I am huge into skiing and have been skiing for the past 20 years of my life. However, in high school, I unintentionally started wrestling after trying out for the basketball team and not making it.
Not only is this sport the toughest (mentally and physically), but it is the original olympic sport and the oldest sport known to man. The training, pressure, and just plain intensity that goes into this sport is unparalleled and I developed such a strong respect for it even after I let it go and didn't pursue it past high school.
Those who try and make fun of it because it's "gay" and theres spandex are just ignorant pussies who could never handle this sport. Wrestling is as gnarly as gnarly gets and it definitely helps you become a tough individual and provides you with disciplines that you keep throughout your entire life. Hell, I even use the wrestling mentality in skiing whenever I am nervous because I learned how to channel that insanely nerve-racking feeling when I was wrestling.There's something about going out in front of a gymnasium full of people and just going head to head with another guy and see who the better/stronger man is.
