First of all let me say third time around on an Explorer seems to have worked..Best guts of any machine I ever used however killed my back..It seems careful setting of the lower rod and armrest so your arm hangs straight down and you glide the coil over the ground works for me relative arm and shoulder fatigue..Seems like I had the lower rod a tad short and was actually bending which caused a back problem which has plagued me for years. Had a fellow check me out and made it longer so I was standing straight and two times out seems to have cured all my problems. For those that have a good back might want to try Doc's harness as feedback seems to be great as it takes weight off the arms and shoulder and transfers it to the larger back muscles for long hours in the field..Seems like I am good to go and at 67 surely no weightlifter so you might want to experiment a bit yourself.
