Eccentric Hammer Curl For De Quervain’s

A slow-lowering hammer curl biased toward the thumb side to build tendon tolerance for De Quervain’s–type wrist/thumb pain (texting/mommy thumb).

Muscles Targeted

Thumb-side tendons involved in De Quervain’s (EPL/EPB area), forearm muscles, and grip control.

Key Benefits

  • Builds tendon tolerance using controlled eccentric loading
  • Easy setup with forearm support to reduce compensation
  • Simple progression with light weights
  • Great option for “texting/mommy thumb” rehab plans
The lowering phase is the focus—keep it slow and smooth.

Equipment Needed

Table/bench for forearm support. Optional: 1–5 lb dumbbell or light weight.

How to Perform Eccentric Hammer Curl For De Quervain’s

  1. Support your forearm on a table with the wrist/hand free.
  2. Use a neutral (hammer) grip.
  3. Assist the “up” portion if needed.
  4. Lower slowly (3–6 seconds) under control.
  5. Repeat for reps, then rest.

Programming Options

  • 2–4 sets of 8–15 reps
  • Lowering tempo: 3–6 seconds
  • Perform 3–6 days/week depending on tolerance

Why This Variation Works

Eccentrics load tendon tissue in a controlled way, helping rebuild capacity for gripping, lifting, and repetitive thumb/wrist use.

When to Use It

De Quervain’s rehab programs, flare management phases, or as a tendon-loading strength builder once symptoms allow.

Frequently Asked Questions

Should this hurt?

Mild discomfort can be normal, but sharp pain means reduce load, shorten range, or stop.

How heavy should I go?

Start very light—only increase if you can control a slow lowering every rep.

How slow should the lowering be?

Aim for 3–6 seconds. Slower is fine if you can keep it smooth.
