@nowhereman I’m the same age, but I’ve been training for hypertrophy for yonks
12 reps at 50% for warmup, then 10 reps at 60-70, 8 at 70, 6 at 80% and if there’s anything left in the tank - 4 at whatever I can manage. Increase reps by one every time you cycle that routine. Increase weight then reset the reps every 4-5 weeks
Gains are so slow, but endurance is great. I’ve started booking a trainer once a week for form check and routine update
Don’t forget cardio and legs. I still try and do a trail run or outdoor run once or twice a week, but if I’ve over stressed the legs, then I will just do a couple of assault bike or treadmill sessions to keep the heart rate up at high levels.
… but the sucky part is ditching beer 4-5 days a week, sugary drinks pretty much ever, and watching the macros.
