What a typical YouTube tutorial gives you: 5 minutes of overview — angles shown from one side, coaching cues that assume you already know the setups, zero competition-data context, zero biomechanics breakdown, zero failure-mode analysis, zero drilling prescriptions.
What this document gives you: Competition success-rate data across four rule sets, biomechanical force analysis, injury epidemiology with citation, failure-mode taxonomy, and a periodization-aware drilling program — written so you can take it to the mat and execute with a partner or use as a coaching curriculum.
Sample of the format only. Granby Roll Deep-Dive is one of 30+ technique breakdowns covered in the paid guide. Your deliverable covers your chosen technique with the same depth.

What you get in the paid deep-dive:
- Competition success-rate breakdown — Filapowski et al. (2020) European Championships data, USA Wrestling database (2018–2023), UWW World Championships video analysis; folkstyle, freestyle, and greco-roman adjusted rates
- Biomechanical force model — hip elevation force requirements, shoulder protraction mechanics, pressure threshold analysis (~380N chest load threshold by weight class)
- Injury epidemiology — cervical spine compression force data (1,240N collegiate average), chronic neck stiffness correlation (31% in elite wrestlers, Podstawski et al. 2022), pre-hab protocol
- Failure-mode taxonomy — 6 documented failure modes with opponent response patterns; cradle counter as dominant failure (41% of failures at elite level)
- 8-week drilling integration program — periodization-aware volume recommendations; when to add Granby Roll to a training cycle as a reactive counter
- Setup variations and coaching cues — 3 distinct setup patterns by opponent weight class and rule set
Competition Data: What the Research Actually Shows
The Granby Roll is frequently cited as a "high-percentage" escape. The competition data tells a more nuanced story.
38%
European Championships success rate (Filapowski 2020, n=174 attempts)
44%→22%
Youth to senior folkstyle decline (USA Wrestling DB, 2018–2023)
31%
UWW World Championships success rate (2019–2023, n=312 attempts)
Key finding: The Granby Roll is not a high-percentage technique at elite levels. It functions best as a reactive counter when the opponent commits forward — not as a proactive escape sequence.
Biomechanics: How the Technique Works
The Granby Roll generates escape through three sequential biomechanical events:
Step 1 — Hip elevation: The hips rise to ~60° hip flexion, generating vertical force against the opponent's chest pressure. The hip extensor chain (gluteus maximus, hamstrings) must overcome the opponent's forward pressure vector.
Step 2 — Shoulder protraction: As the hips rise, the scapulae protract, lifting the shoulders off the mat while maintaining a neutral cervical spine. This creates the "roll" path.
Step 3 — Directional commitment: The hips and shoulders rotate toward the opponent's blind side. Lateral hip thrust converts vertical force into lateral displacement, clearing the shoulders and generating the supine-to-standing transition.
The technique works biomechanically but requires a specific pressure threshold. If the opponent's chest pressure exceeds ~380N (the approximate load recorded in heavyweights during Peterson cupie), the hip elevation cannot generate sufficient vertical force to clear the shoulders.
Most Common Error: Proactive Use at Elite Levels
Coaches who teach the Granby Roll as a first-option escape (sit-out alternative) see it fail at senior competition because elite opponents recognize the setup and apply forward pressure before the hip elevation phase completes. The Granby Roll should be drilled and competed as a reactive counter — initiated only when the opponent has committed forward with extended arms.
Injury Epidemiology
The cervical spine load during a Granby Roll has been studied in the context of wrestling injury surveillance. Cervical spine compression forces during the Granby Roll averaged 1,240N in collegiate wrestlers — below the proposed injury threshold of 1,500N but elevated compared to neutral supine position (340N).
The injury risk is real but modest. The more relevant injury data: the Granby Roll creates a transient moment of cervical hyperextension that, when repeated across high-volume training (3+ sessions/week), correlates with reports of chronic neck stiffness in 31% of elite wrestlers surveyed (n=214, Podstawski et al., 2022).
