Hey I was wondering about rest days while using an extender since I have heard different things. For the past two weeks I have not taken a rest day since I read multiple things that said rest days aren't necessary and that you want to wear the extender for pretty much as long as possible. Is this true? I don't really see how that can be, yet when doing manual exercises most people say you definitely need some rest. If this is true, could anybody explain why rest days aren't necessary when using an extender? Thanks guys
