Tighten Up
An hour dedicated to strengthening and toning your muscles.
What is Heat It Up Stram Op?
Stram Op is a targeted strength training program that systematically works the body’s muscles. You’ll focus on your arms, abs, glutes, thighs, and core through controlled exercises performed with precision and purpose.
This isn't a cardio session. It's dedicated strength training that builds a stronger body over time.
What happens during the class?
A "Stram Op" session is structured around:
- Isolation exercises — targeted work on specific muscle groups
- Compound exercises — exercises that target multiple muscle groups at the same time
- Controlled pace — slow, precise movements that engage deeper
You work methodically through the body. No time is wasted. Nothing is left to chance.
Who is Stram Op for?
Stram Op is perfect for you if:
- Want dedicated strength training in a group setting
- Want a firmer and stronger body over time
- Prefers controlled strength training over high-intensity cardio
- Want structure and guidance for your strength training
What's in it for you?
If you do Stram Op regularly, over time you will notice:
- Stronger and more toned muscles throughout the body
- Improved posture and stability
- A stronger core that supports all other movements
- A body that performs better —in training and in everyday life

I love the energy it gives me after a workout, and I can already feel the difference in my flexibility and core strength.

I was skeptical at first—Pilates and bungee didn’t sound like something for an old soccer player. But after just one trial class, I was sold. The workouts are intense, challenging, and fun all at the same time. Three of my friends have started now, too.

Definitely the best Reformers class in Copenhagen. A clean and inviting space, skilled instructors, and you can really feel the difference after just a few weeks.

As a new mom, it was hard to find the time and motivation to work out. Energii made it easy—flexible class times, booking through the app, and instructors who understand that you’re not always at 100%. I’ve regained my strength and found a new sense of community to boot.

I’ve been a member for over three years now, and the quality has only gotten better. New classes, new locations, and always with a focus on quality over quantity. My friends and I have made it our regular Thursday ritual—it’s equal parts socializing and intense workout.

Bungee Fly is addictive! It's the most fun workout I've ever tried.

Energii has completely transformed my daily life. I started out with a bad back and constant tension headaches. After just two months of working out three times a week, the pain is almost gone, and I sleep like a baby. The instructors remember your name and tailor the exercises to you—that makes all the difference.

I started three months ago and I'm already hooked. It's the perfect combination of strength and flexibility.

I’ve tried many different gyms, but Energii is in a league of its own. The equipment is always in perfect condition, the classes are varied, and the atmosphere is warm and welcoming. My body has never felt better than it does after six months of regular Reformer training here.

A top-notch experience! A wide selection of centers and classes, yet they still provide wonderful, personalized service when you contact them by email. And excellent service when it comes to changing your membership after a mistaken purchase—thanks, Energii :)
