History of the Diodatics Weights and System

Joseph Michael Diodati

Inventor of the Diodatics Weights



Story Of The Diodatics Invention

Diodatics Weight Training system was created by Ann Marie, to continue the legacy of her father, Joseph Michael Diodati, the inventor of the Diodatics Weights. He was born in 1929 in Sault Ste. Marie in Ontario, Canada and grew up as a skinny teenager who desired to have muscles and strength. He went to his doctor for advice and was told he would always be skinny.


Joseph did not accept his doctors advice and started to read every book possible about bodybuilding. He got a group of friends together and began weight training. In a few years, he opened Diodati's Health Studio for men.

Over the next 50 years, he built the largest health club in Canada, opened the first weight training gym for women and invented and patented the Diodatics Weights. He taught thousands of people how to effectively and efficiently weight train for bodybuilding, weight loss, and overall good health. Joe was responsible for building up some of the strongest men in Canada. Diodati's Health Studio held the powerlifting championship for seven consecutive years and produced several Canadian Champions.


In 1979, Joe opened the first weight training club exclusively for women, in Canada. He trained his daughters, Linda and Ann Marie how to effectively teach women weight training and they got amazing results.  The women not only sculpted and toned their bodies, they efficiently and effectively burned body fat from the weight training programs.

Joe proved that weight training was more effective for the body than doing strictly aerobics or cardio workouts. 

Joe had a dream one night and saw thousands of triangular shaped weights in a large warehouse. For years he was thinking of designing a new weight, but was unsure about the design of the weight, until he had the dream.

While the dream was still fresh in his mine, he got up and cut out a prototype. A few years later he won a US patent and manufactured thousands of Diodatics Weights.  

Ann Marie Diodati-Ybarreta, with 45 years of personal training experience, created the Diodatics Weight Training System, workouts designed for every body!
