The most brutal sweat i've experienced is one that used to take place every morning at DFHQ,i don't know how many of you have ever been to DFHQ in Chaguaramas,that's opposite Chagville,it have a Gym there and was the home of DF Football.
Every morning players and non players included used to play in there before going to their place of duty,the teams were called skins and shirts,you choose which team you wanted to be on,numbers did not matter,just make sure you could handle yourself,yes it had a couple broken legs but say what it was a fun thing for everybody,i always tried to choose the team that had the bruzers on it in order to survive.
