Isometric Hold

Benefits:

Daily: Hold steadier with less shaking
Training: Sustain force at a fixed angle (isometric strength)
Comfort: Controlled endurance without bouncing or cheating

How to:

Set Up: Squeeze to a controllable position (about 60–80% closed), wrist neutral
Do: Reach position → hold still → slow return

Equivalent logic:

Ring and ball — hold a position you can keep still, then return slowly

Safety:

Stop for sharp pain, numbness, or tingling
Slow return — no snapping open
Keep wrists as neutral as possible
