I managed to bike a year earlier up to 40 miles at a time, but the effect was not lasting, i.e. I had a massive debilitating regression regardless of my will and pain bearing abilities. Only this time as I added so many supplements covering many bases I started experiencing lasting improvement with no major regressions. I also do much less cardio than a 40 mile bike ride, just 30 minutes a day on a rowing machine.
