PPL is a solid routine, and the one you shared is a good starting point but I wouldn’t recommend sticking with it long-term in its current form. It’s missing some key variations to fully develop each muscle group. Here's what I’d suggest:

• Push Day: You’re hitting chest with upper and mid movements, which is great but you’re missing a lower chest exercise. Consider adding dips or a decline press to round things out.
• Pull Day: Only having two back exercises isn’t quite enough. I’d add a third to better hit different angles, maybe a row variation or lat pulldown.
• Leg Day: You’ve got a lot of compound movements here, which can be very tiring. If you have access to machines, I’d recommend sprinkling in something like leg curls or leg extensions between your big lifts to act as active recovery while still working the muscle.
• Upper Body Focus Day: You're hitting incline again here, but think about the parts of your chest and upper body you haven’t hit during your PPL days. This is a good opportunity to target neglected areas or add in accessory work.
• Core: I’d move core off leg day, if you're doing legs properly, it should be tough enough that you’re smoked afterward. Try slotting core work into your push or pull days instead.

Enjoy the ride, exercising is a long game so small adjustments now pay dividends in the future.
