Calisthenics ยท Biomechanics ยท Progression
Structured progression guides built on biomechanics โ not generic workouts. Understand exactly why you're stuck and how to break through.

Straight arm strength
Most people fail the front lever for the same two reasons: weak scapular retraction and poor posterior chain engagement. This guide identifies your exact weak point and gives you a clear, level-by-level path forward.
Straight arm strength
The planche is the skill that makes people quit โ because most programs skip the why. This guide dissects the exact mechanics behind the hold and the progression I built after months of research.
Best value
Both guides together. They share the same foundational mechanics โ training them in parallel accelerates both.
About
I'm k.zurb โ The Swiss Calisthenics Guy. I document my own calisthenics progression on Instagram, breaking down every movement through the lens of biomechanics to understand what's actually happening in the body.
No certification. No coach talk. Just someone who was stuck at the same points as you, went deep into the mechanics to understand why, and built a system that actually worked.
@k.zurb on Instagram โEvery guide follows the same four-step framework โ built to diagnose, not just prescribe.
Biomechanical analysis
Each guide starts by breaking down the movement โ which structures are involved, what position is required, and where the body naturally struggles.
Personal diagnosis
Simple tests you do at home to identify your exact weak link. You follow the progression that matches your specific block โ not a generic plan.
Structured progressions
Clear steps, in the right order, with precise criteria to move forward. You always know where you are and what comes next.
Radical honesty
My own plateaus, mistakes, and what actually worked โ included. Written by someone who had your exact problems.
