|Utility:||Basic or Auxiliary|
Sit on seat and position forefeet on pedals. Grasp handles to sides and straighten knees.
Push left pedal by extending ankle as far as possible while allowing right pedal to return back until calf is stretched. Reverse motion by pushing right pedal and allowing left pedal to return back. Continue to alternate motion.
Position seat to allow full range of motion. Reposition stance if feet slip. Keep knees straight throughout exercise or bend knees slightly only during stretch. Quadriceps serve as synergists muscle if knees are bent slightly during stretch. See Calf Exercise Analyses. Also see Lever Alternating Bent Knee Calf Extension.
