I've heard of things like the "runners high". Somehow getting a second wind that pushes you through, getting an adrenaline rush that makes you feel great and ending a workout on a high note, feeling like you could keep going or use that energy to go do something fun now.
But it's never happened to me.
Holy Crap! I was at my Zumba class, and it was about 45 minutes in (it's a 60 min class). One song ended and when we started the next one... it was like I had a second wind! Instead of dragging, like I often do 45 min into the class, I started picking up my pace. I could do the moves along with the instructor, and with a bounce in my step! I was still sweating, but it felt great. I couldn't believe it. I have never felt this before, and it was amazing.
After class, I felt energized, like I wanted to go out and do something fun. In the parking lot, I was almost in tears. It's the little things like this that give me so much HOPE. That keep me on track. That remind me why I'm doing this, why I'm pushing myself. I am proud of myself for sticking with this. It's been 10 weeks and there's no way in HELL I'm stopping now!
