Finger exercises can be done almost at any time.  Your fingers themselves don’t actually have muscles as such within the actual fingers. The muscles which are used to bend the fingers are actually found in your palm, and also some are in your forearm. They are connected to the finger bones by your tendons, and which pull on and move the fingers like the strings of one of those old puppets that some of us remember from long ago. The ones that remotely controlled the limbs of the puppet by the operator pulling on long strings, but who was always hidden somewhere behind the scenes.  Here is a video of thumb exercises brought to you by Max Superspecialty Ortho Clinic
