The setup is simple, get working on a steep to very steep hill climb. It is important that steepness of the hill requires pedaling to move the fly wheel. For visualization one starts a Fisherman’s Wharf in San Francisco and goes up Lombard St. (18% grade) and/or Filbert St. (31 % Grade!). The variation is there are Street Light and one must stop pedaling when the signal is RED. Call Red Light and wait 5 – 10 seconds and then call Green Light. The trick is to stop you pedals in the 3 and 9 o’clock positions. Repeat “Red light” intersections 5 -8 times. A real strength builder.
