CYCLING ADVICE FROM A WINDOW PAINTER

Do you want stronger cycling legs?   Buy one of these and step up and down on it 3 to 4 hours a day. 
Myself  during Christmas were talking about 6 to 9 hours a day. 
I'll be honest it my time on it can vary, but 3 stores in one day that 8 to 9 hours. 

Twin City flooring is a two day project.  So a total of 18 hours of none stop up and down.
