Our Pro-Fitness.com PF284 Plate Loaded Standing Calf Raise is an excellent machine from the beginner to the most serious lifter. Incredibly smooth action is achieved through the use of oversize pillow block bearings at the pivot point. Over 26" of plate loading capability and built in negative leverage allows the lifter to overload the muscles of the lower leg. Heavy duty shoulder support pads provide for shoulder comfort throughout the exercise movement. This machine is completely adjustable to accommodate most size lifters.
