That one you ski, shoot and race at the same time
When you go to a warzone and try to survive.
There is no difference between eSports and sports, why you share kinds of sports? Stop doing it, please
From traditional sports and not going to stuff you only see on the olympics, probably rugby.
There shouldn't be other sport where so much people quit just after their first day.
I guess MMA since the really high amount of injuries..
But I would say every sport is the hardest as long as you push yourself.
1 - American football
2 - MMA
3 - Hockey (I never played hockey, but I think is hard af)
4 - Calisthenics (U must have so many patience, and this for me is hard)
5 - Powerlifting
I also think snowboard is hard, but same shit as hockey i never did it, so idk :(
tried both water polo and football and water polo almost rekt my lungs and my arms.
