Week 24

Slacklining at USC

Training session on Monday evenings 18.00 – 20.00 at Universum.
Temporary extra training on Thursday evenings!
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:

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.
