2013-2014 Exercise Challenge

[Crankin]

I'm wondering how to denote partial hours... like today I did 45 minutes of treadmill hill walking and strength/stretches. I'm assuming .5, .7, etc. Catrin, maybe my poor math skills are showing, but if you want to do 6 hours a week, that's 12X6==72. You really want to do 165 hours??? I put down 100, knowing that some weeks, I'll do more, but it might be closer to 70.
