This is true. But, I wonder about these guys that travel around, go to different gyms, how can they really track it with various different machines, brands, etc and still grow?
I know for me I decided to start focusing on volume/intuition vs constantly tracking progressive overload because those key machines that I can progress on and find a mind muscle connection, they are never available when I need them. So I have to wait and end up 2 hours in the gym. The dip machine, any smith machine, preacher curl machine, etc. It made me hate going to the gym, 2 hours 7 sets
With volume and training just to go in and stimulate muscles and train intense, I never have to worry about that dip or shrug machine being taken, I can go in find what's available and get to work...more reps less time
This is my experience, I used to love beating the log book but over time I guess due to fitness trends my workouts become a battle to get that key machine more so than to add weight or reps.
