A training device for use by a lacrosse player to practice checking an offensive player includes a main post extending upwardly from a base. An arm is operatively coupled to the main post and rotatable about a fixed point intermediate its proximal and distal ends. The arm includes a wrist near its distal end for holding a lacrosse stick. An activating member is mounted to the main post for separating a user from the arm's distal end. An actuator is coupled to the arm's distal member and to the activating member such that the arm is caused to move when a user attacks the activating member. The actuator may include rack and pinion gears for translating a linear force upon the activating member into a rotational force upon the arm. A spiral spring and cam provide for oscillating movement of the arm.
