Box It
Boxing training that works—even if you’ve never punched before.
What is Heat It Up Box It?
Box It is an intense group workout inspired by the world of boxing. You combine punching the heavy bag with dynamic cardio exercises in effective intervals, getting a full-body workout that improves your endurance, strength, and coordination all at once.
It’s not a boxing camp. It’s structured, accessible training with real physical results. No experience is necessary. Just show up and work hard.
The class moves at a fast pace from start to finish. The instructor sets the pace. You control the intensity.
What happens during the class?
A Box It session is structured around intervals that alternate between:
- Punching a punching bag — technique, power, and rhythm
- Cardio exercises — burpees, squat jumps, mountain climbers
- Active recovery — so you can push yourself again
You'll work your entire body. Your upper body, core, and legs are all engaged. The session lasts 45 minutes—no time wasted.
Who is Box It for?
Box It is perfect for you if:
- Want a challenging, structured cardio workout
- Are you bored on the treadmill or using exercise machines?
- Looking for a workout that provides both physical and mental relief
- I'm new to group workouts and want something that feels different
You don't need any boxing experience. The instructor will guide you through the technique.
What's in it for you?
If you practice Box It regularly, over time you will notice:
- A stronger upper body and core — punching demands more from you than you think
- Better fitness — interval training is one of the most effective methods
- Better coordination — rhythm and timing improve quickly
- More energy —not less, even if you feel tired afterward

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 :)
