I've never done yoga, so I don't know about that! But I'm like the absolute last person to cry at anything and a few weeks ago I was running sprints on the treadmill and got it up to 11.0mph and as soon as I stopped I felt like I was going to burst into tears. It was the weirdest thing. I have no idea why it happens! Haha. My guess for me was that the exercise was
so intense for those few seconds anything I was too exhausted to keep things bottled up any longer.
I didn't feel like I had anything bottled up though...

It was weird to say the least!
