Flexor and extensor exercise device
An exercise device that exercises both flexor and extensor muscles. The exercise device includes a base. First and second sidewalls upwardly extend from opposing sides of the base. Each of the first and second sidewall has a plurality of teeth formed on an upper rim extending from the front end to the rear end of the base. At least a first gear is secured to a first end of an elongated rod and at least a second gear is secured to a second end of the elongated rod. A plurality of teeth of the first gear interlock with the plurality of teeth of the first sidewall and a plurality of teeth of the second gear interlock with the plurality of teeth of the second sidewall. A board rests on the elongated rod in between the first end and the second end.
