A treadmill is probably better for your knees too.(Because of shork absorbment)
Though running on a treadmill is easier than normal running (less air friction) so you either have to run at a higher pace or longer.
Treadmills with even more shock absorbment are even better for your knees.
this is the problem i have with running
my coach cant see that running kills my legs
and my old knee injury and 240 body weight does not help
by the way my coach fought at 118 lol
