Why don't you post class principles in advance?

Because you'd cherry-pick. Everyone does.

Here's the honest reason: given the choice, most people skip the format they're worst at. Hate cardio? You'd never book BURN. Find the long holds brutal? SCULPT disappears from your calendar. And the thing you avoid is almost always the thing your body needs most.

The ONYX Method is a system, not a menu. FORTIFY, SCULPT, and BURN each build a different quality of strength, and the rotation is designed so they compound. Take two out of three and you don't get two-thirds of the results — you get a gap.

So we made the choice for you. Show up, trust the rotation, let the method work.
