There is nothing magic about it - you either break down the muscles or you don’t.
There is no need to “guess” - at the end of the workout, your muscles should be completely exhausted and fully pumped. If they are, this means that hypertrophy will occur.
It is as simple as isolating the muscle and exhausting it. That is ALL it takes. Absolutely everything beyond that is superfluous.
You people act like there are some complicated factors involved which you have no control over. Bullshit. You have control over absolutely everything. I used to think the way that you do before I understood what the hell I was doing.
I used to think that if I did a heavy compound lift, my muscles would grow as a result of some undetermined, “special” quality of that lift. Call it HGH or whatnot, it’s simply mystical bullshit. You might as well dance around a pole and ask some raven deity for bigger muscles.
For your muscles to grow, you need to put stress on them DIRECTLY and then exhaust the hell out of them. There is no better method for accomplishing this than isolation machine training.
I’ll say it one more time:
Hypertrophy MUST occur if the muscle is isolated and taken to exhaustion.
It is a law of physiology. It is not open to debate. It is not a grey area. There are no “maybe’s” involved.
Do not tell me that you did a set of curls with perfect form, taken to complete exhaustion, and your arm did not grow at all. That is a lie. Your arm will grow immediately from the pump, and then it will retain a portion of that fluid for hours and days after the lifting session. Bodybuilders see this ALL the time. I have been doing it every day for the past year. It is a process which you can directly trigger, directly influence, and directly witness. There is absolutely no guesswork or assumption to it at all. You see it happening with your own eyes and it is directly within your power to modify it as you wish.
This is what bodybuilding is all about. If you haven’t “broken through”, you’ll never get it.
