And they guy looked amazing in his 70's. He competed well into his early 60's if I'm not mistaken. I also believe he was an olympic weightlifter for a small time. I know Sergio lifted for his country in Olympic Weightlifting and many other IFBB Pros back in the day also Oly lifted like like Arnold, Bill Pearl, etc.
Those are some nice peaks...IMO thats mostly genetics you see some horror shows at the amateur level of today with synthol and other site enhancement oils...but back then that was genetics and hard work in the gym
Albert Beckles was amazing, I used to see him everyday when I trained at the Northridge Golds Gym when I was in my late teens......him, Victor Richards, Luis Freitaz and tons of top NPC dudes at the time!! I remember asking AB if after he finished working out if I could ask him a few questions and his number one thing for gaining muscle (one of the questions I asked him) EAT A LOT and SLEEP!!
