Tell me please which is the correct and natural way to say that someone wants someone to do things only after the person tells that person to do the things. Here is the context:
Do not do anything with the bar until I tell you to do something. Every move must be performed after my command/on command.
I am in doubt that my options are natural, but I cannot come up with something that is sounds native, so tell me please natural phrases to convey the meaning.
