I am so thankful for exercise. Not necessarily in the middle of a minute of squats or burpees, but I am grateful that it helps my body work as well as it does. I am grateful to feel the soreness of stiff muscles that have been worked, because...well, I have muscles that can work! Over the past year of building a house, my exercise was without much intense effort. I did it, but I hated exercising in the dingy rental basement. Turns out I didn't push myself too hard. It feels good to get back to intense effort.
