Much more physical endurance and conditioning.
I'm not talking about skill, balance and coordination. Heck. Golf has more of those three chacteristics than gymnastics, but no one would say golf is more physically demanding over gym.
comparing golf to gymnastics is apples to oranges. Gymnastics and soccer are arguably the 2 most endurance sports that are out there. Basketball and tennis should be in the conversation as well, definitely ahead of football and baseball.
