A few times it has taken quite a while to get a machine repaired. On several occasions I have noted a cleanliness issue in the mens locker room . When staff/trainers are not working with a specific client and are in the gym area it may be an idea for them to offer casual advice on how clients are performing a specific exercise or proper adjustment on a machine.. That would be value added, and may even cause a gym user to try using a trainer.. Your staff are there,,. and if not with a paying client is a no cost service...
