Fitballing! (Honestly there really isn't a true name for this, but it's what most people in the parkour/freerunning community call it.) Basically, you head on over to the beach, dig a big-ass hole in the sand, blow up your fitness ball, and bury it about three-quarters of the way in sand. Then you do flips 'n shit off of it! :D
I haven't personally had a chance to do this yet. But I'm headed to my favorite beach spot this coming weekend and I definitely plan on trying it out! I also definitely plan on filming everything I do, so expect some sort of lame edit in about a week :)
For now, I'm sure you want to see what I'm talking about, so check out this video!
I'll let you know my final thoughts on this activity after I have had a chance to experience it myself c:
