- Sit on seat and position forefeet on pedals. Grasp handles
to sides and extend knees but maintain small bend in knees.
- Push left pedal by extending ankle knee Simultaneously allow
right pedal to return back by relaxing ankle and bending knee
more. Reverse motion by pushing right pedal and allowing left
pedal to return back by same means. Continue to alternate motion.
- Position seat to allow full range of motion. Gastrocnemius
act as dynamic stabilizers because when they 'contract' at ankle
they are simultaneously 'stretched' at knee. It could be argued
they also act as synergist since bend at knee could be considered
relatively smaller range of motion as compared to ankle articulation
resulting in net contraction of Gastrocnemius. See Calf
