After two pregnancies, she didn’t recognize her own stomach and her back was in constant pain. Sara Bergström found something that actually worked — without needing a single extra minute.
When my youngest son was seven months old, I stood in front of the mirror and felt unfamiliar in my own body. The stomach that never quite went back. That empty feeling in the middle — as if something had disappeared somewhere during the two pregnancies. The back that ached constantly from breastfeeding, carrying, and lack of sleep.
I didn’t want to go back to any particular look. I wanted to feel strong again. To feel that my body was mine.
The problem was time. With two small children, a part-time job, and a partner who also works full-time, there aren’t any spare hours to spend at the gym. Every time I tried to schedule a workout, something happened — a sick child, overtime, sleep deprivation that made the idea of burpees completely absurd.
It was a colleague at work who had tried it. I was skeptical in the way you always are about things that sound too easy. But she described it in a way that stuck with me: that it didn’t demand anything from you. That it only worked while you were living your normal life.
EMS — electrical muscle stimulation — is a technique that sends small electrical impulses directly to the muscles and makes them activate just like during regular exercise. The technique has long been used in healthcare, including rehabilitation after childbirth and for back problems.
It demands nothing from me. It happens while I’m living my normal life.
Core Pulse Trainer from Gymfit was the belt I found. CE-certified. Discreet enough to wear under clothes. Seven hours of battery life and forty minutes of charging.
I started at the lowest level. A pulsating feeling in my stomach that felt strange the first few days, then more and more natural. I wear it when I walk to preschool, when I go shopping, when I sit at the computer.
It demands nothing from me. That’s the part I didn’t understand until I tried it myself: that you can actually activate your abdominal muscles without spending a minute on it.
After two weeks I noticed I was sitting more upright. Not because I was thinking about it — but because my body was starting to find its way back to a more natural position. The back pain that had followed me since my first pregnancy eased noticeably.
Try Core Pulse Trainer risk-free →My stomach feels firmer. Not dramatically — I don’t expect a six-pack — but noticeably. The support around my waist is back in a way I haven’t felt since before my pregnancies. I stand straighter. I have more energy during the day.
The most important thing for me isn’t how it looks. It’s how it feels. Feeling that my body is strong again, that it carries me, that I don’t have to choose between being a mother and taking care of myself.
