Towel bunching
Finger flexion pull-in (towel inching)
Goal
Builds composite flexion endurance with low joint compression.
Motion taxonomy (reference)
Also called: finger squeeze into towel
Muscles — finger flexors, interossei, lumbricals
Tendons — flexor tendons
Bones / joints — DIP joints, MCP joints, metacarpals, PIP joints
Indexed benefits: builds grip endurance · improves finger flexor strength · trains intrinsic control
Common contexts: arthritis exercise · dexterity-strength blend · grip strengthening
Best for
- Intrinsic recruitment
- Grip endurance without heavy load
Default dose
8 reps • 2×/day
Equipment
Hand towel
Avoid when
- Acute flexor tendon repair windows
Measurement targets
- Inches gathered per rep
Setup
- Lay a towel flat on a table; anchor one edge with the forearm.
Steps
- 1Scrunch the towel toward you using fingertips and palm.
- 2Straighten the towel and repeat.
Cues
- Use the whole hand, not just the thumb.

- Sharp pain (≥ 4/10)
- Increasing swelling during or after
- New or worsening numbness or tingling

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.
