Summer is approaching – time to show off the abs you’ve worked for

Oslo-based personal trainer Ingrid explains why she prioritizes diet, hydration, sleep, and training first – and when she turns to an extra tool when her abs still lag behind.

Hi, I’m Ingrid and I’m a personal trainer in Oslo. I help my clients reduce body fat, build muscle mass, and get stronger without injuries. Every morning I stand in front of the large windows in the studio, watch the sunlight stream in, and feel grateful for the career I’ve built. At 33, I’ve helped hundreds of busy professionals become stronger, more confident, and injury-free.

Over the years, I’ve learned that real results always start with the basics. No matter how hard you train, you won’t reach your full potential without the right diet, enough hydration, and recovery. I tell all my clients to start with nutrient-dense foods that fuel the body, drink plenty of water throughout the day, and prioritize good sleep – because results are truly built during recovery.

Food, water, and sleep aren’t extras. They set the limit for everything else.

Once the foundation is in place, we move on to regular training. I see my clients give it their all in squats, deadlifts, and planks. But even so, many still struggle with one area: deep core activation and visible definition around the waist. No matter how dedicated they are, the lower abs and deep core strength often don’t keep up with the rest of their progress.

Regular training works the muscles from the outside. EMS activates them directly from within – deeper and more efficiently, leading to faster results.

That’s when I discovered GymFit Core Pulse Trainer.

I had tested several EMS devices before, and most of them had disappointed me. But after using the Core Pulse Trainer for three weeks, I was genuinely impressed.

Why it works: deeper core activation, better tone, and clearer definition when combined with real training.

I could feel muscles working that I normally only engage during advanced Pilates or heavy compound exercises. It activates the entire core, including the transversus abdominis, obliques, and rectus abdominis, as the perfect complement to regular training. It’s like getting an extra workout while you do your usual training or even when you walk along Aker Brygge.

Now I use the GymFit Core Pulse Trainer with almost all my clients in Oslo and even during my own training sessions.

The results speak for themselves. After just a few weeks, my clients notice better core stability, improved posture, and a tighter, more defined waist. One of my clients, a 41-year-old lawyer from Frogner, told me she could clearly see her abs for the first time in years – without doing extra ab exercises.

Now that summer is approaching, I’m more convinced than ever. When you have the basics in place – a good diet, enough hydration, sleep, and consistent training – the Core Pulse Trainer is a smart, time-efficient tool that helps your core catch up with all the work you’re already putting in.

You still need to train smart and eat well – but this device helps you get more out of every minute at the gym and delivers faster, visible results in the mirror.

Summer lifestyle confident body
The Norwegian summer calls to fjords and beaches. Feeling good in your body makes it easier to say yes to everything.

Whether you’re getting ready for beach days in Southern Norway, planning a trip to the fjords, or just want to feel stronger and more confident in your own body this summer – the GymFit Core Pulse Trainer may be exactly what your core has been missing.
