We completed our second workout this evening. I don't know that it got any easier, but the time seemed to pass more quickly. Also, I didn't get a stitch in my side until the end of the workout and last time I had one half way through. Progress, no?
My muscles still hurt. I'm trying to stretch more. Hopefully they will be stronger soon and not hurt so much.
But I'm not giving up and that's the most important thing.
