You have to deduce a person's real feelings about a thing by a smile she does not know is on her face, by the way bitterness tightens muscles at a mouth's corner, or the way air is allowed to flow from the lungs.
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.
The breaking wave and the muscle as it contracts obey the same law. Delicate line gathers the body's total strength in a bold balance. Shall my soul meet so severe a curve, journeying on its way to form?
Doing is very good, but that comes from thinking. Little manifestations of energy through the muscles are called work. But where there is no thought, there will be no work. Fill the brain, therefore, with high thoughts, highest ideals, place them day and night before you, and out of that will come great work.
I cannot draw a human figure if I don't know the order of his bones, muscles or tendons. Same is that I cannot draw a human face if I don't know what's going on his mind and heart. In order to paint life one must understand not only anatomy, but what people feel and think about the world they live in. The painter who knows his own craft and nothing else will turn out to be a very superficial artist.
The athlete who is building muscles though weight training should be very sure to work adequately on speed and flexibility at the same time. In combat, without the prior attributes, a strong man will be like the bull with its colossal strength futilely pursuing the matador or like a low-geared truck chasing a rabbit.
