I missed one day last week and I felt it yesterday.  I have to NOT miss any days from now on!  I have been using a printout of the schedule to know what to run since I don't have an iphone to use the app with.  It turns out it wasn't exactly the same as the app but before I ran yesterday I found the actual schedule used on the app.  The difference is what I was using had me walking, running, then walking.  The running part was solid.  The actual C25K has you walk, then walk run walk run walk run...... then walk again.  I tried it the C25K way yesterday and I'm not sure if it was just harder because I didn't do my final run last week or because it's harder to start and stop on the running.  Maybe it's easier just to run for a solid amount of time?  I am going to stick with the real C25K way.  I do wish I had the app though.  I am relying on timers on my watch which is great.... IF I do it right.  I accidentally set it for hours instead of minutes one day last week and thought I was going to die. Then checked my watch and realized what I'd done and I had already ran more than the what I was suppose to.  Yay me! LOL! 

Oh... one more thing.  I did great with my eating habits last week and even lost a couple of pounds.  Then the weekend came.  Baddd weekend.  I gained back a couple of pounds.  Darn chips and queso.  So not worth it.
