I make this post to support 
My favourite exercise in the nature is gymnastic and yoga.
I love to brith fresh air and to feel the mother Earth.
Usually I even don't use a yoga mat because for me grass or send is a natural carpet.
I combine stretching with deep breathing exersises and it gives perfect results. As more deep I breath as more I relax
Some times I like to do more active exercises - like flips, jumps or aerial gymnastic.
I want to add also that natural diet helps me a lot, I mean raw food - fruits and vegetables. It gives to body additional flexibility.
