Berlin’s first cardio-focused workout that goes beyond indoor cycling and treadmills has arrived. Achter recently opened in Prenzlauer Berg, offering low-impact, full-body cardio sessions on a rowing machine.
Your first challenge might be finding the location of the studio: follow Google Maps until you spot a sign at the courtyard entrance, then walk through to the second courtyard where metal stairs lead up to the space. Change into your workout gear (most people arrive ready to go), and be sure to bring clean indoor training shoes. You can leave your stuff in the open lockers – the entrance door will be locked once the workout begins but make sure you bring your phone into the workout room. You’ll need it to connect your rowing machine to your personal Achter account.
When you enter the workout room, you’ll be given headphones that will provide both the music as well as your instructor’s guidance throughout class. Pick one of the twenty Concept2 rowers – if it’s your first time, the instructor will guide you through the setup. Adjust the footplate so the strap sits across the widest part of your foot. Each machine has a small display with a QR code to scan on your phone, where you can quickly create an account or log in as a guest. The screen tracks your performance and keeps you in sync with the class. At the end of the session, you’ll get a full workout summary in the Achter dashboard.
Every class begins with a rowing introduction. Your instructor will guide you through each movement, which you’ll also see demonstrated on the screen across the room. You’ll start by using just your arms, then add in the hip hinge, combine arms and hips, and finally bring in your legs to complete a full stroke. After that, you’ll step off the rower for some mobility work—think arm and shoulder stretches—before finishing with a few jumping jacks to get your heart rate up.
Then it’s time to get back on your rower for the cardio portion of class. If you’ve chosen a Pure Row class, the entire workout will be on the machine, while the Strong Row class mixes rowing intervals with resistance training off the rower for a hybrid strength-and-cardio experience. On the machine, the workout is effort-based, meaning you control the intensity. You can also adjust the damper to make each pull easier or harder. Sit tall, drive through your legs, and watch your display screen—your stroke will be mapped as a curve that you’ll aim to match with the ideal rowing form.
A pure row class might be set up in a pyramid structure, which could look like this:
Row at 60% of your maximum effort for 2 minutes, followed by about 35 seconds of active rest (either light rowing or a full pause).
Continue at 70% effort for 1:45 minutes, then rest for 45 seconds.
Intensity increases up to 90% as rowing time decreases and rest periods get longer.
Once you hit the peak, the pyramid reverses – working your way back down from 90% to 60%.
Then you’ll climb the pyramid once more
In a Strong Row class, you’ll alternate between rowing intervals at varying intensities and short bursts of strength training on the floor. Each rower is equipped with a selection of dumbbells for you to choose from. You could be doing goblet squats, shoulder presses or push ups, when off the rower.
The studio’s low lighting shifts from red during work phases to blue during active recovery, syncing with the music to create a fully immersive atmosphere while the A/C will keep you cool in summer.
Every class ends with a two-minute regatta, where participants race against each other. Your display shows power output (in watts) and stroke rate, so you can see how you rank alongside the rest of the group – an extra push to finish strong.
Finally, a few minutes of cooldown stretches help release the muscles you’ve worked. Once you’ve wiped down your rower and headphones, you’re done.
