Finger Flexion While Extending Thumb
A hand-control drill: the four fingers curl into the palm while the thumb straightens away from them, the hands resting on a table.
How to do it
Setup
Standing at a table or box, both hands flat on top, fingers together, thumbs relaxed.
Steps
- Curl the four fingers in toward the palm.
- At the same time, straighten the thumb out to the side.
- Open the hand flat again and repeat slowly.
Common mistakes
Thumb curling in with the fingers: it moves the opposite way. Lifting the whole hand off the surface: the heel of the hand stays down. Rushing the pattern: slow and exact beats fast.
Breathing
Easy and steady.
