Wrist curl (light)
Supported wrist flexion/extension with light resistance
Goal
Targets wrist flexors with isolated lever arm for graded strengthening.
Motion taxonomy (reference)
Also called: palm up wrist flexion strengthening
Muscles — flexor carpi radialis, flexor carpi ulnaris, palmaris longus
Tendons — wrist flexor tendons
Bones / joints — carpal bones, radiocarpal joint, radius, ulna
Indexed benefits: improves load tolerance · strengthens wrist flexors · supports daily lifting tasks
Common contexts: forearm conditioning · return to lifting · wrist weakness
Best for
- Forearm conditioning
- Return to lifting tasks
Default dose
12 reps • 2 sets • 3×/day
Equipment
Light dumbbell or bottle
Avoid when
- Acute tendinopathy flare
- Recent fracture
Measurement targets
- Reps to mild fatigue
- Weight progression log
Setup
- Forearm on thigh or table with wrist past the edge; palm up for flexors.
- Hold a very light weight or water bottle.
Steps
Cues
- Forearm stays down.
- No gripping with the fingers only.
Common mistakes
- Using momentum from the shoulder.
Stop if you feel
Stop rules
- Sharp pain (≥ 4/10)
- Increasing swelling during or after
- New or worsening numbness or tingling
- Color change in fingers (pale, blue, red)
- Wound opens, drains, or feels hot
- Next morning is worse than the day before
Progressions
- Tiny weight increase when symptom-free.
Regressions
- No weight; range-only wrist curls.
What to do next — not a dead end
Suggestions use body region, goal, motion type, and allowed phases — not your medical record. After surgery or a flare, follow your clinician first.
Short sets — often 2×12 as a micro-session
12 reps · 2 sets · 3×/day
Light dumbbell or bottle
Phases 3, 4
Higher load or coordination — scale range and speed.
Next best movements
Later phase or richer progression when you are ready.
Prerequisite / gentler lane
Same region and intent — usually earlier phase or lower risk.
Commonly paired with
Different primary goal, same region — typical mixed sessions.
