We have plenty of thoughtful readers who use weight-lifting as a part of, or as the entirety, of their fitness programs. That is one of the cool things about an eclectic website.
I take all of your comments on fitness topics seriously.
Clearly, upping my routine after a few months of just running and calisthenics was part of my DOMS. What my genius trainer did for me this morning was to run me through ten minutes of leg stretches and light Tiger Tail rolling before we went to bench press. The pain disappeared.
Go figure. He suggested a heat pad for 10 minutes, then some light Tiger Tail. And yes, he blames it on getting back to more intense work. My pre-April routine was disrupted by gym closure, road running instead of treadmill and stair machine, a week's vacation, and do-it-yourself calisthenics (sadly, not as intense as gym classes). I had been doing 3 days of weights, 1-2 days of calis, and 1-2 days of HIIT cardio. No problems.
