Our external environment no longer seems to have any firm boundaries, any limits, or any positive cues about when to stop consuming anything. I mean, there is a reason that people get fat - it's easy and cheap to get high-calorie, tasty food.

I really believe that our past can really hold us back from growth, so the best thing that we can do is MOVE ON and NOT DWELL.

CrossFit is all about constantly-varied, high-intensity movements. And to do these movements, you have to have a certified coach to take you through this - or any type of physical activity.

If you're wanting something salty, do air-popped popcorn. That, to me, would be a healthier choice than having any kind of fried chip.

It just kills me when people buy a dog when there are dogs in shelters. I still get emotional when I think of Karl sitting in that shelter. I wasn't looking. I didn't even think I had time for a dog, and then I met this little one and he needed help. It's been so amazing to see him transform into a happy and confident companion.

Jessica Alba to me is on the top of the food chain. She's gorgeous, she's smart, and she really takes care of herself. I think that she looks great. I think that as Jennifer Aniston gets older, she looks better and better, and I really like that.

Since I started CrossFit, I've read and heard about the critics talk about how unsafe it is, and my only response to that is any form of exercise can be unsafe if you don't have the proper coaching, education and guidance.
