I suggest reading Barbell Prescription and Starting Strength. Barbell Prescription goes into depth on parts of SS for older guys and debunks the common misperception that light weight high reps are the way to go.I thought light weights more reps was what us middle age and older guys are supposed to do????
We have a few of them at my office but when you're 6'1 now you're towering over the people in adjacent cubicals which is kind of weird. If I was 5'6 that would be no issue.
I ran the Novice Linear Progression until I stalled, backed off 10% and ramped up until I stalled a couple of times (about 8 months of linear progress), then got on Barbell Medicine’s beginner program for about eight weeks. Their Beginner program has a mix of strength reps (4-6 reps) and Hypertrophy reps (6-10) and you’re trying to add weight. I’ve started their Hypertrophy program a couple of times. The Hypertrophy program is 12 weeks long, with the option to hang at the week 4 workload until you can bust through. I’ve stalled at week 4 a couple of times - in my case it’s related to recovery from higher reps (10-12) of squats and deadlifts. I can literally feel my CNS fry once I get past 8 reps of either squat or deadlift with the prescribed weights.
Both of the books I mentioned are good reads written by a crusty old fart from Texas.
