If they’re adventurous and athletic, this video will definitely get your attention as a fun activity for your kids, be they middle school age or teens. Looks like a lot of fun! Of course, what you see here is at the ‘expert’ level- you can see the learner’s edition on the Gibbon website.
Needless to say, this is an inherently dangerous activity that needs to be treated with respect, but so are plenty of other things your kids do like snowboarding, heading a soccer ball, etc.
This is a great core exercise (balance) and the time your kids spend mastering this will be like sending them to the gym to workout. That helps with the price tag on the equipment to set up your slack line. Believe it or not, you don’t HAVE to have trees to work with for this- although that’s certainly the easiest. Trees do need to be mature and 24″ in diameter.
My bet is you’ll have lots of kids over at your house trying this out and trying to master the technique. And that’s way better than a lot of other things they could be doing.
