Abstract: A tennis training device comprising a first arrangement surrounding a selected one of a upper arm above an elbow of a tennis player and a lower arm below the elbow of the tennis player; and a second arrangement connected between the first arrangement and a tip of a tennis racket head held in the hand of the tennis player to produce a classic tennis stroke from an early lower preparation to a high and complete follow-through while correctly positioning the associated shoulder, the arm, the elbow, the associated wrist and the hand of the tennis player relative to each other during the classic stroke.

Abstract: A tennis training device comprising a tennis racket with its usual strings; a pair of rods each disposed on a different side of the strings adjacent a sweet spot of the strings; a first arrangement extending through the strings to detachably secure the pair of rods to each other; a predetermined number of spherical objects each having a predetermined diameter skewered on each of the pair of rods; each of the pair of rods having a length equal to the predetermined number times the predetermined diameter; and a second arrangement attached to an end of each of the pair of rods remote from the strings to hold at least one of the associated ones of the spherical objects in contact with an associated side of the strings; the spherical objects enabling development of visualization phenomena of the spherical objects hitting the sweet spot and simultaneously developing muscular control, muscule memory and muscle strength of grip, wrist, lower arm, upper arm and shoulder when repeatably simulating all actual tennis str
