Take a week off and try adding an extra rest day or two into your schedule.
"in the howling bleeding nights, the dogs plunge into the Volga and swim desperately to gain the other bank. The nights of Stalingrad are a terror for them. Animals flee this hell; the hardest stones cannot bear it for long; only men endure."
My breaks come when i get sick. If im coughing like a madman, then i wont go. Until that cough, stops i dont workout. I get sick about once, maybe twice a year. Probably two, 1 week breaks per year for me.
