In Korea, there are outdoor "gyms" everywhere; at the playground, along hiking paths or along the rivers. Once when we were hiking in the mountain behind our home we came upon this gym. I was so impressed with the man hanging upside down (he's wearing the green coat and black pants).
I haven't tried this, yet.
Congratulations to Beth Hunt. She knew where every picture was taken in my last post, "May is Just Flying By". Way to go, Beth. You are a winner.
