Physical fitness is not only one of the most important keys to a healthy body, it is the basis of dynamic and creative intellectual activity.

Vitality shows in not only the ability to persist but the ability to start over.

It was actually drumming that gave me the stamina to get into sports later. I started playing drums at 13, and when I got to the international touring level... I got interested in cross-country skiing, long-distance swimming, bicycling... things that require stamina, not finesse.

To resist the frigidity of old age, one must combine the body, the mind, and the heart. And to keep these in parallel vigor one must exercise, study, and love.

Endurance is the crowning quality, And patience all the passion of great hearts.

But I always had in built strength. I used to do like push ups for three hours. It's building up that core fitness and stamina.

Fitness has always been one of my strengths. I can do all the long-distance runs. When I was at school and we entered the competitions, I used to do the 100m, 200m, and the 1500m as well, so it's never just been a pace thing.

Eventually, competition and adventure wane, and I enter my ibuprofen phase. Tweaky hamstrings and achy knees restrict mileage, but I continue running for health, sanity, and the ritual of a Sunday trail run with like-minded buddies. We discuss the nagging injuries that bedevil us, and remember the good old days when we were kings.

People assume that you need to run fast to get to optimum fitness, but the truth is endurance lifting makes you stronger and leaner.

Burning desire to be or do something gives us staying power - a reason to get up every morning or to pick ourselves up and start in again after a disappointment.

Endurance is nobler than strength, and patience than beauty.

Enthusiasm... the sustaining power of all great action.

Our fatigue is often caused not by work, but by worry, frustration and resentment.

The resistance that you fight physically in the gym and the resistance that you fight in life can only build a strong character.

Great works are performed not by strength but by perseverance.

Endurance is patience concentrated.

Wondrous is the strength of cheerfulness, and its power of endurance - the cheerful man will do more in the same time, will do it; better, will preserve it longer, than the sad or sullen.

Qualities you need to get through medical school and residency: Discipline. Patience. Perseverance. A willingness to forgo sleep. A penchant for sadomasochism. Ability to weather crises of faith and self-confidence. Accept exhaustion as fact of life. Addiction to caffeine a definite plus. Unfailing optimism that the end is in sight.

Patience and time do more than strength or passion.

It is not easy to participate in the 21 km. marathon. It takes a lot of energy, determination, and will power. It takes months to train to reach that mark with a proper diet chart.

Strength and growth come only through continuous effort and struggle.

The first virtue in a soldier is endurance of fatigue; courage is only the second virtue.

Exercise is labor without weariness.

My stamina was my strength.

Beyond racing, I just love the art form of running, of conceiving new ideas like the 50 Marathons in 50 States in 50 Days. It's the ultimate expression of what I love to do, which is run, and travel, and see this great country.

Endurance is not just the ability to bear a hard thing, but to turn it into glory.

For me fitness is not about fighting fat or aiming thinness, it is about having the stamina and physical energy to keep up with my professional demands and day to day requirements of life.

For to be poised against fatality, to meet adverse conditions gracefully, is more than simple endurance; it is an act of aggression, a positive triumph.

So I've broadened the fitness concept to make it one of moderation and balance.

When you have a certain fitness projection, it's going to give you an advantage. Having strength, stamina and speed is important because I'm working with dogs who can kill me.

Regularity in the hours of rising and retiring, perseverance in exercise, adaptation of dress to the variations of climate, simple and nutritious aliment, and temperance in all things are necessary branches of the regimen of health.

Fitness is a curve. You can be Lance Armstrong, or you can be really out of shape at the opposite end. People enter the curve wherever they are and then they can move up the curve, by better nutrition and better exercise.

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.

Continuous effort - not strength or intelligence - is the key to unlocking our potential.

Making fitness a priority will energize you, make you look and feel better, and help diffuse stress.

For Le Mans, you still have to keep fit, it's endurance. It's a different type of fitness. You want to actually fit in the car - the seats are ridiculously small.

Great is the power of habit. It teaches us to bear fatigue and to despise wounds and pain.

Patience, persistence and perspiration make an unbeatable combination for success.

Patience, persistence and perspiration make an unbeatable combination for success.

Perseverance is also key to success in any endeavor, but without perseverance in combat, there can be no victory.

Permanence, perseverance and persistence in spite of all obstacles, discouragements, and impossibilities: It is this, that in all things distinguishes the strong soul from the weak.

Believe me, my children have more stamina than a power station.

I think I got stamina from my dad, although he didn't have a lot of drive.

The men who learn endurance, are they who call the whole world, brother.
