Machine based program

Cut, gain, or maintain?

Cut probably, but maintain as much as I can. I don’t have a problem with getting adequate protein

You seem really set on machines. Does it have to be machines, or do you just need a step away from what you've been doing in PPSA?

How far do you feel you need to diverge from PPSA programs?

Why not just swap exercises out, machine pressing in place of bench pressing, for example. Keep the sets and reps the same, but drop all the super-setting completely.

Adopt more calisthenics and gymnastics. If you want, your entire workout can be built around calisthenics and gymnastics moves. Warning: if you don't know what you're doing you can mash yourself up just as easy with that kind of stuff as you can with heavy barbells.

Cook up some conditioning or endurance based goals and focus on that for a set period(4-8 weeks). Over a year ago I bought a rucksack and started rucking, and that opened up my eyes to all these rucksack/sandbag based circuit workouts/metcons. That stuff was a great change of pace from barbell /dumbbell based lifting.

Just some ideas, I think you can brew up yer own program if you think about it enough. Good luck.

I’m not dead set on machines necessarily, but thinking that it could give some of my joints a break (perhaps) from doing heavy (for me) compound lifts for the last couple of years. I figure the machine lifts are going to be more isolated to muscle groups than some of the barbell lifts are. And in turn, maybe that will be easier on the joints.

Adding in some real flexibility and core strengthening sessions would help too.
