The present invention relates to a practice golf club capable of adjusting head speed having a head (H) attached to an end of a shaft(S) having a grip (G), from which an impact sound is generated through a swing operation, wherein the head (H) includes: a first body (100) coupled to the end of the shaft (S); a second body (110) having a tubular shape, both ends of which are open and adapted to be screw-coupled to the rear end of the first body (100); a moving weight (140) movably disposed inside the second body (110); a magnet (180) adapted to fix the moving weight (140) to the front end portion of the second body (110) by means of a magnetic force thereof; adjustment means adapted to adjust the gap between the magnet (180) and the moving weight (140) so as to control the strength of the magnetic force of the magnet (180) pulling the moving weight (140); a cap (120) screw-coupled to a rear end of the second body (110); and return means interposed between the cap (120) and the moving weight (140) to return the moving weight (140) to the original position when the moving weight (140) momentarily moves by centrifugal force and collides against the cap (120) to generate an impact sound.
