This is interesting, it reminds me of the (sort of) famous "tree hanging" exercise. Which goes like this. Go to a wooded area, find a tree with a strong branch above your head. Grab it and hang off it for a while. Do it daily for a brief time.

Supposedly this exercise helps in all sorts of problems that arise in a sedentary lifestyle (hands, arms, back etc).

Now, the only problem with doing it here is that most trees here are pines and strong branches start 20m above the ground...
