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.

I found that people like rules, and I love to tell people what to do. It's not rocket science when it comes to weight loss. It's about eating a little less and moving a little bit more.

If you want to be right-sized in body, you've got to get rid of the supersize way of life.

The CrossFit program is broad, general and inclusive, and most of all, the movements can be scaled down to any level of athlete. Just watch what I do with it on 'The Biggest Loser.'

Try a recipe that uses leafy vegetables like kale, or switch to filling, high fiber grains like whole-wheat pasta.

Believe in yourself. Trust the process. Change forever.

There's no finish line. That's a big pill for people to swallow, Every single day for the rest of your life, you are going to have to make better food choices, and move around a bit more.
