New Plan Advice

Hi all. Sorry in advance for the long post, but I don't have a fitness background and got good advice here in the past.

Background: 36y/o male. 5'10" 168lb. For the last 2 years or so, I have been training 3-4 days a week on a slightly modified GGP from Greg O'Gallagher. Below is my breakdown and related weights (as of today):

Day 1:

1. Seated DB shoulder press: warmup with 8x42.5lb. 3 set RPT. 6x70lb, 8x65lb, 10x60lb.
2. Weighted Pull ups: (5xbw warmup) 6x55lb, 7x35lb.
3. Weighted Dips: 10x70lb, 12x50lb.
4. Barbell curls : 2 sets RPT 8x90lb, 10x80lb.
5. Lateral raises: 15x20lb + 4x5 reps rest pause.
6. DB Shrugs: 8x70, 10x65, 12x60

Day 2:

1. Goblet squat: Warmup bodyweight x 8, light load 4/5. Working sets: 10x90lb, 12x80lb.
2. RDL: warmup barbell (8xbar, 6x105) 2 sets RPT 8x205lb, 10x185lb.
3. DB Bulgarian split squats: 2 sets RPT 8x55lb, 10x45lb.
4. Leg extension: 2 sets RPT 9x80lb, 11x70lb.
5. Weighted single leg calf raises: 2 sets RPT 10x35lb, 12x25lb

Day 3:

1. Incline DB press. warm up 8x40lb. 3 sets RPT 6x80lb, 8x75lb, 10x70lb.
2. Flat bench: 8x105 warmup. 2 sets RPT, 6x185, 10x165lb.
3. Tri push down: 2 sets RPT 7x95lb, and 10x80lb.
4. Hammer curls (superset with tri push down): 2 sets RPT, 7x50, 10x45.
5. Landmine press: 2x12 45lb. Third set to fail..
6. Bent over fly: 15x17.5lb, + 4x5 reps rest pause.

I finish every workout except leg day with a mile walk at 4.5mph, starting at 4 degree incline and increasing every minute to 10 and then back down. On Day 4, I either do some mobility stuff and run two miles, or walk 3.5 miles at 4.5mph at 5 degree incline.

I've had good success with all of the above, especially when I keep my diet dialed. I've gotten a lot stronger and am generally happy with my physique. That said, I'm pretty burnt out/plateauing and lately I've gotten interested in longevity, VO2 max, and overall functional health. My family has a long history of Alzheimer's/dementia/Parkinson's and I've read a lot about physical well-being preventing that.

So, I'm considering transitioning this to more functional athletic training and learning some kettlebell movements. I also want to maintain strength so am keeping a lot of the lifts that I feel like have helped me there. With that in mind, I'm considering re-working my program to something like the below, which is AI-generated based on my inputs.

Day 1:

1. Weighted Pull-ups (RPT. same weight as above).
2. Incline DB press (RPT. same weight as above)
3. KB Turkish get-up starting with 16kg.
4. Half kneeling landmine press at 3x8/side, starting with 45lb
5. Hammer curl/triceps pushdown superset (RPT. same weight as above)
6. Core circuit: L-Sit 3x20s, Neutral Grip Hanging Leg Raises 3x12, decline bench situps 3x12.

Day 2:

1. RDL (RPT. same weight as above)
2. Double KB front squat. 3x8 at 45lb
3. KB Swings. 5x10 starting at 24kg
4. Buglarian SS (RPT. same weight as above)
5. Single leg calf raise (same as above)

Day 3:

1. Flat bench (RPT. same as above)
2. KB clean to front rack carry, alternating arms. 4x6 + 20yd carry.
3. Farmer carry. 3x30yd heavy
4. Palloff press. 3x10 weight TBD
5. Landmine press (superset with Palloff). 3x10 weight TBD
6. AMRAP finisher: 6-8min: 10 goblet squats, 10 KB swings, 10 pushups with pull throughs.

Day 4:

Norwegian 4x4 on treadmill.

Day 5 (when I can):

4.5mph 3.5 mile incline walk at 5 degrees.

Also plan to add in mobility exercises in the morning 2-3x/week. Open books, thread the needles, seated T-spine rotations, wall slides, etc.

What do you guys think? Does it look good? Overcomplicated? Should I just stick to what I'm doing and add the NW 4x4 or some other VO2 situation into my existing program?
