Very tired

I was going to go to the gym after work, but I ended up going to walmart to get some headphones, so I can start listening to my music while I workout.  I ate, way to much for dinner and was resting when I decided that I need to get off my butt and work out.  So I decided to use my big ball that I bought.  I ended up working out for 51 mins and did 100 sit ups, 50 push ups, and 10 mins on the exercise bike.  The 51 mins included some walking and dressing the girls after their bathes.  I am so tired right now.  I guess, even though it wasn't a long workout, it was effective. Well, I got a good work out in and even though I ate way to much for dinner, I still stayed within my calorie range.  So I'm happy about that.
