First Workout in 6 Months

Yesterday I had my first workout. I really did not want to go to the gym after work and while I was driving, the whole time I was debating whether to go home or just get the workout over with. I decided to just go and work out. After getting out of the car and into the locker room I changed and walked over to the mirror to put my hair up. When I looked in the mirror I wanted to scream! I still can't believe I am 160 but this time I saw it in the mirror. I was totally discussed and glad i decided to go to the gym. I got my butt out onto the floor and decided today would be a cardio day. For 50 minutes I did tread mill, the precor ( this machine is an elliptical and stepper in one), and the bike. I did have a little trouble on the precor because my knee started to hurt but I said ok body I'll get off this for now and come back a little later. One thing I have to remember is listen to my body. There is exercise pain and then there is real pain. Exercise pain is the "Oh my gosh I'm going to puke if I do anymore, that is when you push yourself a little further then stop. But real pain is more sharp, like my knee hurting yesterday. After going home, I was exhausted and desperately needed a shower. My body did feel tired and to be honest I was glad I could feel my workout. This meant i was moving the right direction. I was also starved and may have made a bad choice with eating but I let it go and didn't indulge to badly. I also slept like a baby last night, I did wake up once but it was so easy to go back to sleep.
