This was made all too clear to me today during my first workout after school. We have nationally certified cross-fit instructors on our staff who offer all interested staff and students free cross-fit training after school. Our school nurse has been encouraging me to join for the past couple of weeks, and with my family a bit more established into a schedule, I decided to start.
And as a result ... I hurt. A lot.
Now, I've been told by a number of people that it will get better as my body gets used to this torture, but there is certainly a part of my brain that questions whether they are lying to me out of revenge for some unknown slight on my part. That said, if I want to outlast zombies (or even the next few decades), I need to work on making my body more of a temple and less of a ruined shrine.
