Canonical coaching profile

Complete coaching guidance, with the evidence boundary visible

This profile is served from the canonical Airtable coaching library. Its theory tier and evidence confidence remain separate source-truth fields.

Theory

Theory tier S

Evidence confidence

Mechanics-led evidence confidence (D)

The tier is a reasoned biomechanics judgment. Evidence grade D is mechanics-led and is not direct hypertrophy proof; the full category evidence-control program remains pending.

Why it ranks: Dumbbell reverse curl is ranked for Forearm extensors because its named path directly expresses loaded wrist or finger extension; the multi-joint setup trades some local specificity for loading capacity. The main limitation is individual joint fit and execution consistency.
Primary limiter: Wrist position and brachioradialis strength, not just elbow-flexion capacity.
Safety and fit: Use a load that keeps wrists neutral and a pain-free elbow path; the grip change is meaningful only if position stays controlled.
What would change the call: Reverse or lower the placement if a corrected line-of-force model shows that another limiter owns the task, or if the declared range cannot be progressed repeatably.

How to do it

Setup

Stand tall with dumbbells at the thighs
Turn palms toward the floor
Keep wrists straight and elbows near the ribs
Brace the trunk

Execution

Curl by bending the elbows
Keep palms down throughout
Stop before the wrists fold
Lower slowly to full elbow extension

Common Errors

Letting the wrists extend
Swinging the torso
Drifting elbows forward
Rotating into a neutral-grip curl

Cues That Work

Knuckles forward; wrists like boards; elbows bend without traveling

No-Fly Zone

Avoid loads that bend the wrists back or require torso swing.

Programming

Sequence priority

Late

It is an accessory curl that can fatigue grip and wrist stability, so it follows heavier pulling and arm work.

Progression

Model — Double

Fallback model — Density

Keep palms down, wrists neutral, and elbows quiet; add reps before moving up one dumbbell step.

If it hurts

Pain is information, not a challenge to push through. Stop the set if pain is sharp, worsening, or changes how you move. These are exercise-selection options, not medical diagnosis or rehabilitation advice.

Work down this list in order. Stop at the first change that removes the pain.

Step 1
Setup tweaks
Reduce load, use alternating reps, or support the upper arms against a pad.
Step 2
ROM / tempo / bias
Use a three-second lower or a one-second midrange pause.
Step 3
Implement swap
Cable reverse curl or direct wrist extension.

Substitutions

Approved fallback

Cable reverse curl or direct wrist extension.

The Evidence

This changes elbow-flexor and wrist-stabilizer demands compared with a neutral or supinated curl. It is more than a cosmetic grip change, but it is not isolated wrist extension.
