# Front Lever vs. Back Lever: Scapular Mechanics, Carryover & Progression Order

> Although the Front Lever and Back Lever look like mirror-image horizontal holds, they recruit fundamentally different muscular and connective tissue structures. The Back Lever (OG Level 7) is a prone shoulder hyperextension hold driven by the anterior deltoids, pectoralis major, and distal biceps tendon, whereas the Full Front Lever (OG Level 10) is a supine shoulder extension hold driven by the latissimus dorsi, teres major, and anterior core.

## 1. Why the Back Lever Unlocks First (Level 7 vs. Level 10)
In the Back Lever, gravity pulls the torso downward while the hands are behind the back, placing the pectoralis major and anterior deltoids in a mechanically advantageous stretched position and allowing the ribcage and latissimus dorsi to create passive structural tension. Most athletes unlock a Full Back Lever 6 to 12 months before a Full Front Lever.
Furthermore, performing the Back Lever with a supinated (chin-up) grip directly conditions the distal biceps tendon for straight-arm pushing skills like the Planche and Iron Cross.
