Definition
Strict Curl is an isolated biceps movement performed against a vertical support. The goal is to lift the maximum weight while the body stays completely still.
Strict Curl
A single-joint strength discipline judged purely on the curl itself — no swing, no leg drive, no shortcuts. One clean rep decides the winner.

One Rulebook.
One Standard.
One Winner.
The Pro Tour runs across a full season: athletes travel between ranking events, banking points and building toward Pro Card status. The season concludes with the World Strict Curl Championship, where the year's leaders settle the title.
Strict Curl isolates the biceps against a vertical support. The athlete curls as much weight as possible while keeping the rest of the body still — no swinging, no leg push, no back lean.

WSM Standard
General Rules of the Discipline
One rulebook governs every World Strongman Strict Curl event — identical judging, identical records, anywhere in the world.
Integrity of Execution
Unlike a regular curl, any use of momentum, leg drive or back engagement is strictly forbidden. This is the gold standard of arm strength.
Governance
All World Strongman Strict Curl competitions run under a single regulation, ensuring uniform judging and record keeping worldwide.
Technical Execution
-
01
Contact Points
The athlete must keep constant contact with the vertical support: upper back (shoulder blades) and glutes pressed to the wall throughout the lift.
-
02
Foot Placement
Heels must be no more than 12 inches (30 cm) from the support. Any movement or sliding of the feet during the lift disqualifies the attempt.
-
03
The Commands
Athletes must wait for the “CURL” command to start. After locking the bar at the top (chin/throat level), wait for the “DOWN” command to lower the weight.
-
04
Continuous Flow
The lift must be one continuous movement. Any pause, double bounce or downward travel after the start results in a “No Lift”.
Note: elbow/bench sleeves and bench shirts are banned under WSM standards. Only standard wrist wraps and a belt are allowed.
“No Lift” Criteria
- Loss of contact —any visible gap between shoulders or glutes and the support during the lift.
- Foot movement —a step, slide, or heel/toe lifting off the platform; feet must stay motionless.
- Downward movement —any lowering of the bar after the upward lift has started; the movement must be continuous.
- Command violation —starting before the “CURL” command or lowering the bar before the “DOWN” command.
- Knee drive —bending or snapping the knees to create momentum; legs must stay straight and stable.
- Uneven extension —incomplete elbow lockout at the start or an uneven bar path (one end noticeably higher).

Questions & Answers
FAQ
Yes — chalk is fine for improving grip on the bar.
An EZ-bar is standard, which is easier on the wrists, though a straight bar sometimes appears at Pro League stops.
A plain cotton t-shirt is fine, as long as it doesn't add any mechanical support to the lift.
Contact loss (shoulders, glutes leaving the support), foot movement, downward motion of the bar, command violations, knee drive, or uneven extension.
Elbow sleeves, supportive shirts (bench shirts, erector shirts), and lifting straps or hooks are not permitted.
Consistent top finishes at Pro Tour ranking events across the season earn a Pro Card and access to Pro League stops.
