I'm 190 again today....what the heck?

I weighed 190 yesterday and thought it was a fluke.  Then I'm 190 again today...what is going on?  Maybe I was really dehydrated when I weighed 187.5 for a few days?  UGH.

Yesterday's run was awesome - I feel so much better.  Today is a rest day b/c tomorrow I have 'interval' training which is when you go to a track and run 400 and 800 meter faster tempo runs in order to activate and build strength in your running muscles!

Today, I'm gong to do core and arm strengthening exercises.  I guess I could also walk, I need some cardio type exercise to help me burn some calories!
