# Front Lever Readiness & Torque Calculator

> The ENIX Front Lever Readiness Calculator maps your strict Pull-Up capacity, Weighted Pull-Up 1RM (% Bodyweight), and Hollow Body / Tuck Front Lever isometric hold duration into a 0–100% Front Lever Readiness Score. Because the latissimus dorsi and teres major generate the primary shoulder extension moment, a +55% BW Weighted Pull-Up predicts Straddle Front Lever readiness and +70% BW predicts Full Front Lever.

- Formula: Shoulder extension torque in the Front Lever scales directly with Total System Pulling Load ((Bodyweight + Added Weight) / Bodyweight), modulated by lower trapezius scapular depression and rectus abdominis anti-extension stiffness.

## Benchmark Tiers
| Tier | Benchmark | OG Level Equivalent | Unlocked Skill Node | Notes |
| :--- | :--- | :--- | :--- | :--- |
| Beginner | 10–12 Strict Pull-Ups · +15% BW Pull | OG Levels 3–4 | Tuck Front Lever | Ready to begin straight-arm scapular depression hangs and 10–15s Tuck Front Lever sets. |
| Intermediate | +35–45% BW Pull · 15s Tuck FL | OG Levels 5–6 | Advanced Tuck Front Lever | Extend hips to 90° with a flat lumbar spine while maintaining straight-arm depression. |
| Advanced | +55–65% BW Pull · 12s Adv. Tuck FL | OG Levels 7–8 | Straddle Front Lever | Strong latissimus dorsi torque ready for full hip extension in a wide straddle split. |
| Elite | +70–85% BW Pull · 10s Straddle FL | OG Levels 9–10 | Full Front Lever | Elite horizontal pulling leverage capable of 6–10s Full Front Lever holds and Front Lever Pull-Ups. |

## FAQs
### Does bodyweight height affect Front Lever difficulty?
Yes. Because torque equals Force × Moment Arm (τ = m·g·L), taller athletes with longer femurs experience a longer lever arm at the shoulder joint, typically requiring an extra +5% to +10% Weighted Pull-Up relative strength for the same hold duration.
