Deanna Jones-Guinasso was a pioneer in the sport of women’s bodybuilding. In 1977 she helped organize the first bodybuilding competition in northern California to include women. When females began using steroids, Ms. Guinasso shifted her focus placing 7th in the Ms. National Fitness, where the other competitors were half her age.
She participated in a number of athletic activities throughout her fitness career including running marathons and 100-mile roller-skating events. Ms. Guinasso is a long-time student of anatomy, physiology, and kinesiology. In 1992 she invented an exercise device (patent #5,399,138), the ButtMaster®, marketed by Suzanne Somers.
At sixty she was involved in the equine sport of endurance racing and competed in the Tevis, a one-day 100-mile race from Squaw Valley down to Auburn. At 73, she spends her days working out, gardening, painting, and writing.
