I thought that Thin Lizzy used to use 150LB in each hand for side laterals... with a 5 second pause at the top of each rep.
More like 15lbs😂
There’s no debate that you lose muscle with age. That’s why IMO the hypertrophy rep range is the way to go.
Tony Pearson and Bill Grant are good examples.
Your power lifter types almost invariably end up with numerous torn muscles and midsections wider than their shoulders.
