Challenge day ... who cares!

I did exercise last night, but not tonight. My sister & a friend at work got me started on a new fitness app called My Fitness Pal. It's free and super easy to use, but it keeps reminding me that I am eating to much and exercising too little. Last night I did 160 crunches and 5 minutes of step ups on a 10 inch box - ouch! My butt hurts tonight!!! With this much pain my butt should be rock solid ... it is not.
