How to remind gym equipment to handle with care?
This depends on the guidance of the travel coach or staff, not the reminder. Some must be lifted lightly, which is a necessary strength control in training (some instruments are marked with "control") and should be taught. And those who do big load limit training, such as 1RM hard pulling, are not well controlled and rely on perfect facilities (good mats). As soon as you remind them, they will stop practicing, which is not good for them.
