As an older trainer, I have focussed more on recovery, as I choose to train heavy duty style, so it used to be,
Monday chest
Tuesday quads
Wednesday off
Thursday shoulders
Friday hams and calves
Saturday off
Sunday off
Monday back
Tuesday bis and tris
Wednesday off
Thursday repeat.
I have done this for 20 years, (I’m 63) and I had a physical job, but I quit concreting about 4 months ago and I have decided (after a few injuries, detached tricep tendon was one, and I did it at work ) that I am going back to the old push, legs, pull, I am going to train by feel, two days on, 3days on or whatever I can do until I feel I need a rest day. I’m also going to lighten the load, aim for 10 to 12 reps pulling up with one or two in the tank, instead of 6-8 with forced reps, drop sets and negatives.
If I don’t think I’m growing I’ll change it up again, a change is as good as a holiday.
