Get To Know Your Personal Coach
What’s your go-to workout jam or favorite hype song?
My favorite workout jam has to be "Lose Yourself" by Eminem. It gets the job done every time!
Where would you rather be?
It might make me sound like a kid, but I’d rather be outdoors at play. I always feel rejuvenated after playing a sport, exercising in the foothills, or just running around like I am back on the playground.
What’s your cocktail of choice?
My favorite drink has to be an Old Fashioned or any of the prohibition-style cocktails. I guess you could say I drink like an old man.
What has you smiling?
Nothing makes me smile more than a great comedy special.
What’s your guilty pleasure food after a tough workout?
That’s an easy one. My favorite guilty pleasure food after a workout is definitely an In-N-Out burger and fries.

"I’m pretty sure there’s more to life than being really, really, ridiculously good-looking. And I plan to find out what that is." – Derek Zoolander
