Probably just a push, pull and lower-body movement done circuit-style. Probably just shoot for a predetermined number of total reps and then continue circuits until reps amassed.
All movements predicated on: (1) lack of pain (2) can feel in muscle, not in joint and (3) can safely perform for higher reps. Sample movements might be: stability ball pushups, inverted rows, dumbbell step-ups, et.al.
Hoped for result: feel and move better, more muscle. This is an hypertrophy approach. Higher reps, higher volume, go for pump. Should be more fun in that I should be able to better quantify progress from week to week. May also throw in curls, side laterals, forearm work, neck work, etc.
Will try not to go hog-wild with the walking. Relaxed eating without aiming to 'bulk up.'
I'm pumped! or rather will be. Excited to have made peace with certain constraints, eager to get on with a more sensible strategy, one which should have me actually looking more like a fitness trainer. At present, notwithstanding my ability to move my body through space, I'm gaunt and wiry. Basically, I'm probably the tiniest I've been in my adult life. Chest is 38", waist 29", thighs 19", biceps 12". Obviously, the prior approach netted specific strength and agility but didn't do anything for muscle. Probably lost some.
