At Fit by me you’ll become fit while having lots of joy. They offer classes from fitness jumping to Elliptigo (some sort of crosstrainer on wheels). In other words: here, you’ll be challenged, taken out of your comfort zone and you’ll re-experience the fun that working out can be. Watch out, because Fit by me is addictive.
And get access to 203 gyms and studios in Rotterdam with one sports membership.
