Hand Adduction With Extended Elbow.

Muscles involved: Extensor carpi radialis longus, abducens policis

Instruction:

Preferably standing up, extend the elbow completely and while keeping the hand adducted (the little finger is brought closer toward the forearm) press on the area of the thumb with your opposite hand.

Commentary:

By keeping the elbow extended you are working all of the target muscles, otherwise we would be focusing too exclusively on the muscles of the fingers. Let’s not forget that some of the muscles being stretched in this exercise are bi-jointed, meaning they cross both the elbow and the wrist.
