Week 24

Slacklining at USC

Weekly training session at Universum in Amsterdam-Oost.
For both beginners and more advanced slackliners.
You’ll learn to balance and walk the slackline first, after which tricks will follow.
But it can get way more spectacular, like jumping or a butt and chest bounce!
Corona proof: mandatory reservations and additional house rules.

Which membership do you choose?

You can book a slacklining training with a single entry, multiple entry or a membership for one of the sports below:


Making a reservation and checking in

  • Make a reservation in the timetable above.
  • You need a reservation for every visit to USC.
  • You can make a reservation 6 days in advance.
  • You can have 2 active reservations for the upcoming 6 days. But as soon as your first reservation is over, you can make a new one. So, you can work out more than twice a week (if there are free spots)!
  • The number of reservations is unlimited on the day itself.
  • You can choose how you enter USC: by using the finger scan or by using the My USC – mobile access app. Download the app: Android and iOS.
  • If you choose to use the My USC – mobile access app, you check in by scanning the QR code at the access gates. This way (or by using your finger scan) you’re automatically checked in.
  • Are you training outdoor or in a space that can’t be reached by using the access gates? Check in by scanning the QR code at the USC location, or check in with your trainer/teacher.
  • Bring a towel and a filled water bottle.
  • Bring your own equipment as much as you can (like a mat, resistance bands and boxing gloves). Also for group classes and martial arts. The front desk offers a modest range of sports equipment and towels.
  • Read all reservation and house rules thoroughly before coming to USC! We can only keep things safe together.

Cancelling and no show fee

Booked a class, but can’t make it? Please cancel in advance: our capacity is limited!

  • Cancel up to one hour before the start of your reservation (but earlier is encouraged!).
  • Are you not cancelling (on time)? Then you risk a no show fee of €3,-.
  • Are you not paying the no show fee? In that case you can’t make a reservation/work out for 2 weeks.

Cancel your booking

Different slacklines

  • Beginner slacklines are shorter and close to the ground, so you can learn to balance and walk the line.
  • The rodeoline is a loose hanging line that looks like a swing. You can use it to relax, but you can also walk it.
  • A trick- or jumpline is a tight, 15 meter line. This line is used for jumps and dynamic movements.

USC teacher

The USC teacher for slacklining is Frank Hemmes. He is one of the instructors at Slacktivity.

Crossover with other sports

Slacklining adresses your ‘core stability’, and by doing so you’ll be using muscles you did not even know existed. Top athletes use the slackline to train their balance, knees and ankles. Slacklining is a very effective training for balance sports like (kite) surfing, gymnastics and climbing.
