Another cool feature would be so that a maximum of 10 other players can /join and see the boxing match. (maybe)
You can also select the number of rounds, a maximum of 3.
The command can be: /1v1fist
Then a menu will show up to choose one of the gyms.
Inside the gyms where there's a boxing ring, you and the opponent will not be able to leave the ring until the rounds are done (add an invisible wall or something).

This will make players to frequently visit the gym and get in shape for both fights outside and inside the ring!
