My couchsurfing hosts have one of the exercise machines that inspired my HPV: a stairstepper combined with vertical poles to push and pull with the arms. Since in this, but not my HPV design, the arm poles are not synchronized with the feet, I was able to try the different combinations. I found that, for me at least, pushing out with one arm while pushing down with the opposite foot feels more correct, and feels as though I'm getting more total power output. That will determine how I build the linkages.
