A Quote by Jack LaLanne

Muscle cells strengthen in response to intense exercise - whether you're 18 or 88. But the intensity is what's lacking in most people's workouts. And there are doctors who'll give you the advice, "Well, don't push it."
My training centered on aerobic development, meaning I'd swim longer with less intensity during the majority of my practices. As I got older, I began more weight training, and my workouts went from long at a lower intensity to shorter and more intense.
I can bulk up very fast. I can lift heavy weights because, like most people, I started off with heavy workouts. That's stayed in my muscle memory. I feel horrible when I feel my jeans are getting tight. Workouts peace me out.
My workouts include aerobic exercise for a healthy cardiovascular system; strength training to maintain muscle tone and bone density; core strength exercise for a stable mid-section; and stretching to maintain mobility.
What the hell do doctors know about exercise? Most of them know zero. You gotta push elderly people to failure like anybody else. Then the body responds.
What is wrong with looking muscular? Muscles are beautiful. Strength is beautiful. Muscle tissue is beautiful. It is metabolically, medically, and philosophically beautiful. Muscles retreat when they're not used, but they will always come back if you give them good reason. No matter how old you get, your muscles never lose hope. Few cells of the body are as capable as muscle cells are of change and reformation, of achievement and transcendence.
My favorite thing do is HITT workouts, or high interval intensity workouts. like to do that because I'm not really a cardio person.
Sunday-the doctor's paradise! Doctors at country clubs, doctors at the seaside, doctors with mistresses, doctors with wives, doctors in church, doctors in yachts, doctors everywhere resolutely being people, not doctors.
Kenneth Cooper's research shows that low to moderate intensity exercise is just as beneficial as high-intensity exercise - but without the rigorous wear and tear on the system.
Now I usually try not to give advice. Information, yes, advice, no. But, what has worked for me may not work for you. Well, take for instance what has worked for me. Wigs. Tight clothes. Push up bras.
Cardio-based exercise involves moving at a moderate intensity, using many muscle groups at once. Think: walking, jogging, cycling, etc.
Most of us have just learned to exercise our survival muscle. It's time to build our victory muscle.
I cannot give any scientist of any age better advice than this: the intensity of a conviction that a hypothesis is true has no bearing over whether it is true or not.
I do a lot of weight training, and my workouts are intense, which include cardios, core body workouts, and functional training.
When I want to push myself and do intense workouts, I do that, but I'm not going to do it because anybody thinks I should look a certain way. It's really more about how I feel and about being healthy.
We proved that we could increase laser intensity by orders of magnitude. In fact, CPA led to the most intense laser pulses ever recorded. Our findings changed the world's understanding of how atoms interact with high-intensity light.
Intensity is a mental attitude more than a physical attitude. Many people misunderstand what intensity means. They think it means straining and sweating. No! That is a wrong meaning of the word! Intensity is to get totally involved, fully immersed and absorbed in what one is doing. Intense practice means a fast and keen mode in adjusting, correcting, and progressively proceeding.
