"The Swoboda Physiological Treatment is the most condensed form of exercise obtainable. Without overtaxing the heart or nervous system, it produces greater physiological effect in ten minutes than is possible in two hours by any other." Collected letters of endorsement for this mail-order fitness system from the Viennese immigrant to New York, Alois P. Swoboda (1873-1938), the originator of Swoboda-ism and of Conscious Evolution--a system of physical and mental culture that dismissed the dumb-bell menace and instead employed isometrics; his ads by the nineteen-teens were staples of the popular magazines.
