Both physiques take work.
One is what happens when everything is dialed in—training, nutrition, recovery, timing, and a lifestyle built around the goal.
The other is what happens when those same habits become sustainable.
Most people look at both and think they're impossible.
They're not.
The difference isn't genetics. It isn't secret supplements. It isn't motivation.
It's understanding when to push, when to maintain, and how to build a plan you can actually live with.
Getting lean is a skill. Staying lean is a different one.
That's where coaching matters.

Chase progress and consistency, not perfection. Perfection doesn't exist.

IG - you make everything harder with your glitchy app.

One day it works, next you can't even size an image.
