Yesterday was my first day back to my trainer in two weeks and today I am having trouble sitting down. It doesn't hurt once I'm seated, but on the way down my butt muscles start complaining like you wouldn't believe.
It hurts much less than it did the day after my very first training session. Back then I couldn't sit down without holding onto something. I was just leaning into my car and basically falling into the seat because my muscles hurt too much to use. So my pain today is sort of a triumph in that it is so much less.
