Musculi flexores antebrachii · Skupina ohýbačů předloktí
Muscles
Looks like
The muscles on the palm side of the forearm, from the inner elbow to the fingers.
What it does
Bend the wrist and curl the fingers — the power in every grip.
Keeping it well
Warm up and vary the grip; their shared origin is what hurts in golfer's elbow.
