I started doing Yoga last year because I had a sciatica issue flare up. It has helped tremendously. There are muscles I never knew I had that I stretch in Yoga.
Forget the leotards. Yoga is Hard! I guarantee you will be shaking and struggling to support your body in some of those poses when you thought you were a strong guy (I sure did and still do struggle, its freaking tough!).
It has improved my balance, range of motion, and strengthened muscles… All of which helps when stalking game.
