Johnnie O. Jackson knows how to work his upper body and is recognized for its definition with bodybuilders all over the world.
At 5’8”, Jackson weighs 255 pounds when he competes. While he has impressive 23” arms and a trim 32” waist, his 57” chest is by far his most noticeable feature.
When he won the Mr. Olympia competition in 2009, Jackson bench pressed 523 pounds and deadlifted 815 pounds. In 2012, when he was 40 years old, he managed to deadlift 832 pounds, which was his personal best.
His gym routine consists of exercises like incline barbell press, bench press, decline barbell press, weighted dips, and cable flys to keep his chest big. He eats about seven or eight meals a day to keep his body fueled enough to power his time in the gym.
The amount bodybuilders have to eat to maintain their mass should be considered a sport in and of itself.
