Breaking a Sweat

I run at the gym at work last night again and I feel so great. Not because I felt that I lost weight but it's because I love it when I break a lot of sweat and catching my breathe when running. I feel like all the bad stuff inside my body is being release.
I really must run at least 2 to 3 times a week to release all those bad stuff inside my body. However, I need to make sure that I drink a lot of water so my kidney will not work hard.
