The Problem

I developed Plateau Buster Protocols around a simple question:

“My XYZ muscle group is not growing. What should I do?”

When you train long enough, you learn that not all muscles respond the same way to training. Anyone who has dedicated themselves to building their physique knows this firsthand. You have muscle groups that grow easily and muscle groups that lag behind. You have muscles you can feel working from the first rep and muscles you struggle to form any mind-muscle connection with.

This is normal. Unless you are blessed with Olympia-level genetics, everyone has their stronger and weaker muscle groups. The common ones are calves and forearms. But it could also be the glutes, lats, or shoulders.

The point is that everyone has that one muscle group that is slow to grow, underdeveloped, and lags behind all your other muscles.

So what do you do about this?

The Confusion

You’ll be given different strategies depending on who you are talking to:

“Bomb the muscle with insane volume.”

“Revise your exercise selection and choose only the most effective movements.”

“Focus on neuromuscular innervation and increase the mind-muscle connection.”

“Get ‘weird’ with your exercises and experiment.”

“Train the muscle every day or every workout.”

“Stop focusing on the muscle, and give it a break.”

Seems contradictory, right? You are being told to use high volume by one person and then to NOT train a muscle by someone else.

Here is the thing: none of these are wrong. But none of them are the full picture, either.

If you read the training literature and exercise science, these strategies stop contradicting each other and start fitting together. The issue is not that one strategy is right and the others are wrong. The issue is knowing when and how to apply each one.
