I just cant run on pavement any more. Am I being a pussy or is this just naturally aging shit? I'm 23 years old...5'8.. 170.. ~13-14% BF Heres why I made this thread: Last week I did 1hr cardio / 4 days in the Gym - drove to the gym No pain when running Yesterday I ran to the gym and did cardio in the gym Today i drove to gym and tried to run on treadmill.. and.. i was in some 7/10 pain. What the fuck?! Did the concrete/pavement do that much damage yesterday? For clarification, its just pain in my legs/joints/shin Whats F&N's take on this. Do i need to just run treadmill / track / beach from now on?
