They say even though it's a simple idea, mastering the 'sport' requires plenty of time and discipline. Danny Lerwick says, "You find out that it takes a lot of time, energy and patience. You have to completely re-learn a whole new thing. It's like having to learn how to ride a bike or ski. You have to train your brain to do something completely new that it's never done." Lerwick says the sport of slack-lining has plenty of health benefits, from improving balance and coordination, to strengthening your core.
