My daughter's gym made all the changes required by the various, ever changing health laws but only two stuck. Parents couldn't enter the gym because of the numbers cap, and they really haven't been allowed back in since (although as it is a warehouse they can watch from the roller door still).
And there is now somebody on the gym door taking attendance as gymnasts walk in. This used to be done by the coaches and was fairly informal.
The other thing is a vibe rather than an action, but two long shutdowns means people know from experience that as long as you stay strong and flexible, time off gym is not the dealbreaker that it used to be treated as. That long family holiday - not a problem, not even a little bit. Need a full term off for exams - take it. Might take you a month or so to ease back in when you return, but you CAN return.
