FOR MEN — SIZES S–2XL — FITS WAIST UP TO 125 CM (49 IN)
CHRIS CUOMO’S FAVORITESGYM IN A BOX®
CORE STRENGTH. 15 MINUTES. NO GYM REQUIRED.
The Men’s StimFitBelt™ is a microcurrent toning and sculpting belt built for men — cut, sized and fitted for a man’s body. Powered by patented ToneUp15® Pulse Body StimFit Technology, it wraps your waist and drives deep abdominal and core contractions in programmed 15-minute sessions. Worn directly on bare skin. 100% wireless. No gel pads, no cords, nothing to apply to your skin.
It does not replace your training — it completes it. COMBINE BOTH: add a session before or after your workout, or make it your core work on the days you can’t get to the gym.

NOT A REGULAR MEN'S WAIST TRAINER.
A HIGH-TECH CORE-ACTIVATION SYSTEM.
A regular waist trainer only squeezes. This belt works: targeted ToneUp15® Pulse Body StimFit Technology activation in fitted men’s sizing, for a secure, comfortable fit while your core trains.
Built for Men. Built Around Your Training.
How it works — in plain words: the belt’s dry electrodes sit invisibly against your bare skin — no sticky gel pads. Microcurrent pulses make your abs and obliques contract on their own, like doing hundreds of crunches while you work, drive or relax. You pick the program and the strength; the belt does the contracting.
Used by Chris Cuomo of NewsNation — and built for every man who trains seriously but doesn’t live at the gym.
What It Does for You
-
Targeted core activation — deep, repeated abdominal contractions that support core strength and a more defined midsection with consistent use.
-
A true training complement — wear it as a 15-minute session before or after your workout, or standalone on non-gym days. At your desk, on your commute, traveling — your core trains while you live your life.
-
Sauna-effect sweat and posture support — the structured corset-style fit traps warming heat around your waist to boost sweating during each session, and supports your midsection to encourage better posture while you wear it.
-
Adjustable intensity — multiple preset programs: the modes are preset pulse patterns, the levels are how strong each pulse feels. Start low, build up gradually to a strong, comfortable contraction.
-
Sized for men — men’s sizing S–XXL for a secure, fitted feel on a man’s frame.
-
Sizing (abdomen, around the belly button): S 60–69 cm (21–26 in) · M 70–79 cm (26.1–31.4 in) · L 80–95 cm (31.5–37.4 in) · XL 96–110 cm (37.8–43.3 in) · 2XL 111–125 cm (43.4–49.2 in)
-
For men.
-
100% wireless — no wires, no gel pads, USB rechargeable. Charge it, strap it on, press the button.
How to Use
-
Strap it on bare skin. Wrap the belt snugly around your waist, directly against your skin — never over clothing. The technology needs direct skin contact. (Clothing can go over the belt.) Charge the controller before first use.
-
Press the button. Power on the wireless controller, choose your program and intensity, and start low.
-
Live your life. The session runs 15 minutes and shuts off automatically. Work, commute, cook, relax — your core trains through all of it.

What to Expect
You will feel strong, real contractions from your very first session — that is the technology working. Visible results build with consistent daily use, alongside your training and nutrition: this belt supports the work, it doesn’t do it instead of you. A session is 15 minutes, up to two sessions a day. Individual results vary.
Questions, Answered
Can I use it with my training?
Yes — that’s exactly what it’s for. Combine both: use it as a separate 15-minute session before or after a workout, during suitable low-impact activity, or on its own on non-gym days.
What size do I need?
It comes in men’s sizes S–XXL. Choose your usual size — the belt should sit snug against your bare skin so the contact stays secure through the session.
