Endorphins

Recently my husband added me to his gym membership. Today was the first day I went. I did 40 minutes on the treatmill at 3.5 mph at a #3 incline.
When I finished, I felt so great. It was like I had slept 20 hours none stop. I felt refreshed. I felt invigorated. I felt "high". It was very strange.
I know exercise can do that, but it's the first time I have ever felt that way.
It was a great feeling and I can't wait to go back. The people there were friendly and helpful. They have everything there you could possibly need. Its a great facility.
