So using a 2.0 cyclometer at like 5/6 inches of mercury I just find I can’t tolerate higher pressures. Will you still see progress at this lower pressure. Usually use 2.125, if I’m just interested in length is this the narrower cylinder best?
Started back up again after 10 weeks off do 40 mins hanging before pumping. Any tips advice would be great
