As well as at twenty. Only avoiding maximum loads on lower back and knee joints.Rest between workouts up to two or three days. However, everything is individual. I will only say that the primary priority (in my opinion), with age, should be the desire to maintain quality. Control of nutrition is probably even more important, with age than in young years.
Individual approach in each case, the fundamental principle.
I rarely max out anymore. Isn't worth it...ego vs chance of injury. Wasn't easy to do as I'm lbs for lbs one of the strongest guys in the gym.
I used to work around the 5 rep range. Now it's more in the 8-12, except legs, I go pass 20. Use machines that you put weights on more than I used to. May restrict movement and not engage supporting muscles as much...but a LOT less chance of injury if you are going higher in weights with no spotter.
Do more HITT. I hate doing $hit like burpees but part of the conditioning. Seldom bulk anymore...my weight stays within 3-4 lbs all year long. Don't do orals much anymore because I like to drink a beer a couple times a week.
Donate blood every two months. Talk fish oil. Cut carbs way down...so no breads, potatoes, or pasta...but I love wheat beer. Other than beer, everything I drink has no calories. Eat mostly chicken, fish and vegs.
Date younger women..much younger...like half my age minus 5 (but legal). Keeps you young...they love sex with someone that knows what they are doing.
On the course I train 4-5 times a week, in breaks 2-3 times per week. Exercises like the body of each individual ... so if you follow the technique, you can perform any exercises, you need to feel the working muscle and try to unload the joints, and age is not an obstacle, the main thing is listen to your body.
me too brotha, mon,wed,fri, I never max out any longer, but occasionally go down to the 3-5 rep range but not often, instead of focusing so much on weight I utilize drop sets and partials at the end of partials I will get my partner to apply pressure on the eccentric portion of the lift ( that depends on movement ).
