I've been running for years, but I just started doing yoga this past summer. I guess I was a little skeptical of yoga because people only say amazing things about it. I just didn't believe any one thing could really be that great. I'm not about to tell you that yoga changed my life, but it definitely changed my running. Here is how:
Mind set- Right off the bat, I started thinking more about the intentions I had for each of my runs. This has helped me stay motivated.
Posture- I never thought about my posture while running until after I started yoga. Maybe other runners think about this all the time, but not me. Keeping my shoulders back and thinking about what part of my body I'm "leading" with has reduced cramps and helped me push more easily through hills.
Speed- The craziest part is, any time I run after doing yoga, I am a lot faster. I honestly feel lighter on my feet. Very strange, but I'm not going to knock it!
So... Yoga + running= fast runs, with fewer cramps, stronger hill running, and a better mind set= Yes!
