# Complete Planche Progression Guide: Biomechanics, Readiness Gates & Prilepin Tables

> Unlocking the Planche requires systematic progression through six biomechanical leverage stages—Planche Lean (L2), Frog Stand (L3), Tuck Planche (L5), Advanced Tuck Planche (L7), Straddle Planche (L11), and Full Planche (L15). Because locking the elbows at 180° places peak tensile load on the distal biceps tendon and anterior deltoid, athletes should program 45–60 seconds of total isometric volume per session at 65–75% of their maximum hold time.

## 1. The Physics of Straight-Arm Shoulder Flexion Torque
In a standard plank, the shoulders sit directly above the wrists, creating a near-zero moment arm at the glenohumeral joint. As an athlete leans forward into a Planche, the center of mass (located near the second sacral vertebra, S2) must remain vertically aligned over the base of the hands. Consequently, as the legs extend from Tuck to Straddle to Full Planche, the shoulders must shift progressively further forward ahead of the wrists.
At full horizontal extension, the anterior deltoid, clavicular head of the pectoralis major, and biceps brachii long head must generate torque equal to Bodyweight × Moment Arm, while the serratus anterior prevents the ribcage from sinking between the scapulae.

## 2. Overcoming Gravity Isometric Prilepin Programming
Testing a 1-rep max isometric hold to failure every workout causes central nervous system fatigue and biceps tendonitis. Instead, test your max clean hold once every 4 weeks, take 70% of that duration as your working set duration, and perform 4 to 6 sets with 3 minutes of rest (monitored via the ENIX Live Activity Hold & Rest HUD).
