What is (in your opinion) the hardest sport in the u.s.a?

You better belive gymnastics is fucking hard. Soccer may take more long term endurance and thats the only reason I pay attention to it that and my roommate loves it but gymnastics isn't about tossing a ball thru a hoop or hitting a ball with a stick its about complete and total mastery over every aspect of your body. Kids don't start learning other sports when there 3 years old and practice every day for 10 or more years to get good at it. Growing up I had gymnastics or dance or both every single day. Even when I didn't have classes scheduled I'd get dropped off at the gym to practice. Yea its hard and super competitive you can't rely on team mates to carry you its do or die trying.

Boxing.

marriage

Archery.

Cross country and marathons nobody will run as much as them.

I play soccer and it's pretty easy. You just have to run a lot.

bowlin aint no sport

Cricket

robocup. have you ever taught a robot how to walk? It is not easy let me tell you.

Well bowling is for kids and grandpas, except for football the others are for homos. so you didn't give much choice

I would think luge or bobsled would be the most difficult sport. The equipment is VERY fast but very difficult to control.
