"It is not good enough to have muscle, you must use it!" - Pavel
"Eating alone will not keep a man well; he must also take exercise. For food and exercise, while possessing opposite qualities, yet work together to produce health... And it is necessary, as it appears, to discern the power of various exercise, both natural exercises and artificial, to know which of them tends to increase flesh and which to lessen it; and not only this, but also to proportion exercise to bulk food, to the constitution of the patient, to the age of the individual..." - Hippocrates, Regimen
"For strength and stability, it is necessary to have the feeling that the line connecting the navel and the anus is as short as possible" - Masatoshi Nakayama
"Machine training is often hyped as the thing to do for beginners because free weights are harder to control. The novice beginner must be taught from a base of mobility to progress to stability, just as an infant learns to stand by moving, staggering and exploring the environment"
and again, just because I love this quote
"You’ve got to drive the body to the last inch of energy then go on! You gain nothing by just going up to where your body says you’re tired. The body will build and grow only to fit the demands the mind makes upon the lazy body. If all you do is exercise until the body is tired, the body will get lazy and stop a bit shorter every time. You must go to the point of exhaustion, then go on. That way the body figures out, “We’ve got to build up more strength if that crazy mind is going to drive this hard!” If you always quit when you are merely tired, you will never gain. Once you let the body tell the mind when to quit, you are whipped for sure. You can not gain by listening to the body. We can become much stronger if we drive the body. We use about one-tenth of the available strength of our bodies and less than that of our minds. - General George Patton
