What most trainees will notice when they begin bulking is they will put on a great amount of muscle mass in a short period of time, and then things suddenly seem to grind to a halt.
True, the more advanced and further along you get with your training, the harder it becomes to put on muscle mass because your body simply resists the change. But, there is often another reason which hardly anybody knows about… is
Muscle gains tend to slow within 4 weeks of bulking, because the central nervous system is overtaxed, and, the digestive system becomes less efficient at absorbing nutrients.
You simply need to give your body time to recuperate. It makes sense, and I cannot understand for the life of me why this is not common knowledge — so make sure you remember this tip and you will always be one step ahead of the game.
Anyway, like I was saying, when the central nervous system becomes overtaxed it resists adding muscle mass and starts to shut down. And, it goes without saying that if your digestive system becomes less efficient at sorting and the absorbing nutrients, your muscles will have less nutrients to build themselves up with.
My advice is this: Bulk for as long as you can until you notice your gains have slowed to a snail’s pace. At this point, you should start to train less strenuously for a few weeks to a month, to give your central nervous system time to recover, and also switch your diet from high protein to a more vegetarian-based diet along with getting plenty of water to cleanse your digestive system.
