Almost 70 here. I now think mindset is everything in a lifting lifestyle. I’ve noticed a reduction in strength, but not intensity or energy. Though it sucks that 500 deads and 450 squats are behind me, I am reconciled to knowing the best I can do in gym is keep a good body and lift decent weights.
I noticed, today, a Marine looking guy spent 10 minutes stretching and wrapping everything he could wrap, and then he did squats with 315. I did same weight today but no wraps. Honestly, one would have expected him to have lifted at least 450 from all that preparation.
