Leroy Colbert

Colbert famously was wary of the worth of using steroids and never used the substance in an era where steroids had just started coming into bodybuilding. His views on steroids were formed in his later years as he was unaware of their effects in his youth and admits he would have used them had he not had his accident, stopping his competitive career. He started training age 10. In 2003 he was inducted into The IFBB Hall of Fame. He was the first black man on the cover of Muscle Power magazine.

All the measurements are from Muscle Power magazine (November 1953) before his accident, apart from arms which he developed to 21.25" after his accident (once his competitive career ended)

Leroy Colbert (born May 9, 1933 NY, USA - died November 20, 2015 age 82) was an American bodybuilder. He is notable as being credited as the first man to develop 21" circumference arms. He was a traditionalist using full body workouts with a mini push/pull, where you a pushing exercises following by a pulling exercise. This also applied to legs don't do a quadricep exercise followed by another quadricep exercise. Leroy said you are not giving the muscle enough rest when you train it back to back. He and along with his friends such as Marvin Eder in their youth pioneered many of the principles bodybuilders today use. An example of these principles were the 21 curls where you do 7 curls to perpendicular, 7 curls perpidicular to chest and 7 full curls. Another example of Leroy's principle was the priority principle, where the muscle you train first will grow biggest because you put the most energy in the beginning of the workout. It was also to be paired with the saturation principle where the first exercise you do the most sets to saturate it with blood. Lastly, Leroy and his friends also pioneered the tri and quadra sets in a Bicep,Tricep,Bicep....etc. style. His other training principles can be found on his channel.
