    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!

    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

    • You need a reservation for every visit to USC.
    • Book a training in the timetable above.
    • 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)!
    • 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.

    Cancelling and no show fee

    Booked a class, but can’t make it? Please cancel in advance.

    • 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.
    • Your no show fee doesn’t end up on the big USC company pile. Check in which sports goal we’re investing the no show fee income.

    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.
