
