In 1990 David’s appearance was of the average American male. He stood 5’10.5” and weighed 170 pounds. He had rounded shoulders, a weak back, poor digestion and circulation, inefficient elimination, aching knees, a potbelly, and double chin. Then he was introduced to a rebounder. He bought one and jumped every morning for a month and his whole body responded to the exercise. He noted that his belt needed tightening. Within six months people remarked about his more erect posture and increased musculature. He left like an athlete.
David’s change eventually impressed others who asked him to lecture a group of employees. He was invited to speak before Rotary Club meeting, Lions International, the Kiwanis International, and senior citizen centers. Three years later, David had become so popular he began to travel the United States the ten-minute Cellercise Program.
