Article: The brain-changing benefits of exercise
Speaker: Wendy Suzuki
...
I went to kickbox, dance, yoga, step class, and at first it was really hard.
But what I noticed is that after every sweat-inducing workout that I tried, I had this great mood boost and this great energy boost.
And that's what kept me going back to the gym.
Well, I started feeling stronger.
