A weight machine is an exercise machine used for weight training that uses gravity as the primary source of resistance and a combination of simple machines to convey that resistance to the person using the machine. Each of the simple machines (pulley, lever, wheel, incline) changes the mechanical advantage of the overall machine relative to the weight.

Famous quotes containing the words weight and/or machine:
“I, being born a woman and distressed
By all the needs and notions of my kind,
Am urged by your propinquity to find
Your person fair, and feel a certain zest
To bear your body’s weight upon my breast:”
—Edna St. Vincent Millay (1892–1950)
“The cycle of the machine is now coming to an end. Man has learned much in the hard discipline and the shrewd, unflinching grasp of practical possibilities that the machine has provided in the last three centuries: but we can no more continue to live in the world of the machine than we could live successfully on the barren surface of the moon.”
—Lewis Mumford (1895–1990)
