I’ll be honest: I have never had a "butt". I have two kids, an office job, and a relationship with squats that consists of me doing 10 at home after a bad evening and then forgetting about it for three weeks.
A month ago I saw an ad for the Gymfit EMS Booty Trainer 2.0. My first thought: "classic Instagram scam." My second thought: "but 30-day returns..."
Here’s what happened over the next 21 days. I kept a diary every day. No filter, no sponsorship — I paid for mine myself.
The package arrived in two days. Inside was the trainer itself (soft silicone, feels skin-friendly right away), a USB cable, an elastic waist strap, and a manual.
The first thing that surprised me: no gel pads. I’ve tried TENS devices before and hated how quickly the gel pads dry out. This one has built-in silicone electrodes. One-time purchase, done.
I strapped it on, set the intensity to level 1 of 6, and pressed start. The first contractions felt like a pulsing kneading — like someone pressing a thumb rhythmically into your butt. Not uncomfortable. Just… unfamiliar.
After 20 minutes, the unit switched off by itself. I stood up. And I swear: I could feel my glutes for the first time in years. Not sore. Just… awake.
Three days in. 20 minutes on the couch at 21:30 while we were watching a crime series. My husband asked what was "buzzing" from my side of the couch. I showed him. He shrugged.
The weird part: My butt is sore. Like after a proper leg workout at the gym. But I haven’t done a single squat.
I do a little reading. EMS (Electrical Muscle Stimulation) has been used in physiotherapy and rehab since the 1970s. It sends electrical impulses directly to the muscle fibers. The difference from regular exercise: you activate deeper fibers that you usually miss.
This is the day I realized it works.
I pulled on my usual jeans — the ones I’ve had for about two years and which have always sat "a little flat in the back." They were tight over the butt.
Not uncomfortably tight. Just… filled them out in a way they hadn’t before. I took a photo in the full-length mirror. I compared it with a photo from day 1. The difference was subtle, but real.
I’ve started looking forward to the evening when I put it on. Not because I’m disciplined — but because it’s become part of the Netflix routine. You grab the remote, you grab the Booty Trainer.
Sunday lunch at my mom’s. My sister — who works out four times a week and has always been "the fit one" — looks at me and asks if I’ve started going to the gym.
I just laughed. "No. I’ve just put on a gadget while I watch TV."
This is the point where I realize it’s not in my head. I’ve gone up to level 4 on the device. The programs alternate between contraction and pulsing — when I choose "Lift," I feel the muscles working at a completely different angle than when I’m sitting at my desk.
I’ve also started taking the stairs instead of the elevator, which is extremely out of character.
Three weeks. 21 sessions. 420 minutes total use. These are the results:
What I didn’t expect: the change in how I feel about myself. Not "wow, I have the perfect butt now" — more like "I’ve actually had glutes all along, they just never got activated."
I’m continuing. Not 21 days in a row — but 4–5 times/week, in front of the TV. It’s so low-effort that it would be silly not to.

Yes. But not to everyone. This isn’t a miracle cure. It’s a tool that removes the most common reason butt training fails — that you don’t have time, don’t like the gym, or lose interest after two weeks. Put it into your Netflix routine and you’ve already won.
