I love how the pros lift in the mag photo shoots with lighter weights (for their size and strength) and make people think you can get as big as them by lifting lighter weight. Most of them got huge by lifting heavy ass weight and doing more powerlifting style routines in their early days.
Most of the biggest guys out there got that big by lifting a lot of heavy ass weight. Ronnie, Johnnie Jackson, Dave Henry, and the list goes on and on. Guys see them lifting lighter weight after they already have 23" arms, 34" thighs and a 55" chest and think that's how they did it.
If you get huge lifting light weights, congratulations on having great genetics. You should get on stage!
