Sustained Open & Close

A sustained open & close built around steady, repeated opening and closing.

Tool: Finger Stretcher

Benefits:

Daily: Looser, more responsive hands
Training: Sustained open–close builds extensor endurance
Comfort: Controlled range reduces stretch discomfort

How to:

Set Up: Choose a comfortable resistance and range on the finger stretcher
Do: Even open–close cycles (6–8) → controlled return

Equivalent logic:

Best with a finger stretcher; unweighted works if you keep the same slow, comfortable range

Safety:

Stop for sharp pain, numbness, or tingling
Stay in a comfortable range
Stay controlled
