Joseph Hubertus Pilates (1883-1967) was a pioneering German physical trainer and the visionary creator of the globally practiced fitness system that now bears his name. Originally calling his method "Contrology," Pilates developed his unique system of mind-body conditioning during World War I to rehabilitate bedridden soldiers. His emphasis on core strength, breath control, and spinal alignment revolutionized modern physical therapy, dance conditioning, and holistic fitness.
