A football lineman trainer has a frame supported on runners between which rollers are positioned for control through foot pedals by an operator on the frame to vary the resistance to movement of the trainer as linemen contact individual pad units which can be set and locked in low, high and intermediate positions or can be moved from and into such positions by the operator through a foot pedal assembly so as to teach different techniques for both defensive and offensive linemen with the pad units being separately adjustable from straight up to approximately 30 DEG leaning positions with such positions being sustained at the various low or high placements and movements of the pad units which are designed for face blocking as well as shoulder blocking.
