I visited a spa not too long ago while I was traveling that had bamboo staulks and hemp type rope for a bowflex, similar type of equipment,. The place was all natural colors, light greens, plans and all that... it was a meditative type of work out area, water sounds, and the ting tang tong toe music stuff.... totally awesome!!!!!!!!! EXPENSIVE!!!!
If you are talking about a "freerunning" type of facility, I could go on and on. as far as trees to climb and jump from, and pullup, up hills, down hills, high grass for friction type running, beams for balancing running, and pegs to jump from one to the other....
I am an athlete that loves this sort of stuff....
nothing better than running, and swimming accrossed a river to climb a tree so I can jump back down into the water to swim back accrossed to climb a tree to do pullups, to drop into the water....
okokok,,, I'll stop now.
but I hope I have helped you some.
