thanks Nicky,

good distinction between American football and rugby athletes.
Rugby guys must be superfit. Stamina of soccer player and strength of a football defensive back. Super elite athlete to play on high level.

Speaking of super athletes.

Is crossfit big in NZ? I watch the finals every year and THOSE guys and women are FIT!!! Some of their workouts and movements are dangerous and go against how I was taught to work out (kipping movements are a joke to me) but can't deny that the top crossfit people are among the best athletes on earth.
