I do like 5 working sets and usually 2-3 warmup sets I don’t even count per exercise but you are 80 years old so good job
You have no clue what a working set is asshole and most people I know don`t count their warmup sets either......what a concept!
When was the last time you did Skullcrushers,French Presses,Squats (legit depth for reps without a mis-count),Hack Squats,Leg Press, any type of pressing exercise for shoulders,any type of rowing exercise that didn`t involve using a cable,Deadlifts,heavy Shrugs,etc. etc.
I`ll wait!
