Old guy-tonnage question

[Lost and Found]

I watched a couple of Rip's video shorts about old guys and tonnage, I want to make sure my understanding is correct.

I'm 71 yo. I usually do sets of triples for heavy work sets for squats except on a light day. Assuming the warm-up sets and reps are the same would Workout B provide equal or adequate stress with less tonnage than Workout A? Is that a sufficient reduction in tonnage or too much? Thanks

Workout A 300x3x3 (tonnage 2700)

Workout B 290x3, 300x2, 310x2 (tonnage 2090)

I think you need to explore the concept of Minimum Effective Dosage. At your age, and long-term, it will be a more useful approach to your training.

Thanks Rip

I take it this is a process of trial and error where the dosage of training pushes strength numbers but is still recoverable in a reasonable time frame.
