Pulled left calf muscle healing, but again tackling the treadmill, I felt a twinge in my right calf and immediately eased off. I'm hoping this is building strength, and as long as I don't injure the muscle, I'm strengthening it.

It is discouraging, but it is a reflection on my failed effort to try to run again last year. I recognize now that my calves are woefully weak, and they simply failed last year and I simply gave up, fearing further injury. I already injured one this year, but with the controlled environment of a gym, I can focus on babying my calves up to strength as long as I avoid injury. And icing after stopping after feeling the muscle getting to the brink of tearing.
