A unilateral leg press exercise machine is provided. This machine includes a base frame, which is engaged with the floor. The base frame includes bottom side supports, bottom front and back supports to provide stability to the machine. The base frame also includes two sliding carriages which hold resistance plate holders and move in a straight line at an angle of approximately 20 degrees to the floor. 2 resistance plate holders are attached to each moving carriage for a total of 4 and provide the desired weight resistance during the exercise. An adjustable back pad is provided to vary the angles to approximately 15 degrees from the horizontal floor. A set of adjustable shoulder pads on the seat hold the user in place as the back pad is lowered to angles that are closer to the horizontal position.
