Many usually talk about cycling for dieting, e.g. high calorie/carb days to prevent metabolism/energy crashes. But not many talk about breaks from bulking.
I have found through past bulks that I benefited from having lower calorie periods mixed in there (not too extreme). When I went back to high calories, there was a rebound effect and gains were better again.
I'm not talking about going backwards and forwards, rather, just eating around maintenance for a while so that when you over-eat again it works better.
