Didn't want to but did

Last night Shawn and I both struggled with going to the gym. It was one of those nights when you get home from work and your just ready for bed. We pushed ourselves out the door and to the gym. I think I had my hardest treadmill workout yet last night. I did what is called Zone Training. The treadmill tells you what your goal heart rate is and when you reach that it gives you a new goal and increases you incline to make you work harder. The first heart rate was 124, then 134, then back to 124, then up to 144, then back to 124, then it was supposed to go up to 154, but my time ran out and I did my cool down. I felt like I really had to work hard to make it. I was thinking about it this morning and how scared I have been of the treadmill. I honestly think before I started I thought it would literally kill me to workout on a treadmill. To my amazement, I haven't died yet. :-) Tonight I do 28 minutes so we will see if I make it. :-)
