Bob Harper quotes:

When I was first introduced to CrossFit, I found it to be the hardest workout that I'd ever done. It wiped the floor with me, and I fell in love with it immediately. The results that I have seen in my strength and physicality have been unparalleled to any other things I have ever done in my more than 20 years in the fitness business.

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.'

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.

Even though you really don't feel like you're motivated to go to the gym, remember how good you felt after the last time you went. Keep that in the forefront of your brain.

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.

You can't be a parent and say, 'I need you to be more active and I need you to eat right,' when you're still choosing to have poor eating habits.

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.

Whatever the parents are doing, the kids will follow suit.

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.

When I came out, when I was 17 years old, it was one of those things where I realized that there was going to be so many obstacles, but being gay doesn't mean being weak.

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.

Stand up and finish what you started

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

It's the fact that no matter how bad it's gotten, the body wants to be healthy. The body wants to bounce back. When you do these changes, you do these small changes every single day, and you trust the process of what you're doing. You really do make lasting changes onto your body.

Stop talking about tomorrow. You owe it to yourself to do whatever you can to live you can to live a better life today.

I believe in the power of the human spirit.

I don't want anyone to ever put himself or herself in a box of, "I lost my second chance!" Because life brings you ebbs and flows, and if you miss out on this second chance, guess what, you're going to get another one if you decide that you're ready to have one.

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.

By default I am the good parent. I've used my own personal experience. I came from a world where I was in need and starving for the good parent, so it's like I'm bringing my own persona issues into that. I am the parent that I always wanted to have; that's how I look at my role.

I'm tired of good people getting ripped off by diet products that don't work!

Being gay doesn't mean that you are less than anybody else. It's just who you are.
