OK, I know, I know....you were all coming in here to read me the riot act about the fact that I lit up a joint or something of the like today. However, Let me assure you that this was NOT the case. For the first time in my life, after I was done doing my cardio, I felt like I was high. I felt totally AWESOME when I got done with my circuit today. My question is this: Why does this happen? I am not a science major, and do not pretend to be, so I am wondering, exactly what happens in our bodies that makes us feel like this? And why doesn't it happen every time you work out? If it did, you can bet that it would be a whole lot easier for people to hit the gym on a regular basis.
