The idiom "on and off" means to do something or have something happen intermittently or sporadically. It implies that the action or occurrence is not consistent or continuous, but rather happens in a stop-start fashion. For example, if someone says they have been exercising on and off, it means they have been exercising irregularly, with periods of activity followed by periods of inactivity.
