The Science Behind Thumb Strength
What happens in the muscles of the thumb when we exert force? Science shows that the thumb relies on a network of muscles and tendons to function. These muscles work
The muscles of the thumb work in tight concert, pulling and holding with a precision that few other digits can match. Opposing this is the extensor pollicis longus and extensor pollicis brevis, which extend the thumb against resistance. The flexor pollicis longus and flexor pollicis brevis bring the thumb into a flexed position, while the adductor pollicis pulls it toward the hand. The nuanced web of tendons, pulleys, and the thenar eminence’s tiny yet powerful muscles allows a single thumb to grip a golf club, manipulate a pen, or press a key with equal ease.
And yeah — that's actually more nuanced than it sounds.
Training Principles for a Stronger Thumb
