— Method
Three rules.
I
Coached, not crowded
Class cap is 8. Every rep is observed. We learned this from years of watching people get hurt in big-box gyms.
II
Progressive, not random
You follow a 12-week block. We track your numbers, deload when you need it, and you get measurably stronger.
III
Barbells, not bullshit
No spin class, no booty bands, no shame circles. Just heavy compound work and the discipline to do it correctly.
