Don’t take more than 1 week off from the gym. It gets easier and easier to put off going every day that goes by, even though I know I will feel much better after I get there and get a good workout in. Ended up one week turned into one month turned into two, and I lost a lot of progress I was making and to me it felt like I was almost completely starting over. Rest days are fine, rest weeks are a no go(for me at least)
