Author Returns $3,000 Katalyst EMS Suit After 1 Month as Numbness Derailed Workouts

Summary
One month of use led the reviewer to return Katalyst’s $3,000 electro-muscle-stimulation suit after repeated pins and needles, numb limbs, coldness, and workouts that felt more disruptive than efficient.
20-minute sessions are Katalyst’s main pitch—the company says they can match a 2-hour strength workout—but the suit requires soaking electrode pads, delivers intense electrical pulses during basic movements, and left the author unable to row or swim comfortably afterward.
Brendan Kennedy, Katalyst’s CEO, called days-long tingling “extremely abnormal” and advised using more water and adjusting settings; disabling the arm stimulation eased hand symptoms but did not make the system workable or enjoyable.
Research and user testimonials suggest EMS can help with time-efficient, low-impact training, especially for beginners or people with limited mobility, but experts cited in the report said it is not a shortcut or replacement for conventional strength training.
The experience also underscored wider concerns around the EMS market: intensity ratings are not standardized across brands, Katalyst is FDA-cleared rather than approved, and the company only recently stabilized supply after earlier delivery problems.
