The only way for a rich man to be healthy is by exercise and abstinence, to live as if he were poor.

Resting for me is fitness training.

For a good workout, I go to At One Fitness in North Hollywood, where my trainer, Jon Allsop, puts me through it all. I like it because it's a small gym and I've known the people for a long time. Jon will have me do cross-training where I'll lift weights, jump rope, throw around a medicine ball and I never get to stop.

What you want is to rev up your metabolism so that you are burning fat and calories, not preserving fat and calories.

And I believe that the best buy in public health today must be a combination of regular physical exercise and a healthy diet.

I feel if I'm healthy and happy, I look good. With a good mixture of fitness and healthy food I always feel great!

As a longtime practitioner of yoga and a person who's been involved in physical fitness my whole life, I can tell you, yoga helps you achieve altered states of consciousness. It is not just stretching. The only way you can say that it's stretching is if you haven't done it, or that you haven't done it rigorously for a long period of time.

I know April, May and June are a few unbearable months, and working out in a gym and sweating in such dirty hot, sticky, humid weather puts me off. The best way is to swim. I feel so fresh and rejuvenated after swimming, and I believe it's one of the best mode to fitness during summers.

I swim like a fish and I have an amazing kick.

Our children are obese, either have or being threatened by diabetes, high blood pressure, high cholesterol, and not socially adjusting properly to others because of a lack of fitness.

I am 5 ft 6 in, and at my peak, my vital statistics were 37-22-35. I didn't even think about my weight - but now I work hard at keeping healthy. Fortunately, my husband Richie is as much of a fitness buff as I am.

I'm French, so I'm quite lazy about exercising, and I smoke. But I do love going for a run in the morning with my dog. That's all.

Like most people I can be lazy, so it's nice to have a goal or deadline or reason to work out. I feel better when I get to exercise, or when I'm outdoors. I like to hike, swim and run, and I love to play soccer.

A drunkard in the gutter is just where he ought to be, according to the fitness and tendency of things. Nature has set upon him the process of decline and dissolution by which she removes things which have survived their usefulness.

Cycling keeps me lean and I need to stay in shape, especially as I still like eating chocolate and ice-cream! I like to go mountain biking too. Running is also good; it's what we were designed to do as humans, so it comes naturally.

When you get into the final week of the Tour de France, it becomes a different kind of race. As the distance and the fatigue really tell, that is when it becomes a proper test of everyone's fitness.

Exercise is labor without weariness.

I can work hard and be disciplined like a soldier, but I could never reach their level of fitness.

Never hurry. Take plenty of exercise. Always be cheerful. Take all the sleep you need. You may expect to be well.

Exercise is the chief source of improvement in our faculties.

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.

No one's ever achieved financial fitness with a January resolution that's abandoned by February.

When you're singing, you're using extra muscles, and it requires a lot of exercise and breathing. You can't do that if you're a sissy. If I have any fitness advice for people, I'd tell them to sing more. It's good therapy, too.

There is a moment when you get older when your metabolism slows down and you don't feel like working out any more, so you don't want to keep yourself fit any more, but that's your decision. Why should you be judged for it?

Fitness has always been one of the top priorities in my life because that's the way I grew up, with soccer being the sport of choice.

Staying more controlled mentally stemmed from taking my fitness more seriously. When you're doing track work, sprints and so on, it's pretty painful, but that does make you feel better prepared and therefore mentally stronger when you're going into a match. You know, without a doubt, that you are strong enough to last.

I've been into exercise my whole life, been a runner and been into health and fitness always.

As a father, my first priority is to help my sons set and attain personal goals so they will develop self-confidence and individual strength. Engaging in regular fitness activities with my children helps me fulfill those responsibilities.

Just as you can't blindly follow fashion, you can't follow fitness, either.

Guided only by their feeling for symmetry, simplicity, and generality, and an indefinable sense of the fitness of things, creative mathematicians now, as in the past, are inspired by the art of mathematics rather than by any prospect of ultimate usefulness.

Compared to my physique before pregnancy, yes, I do feel different. I have worked really hard and changed a few things - not only my fitness regime but also my nutrition. When I think about it, being pregnant definitely helped my physique.

I can jog, but I can't run. That's hard for me. I like the fact that I can jog for fitness, but to me there's a huge difference between jogging and running.

Fitness is defined differently by everyone, but for me, the most important thing is being healthy. As tennis players, what we do is not the healthiest thing. We almost abuse our bodies.

With both kids, I started working out again at 16 days postpartum, but I treated myself with kindness, doing mild workouts, because my fitness level was lower.

In terms of fitness and battling through cancer, exercise helps you stay strong physically and mentally.

I am about to get involved with the biggest cancer hospital in Norway. They are building a fitness center to work with patients. I will be a consultant.

I do yoga, I do Bikram and I run, and I eat really healthy.

It takes about four days of virtuous living to create a little weight loss. That also happens to be the time required to get used to eating less. In other words, if you can get past day three of a fitness regimen, things improve.

We took advantage of the running boom, which became the jogging boom, which became the fitness boom... and we've benefited from all of that.

I'm not a fitness model; I'm just a singer. If people focus on that, that's what I care about.

I think it'd be wonderful if we could train young girls to be active in lots of ways and that they then wouldn't have to age at the same rate that they would if they were not more active. In other words, more physical fitness and not just the sporty kind, but the yoga, which is really important.

All we're trying to do is change how people think about fitness. And build Under Armour into the biggest brand in the entire land.

You gotta have a body.

The funny thing is, we teach - as a culture, we teach people that it's OK to talk about your fitness goals... Like, I want to be more physically fit, I want to drop 10 pounds, but no one's talking about how I can spend 10 days to get happier.

I try to come at fitness and nutrition from a perspective of gentleness and what will make me feel good afterwards. I try to stay out of the mindset of needing to fix myself. I do whatever seems fun to me.

My morning starts with some form of exercise, and I give two hours - from 5:30 to 7:30 A.M. - to my personal fitness.

Obviously, when you're doing fitness work at a club all week and every week, it's all about specific drills for what you need to do on the pitch. So I'd be doing a different drill to the centre-midfielders. It's all specifically tailored for me. For example, my drills are high speed. It's all about trying to break the line with a sharp sprint.

I've been into fitness since I was 13.

I can't eat whatever I want, definitely not. I'm always controlled because I do a lot of fitness and triathlons, not just Formula One, so I always make sure I eat the right things.

Teaching kids about health and fitness is important to me. It's about being fit for life.
