Crunched My Back

No cause for alarm, but, apparently 15 crunches two days in a row is too much for me right now. I walked over 200 miles in a little over a month and no problem. After 30 crunches in two days I walked a little funny. So I'll lay off crunches and I'll keep walking. I still believe it's better to not push quite as hard and keep yourself healthy so that there is no recovery time. I simply didn't pay as close attention as I should have. Maybe there's a lesson here?

I am walking. You can walk. Please walk today. No matter what.
