I tried to run. I really did. I warmed up for five minutes, like the program instructs. Then I broke into a SLOW jog. I'm talking 5.2 mph on the treadmill. I was able to keep it up for 1/8 of a mile.
Why? Not because I was tired. Not because I was out of shape.
My damn shoulder hurt.
I guess I'm still not ready to run :-(
Ended up walking for 30 minutes, with an incline ranging from 3.0 to 9.0.
