Plenty of people, from athletes to those with busy lives or past injuries, would like the benefits of a two-hour workout in just 20 minutes without excess strain on their joints. That’s the promise of Katalyst’s four-piece bodysuit, the only FDA-approved consumer device to use full-body electrical muscle stimulation, or e-stim.

Sessions, he says, will leave you tired.
