In this awesome role, you’ll be the fitness hero who guides our members through their workouts with a big smile and makes sure everything stays tidy, clean, and safe. You’ll lead energetic group classes like Circuit Training, Booty, Sixpack, Functional Training, and Hyrox—and if you can teach boxing classes too, that’s a huge plus!

In addition, you take new members by the arm and give them a tour of our gym so they feel right at home. You motivate our members to get the most out of their workout and make sure the gym is always buzzing with energy! Behind the counter you take care of registrations, answer members' questions and welcome everyone with a big smile. No day is the same!

We don’t think a degree is the most important thing. Motivation, enthusiasm, and a desire to learn matter much more to us! You’ve gained practical experience, aren’t afraid to lead a group, and get a boost from guiding others. At GymOne, there are plenty of opportunities for growth, and hard work is rewarded. Plus, you’ll be working in a team with the nicest colleagues, where you’ll feel respected and valued and learn from each other every single day!

Are you the kind of person who can’t wait to push people through their final set? And do you consider the gym your second home? Then send us your resume and cover letter right away—and who knows, you might soon be on the gym floor at our new location in Haarlem!
