I realise that you need a license to train a pro but do you need one to run a gym ? might seem a stupid question but am curious
If you're running an amateur gym (with intentions of the boxers to compete) then they would have to be afilliated to the W.A.B.A, and you need to do all the necessary CRB checks, insurance, etc. For a pro gym, I don't think you need an actual license to run the gym itself, only a license to train the fighters/work their corners etc.
