yeah well the other day I was pushing barriers by sprinting like a Deer through the woods up down hills around bends over creeks and roots. Pacing my dog that I was following, ill pass her from time to time but I was surprised cuz I haven't ran in like 2 years. No muscle fatigue , hardly huffing and puffing I was good.
