Key pinch.
Tip pinch.
Two different jobs.

The pinches trained separately, plus the small muscles that shape the hand around a handle.

Pinch differs from grip

Key pinch, tip pinch and three-point pinch are separate abilities. They fail separately and are trained separately.

Intrinsics versus extrinsics

The long muscles in the forearm move the fingers; the small ones inside the hand shape and stabilise them. The small ones are almost never trained.

Lumbricals hold the shape

The lumbricals straighten the fingers while the knuckles stay bent — the position used in almost every grip on a handle.

Three couplets · two rounds · twelve minutes · hands that hold on

A

Thumb joints

Thumb IP flexion + key pinch hold
A1

Thumb tip flexion

60 s · slow reps

Hold the base of the thumb still; bend only the last thumb joint and straighten it.

Easier assist with the other hand  ·  Harder hold two seconds

R1R2—
A2

Key pinch hold

5 × 10 s · ×2

Pinch a coin or card between the thumb pad and the side of the index finger; hold.

Easier gentler pinch  ·  Harder thicker object

R1R2
B

Spread

Banded spread + paper hold
B1

Banded finger spread

60 s · slow reps

Band round all four fingers; spread them apart against it and close slowly.

Easier no band  ·  Harder thicker band

R1R2—
B2

Paper hold

12 × 8 s · ×2

Hold a sheet of paper between each pair of fingers in turn while it is gently pulled.

Easier one pair only  ·  Harder thinner paper

R1R2
C

Shape

Lumbrical reps + intrinsic plus hold
C1

Lumbrical reps

60 s · slow reps

Knuckles bent, fingers straight; bend and straighten the knuckles only, tips staying long.

Easier smaller range  ·  Harder hold two seconds

R1R2—
C2

Intrinsic-plus hold

12 × 8 s · ×2

Knuckles bent, fingers straight — the tabletop shape — held against light resistance.

Easier no resistance  ·  Harder hold longer

How to run it

  1. The thumb is forty per cent of hand function. It gets its own phase.
  2. Thumb-base arthritis loves the muscle beside the index finger — that one is trained every session here.
  3. Pinch is trained in a stable position: the thumb pad presses, the joint does not collapse.
  4. Dexterity is a skill. Practise it slowly and accurately before practising it fast.
