As a father, my first priority is to help my sons ...

Family involvement is a valuable thing and playing together actively can be the '90s version of it. Instead of just watching, you can do it together... something we don't spend enough time on. We can motivate and excite each other about fitness.

Fitness needs to be perceived as fun and games or we subconsciously avoid it.

My priority is to turn people - especially kids - on to sports and being active so they don't even have to think about it being good for their health. If people participate for the fun of it, and believe me - it is fun, then fitness programs will be much more successful.

We talk a lot on 'Biggest Loser' about how fitness is a natural antidepressant, how it burns off stress. What I like about running is that it gives me time alone. I'm always busy, with people at work, with my kids. I love getting out for a run by myself and just listening to my music.

I personally love to run outdoor fitness trails. I love the meditative value I get when out alone, challenging myself to run faster and higher.

With fitness, I do Bikrams hot yoga. The gym that I have in my building is amazing. I love to do cardio and weights there.

I think exercise tests us in so many ways, our skills, our hearts, our ability to bounce back after setbacks. This is the inner beauty of sports and competition, and it can serve us all well as adult athletes.

Aging is not lost youth but a new stage of opportunity and strength.

Youngsters of the age of two and three are endowed with extraordinary strength. They can lift a dog twice their own weight and dump him into the bathtub.

Brain power improves by brain use, just as our bodily strength grows with exercise. And there is no doubt that a large proportion of the female population, from school days to late middle age, now have very complicated lives indeed.

Old age is not a disease - it is strength and survivorship, triumph over all kinds of vicissitudes and disappointments, trials and illnesses.
