Answering this question is straight forward, but finding that type of environment is difficult.
-There will always be a higher level training group so at some point, a coach has to say no, they can’t move you up.
-Does the player show a disciplined effort to train at 100% no matter who they're with?
-Is it fair for the higher level players when the lower level player joins them?
These are the things I discuss in this podcast, along with how important it actually is to train with higher level players.
