Strength training question?

I'm the worlds slowest work-outer, so I don't do full body or I'd spend 5 hours at the gym every time.

If I warm up for 15 minutes, split my workout up by muscle group, and spend 25 minutes on cardio afterward, I can get it all day in an hour and a half, 4xs a week.

I do legs and glutes, arms and shoulders, abs and back, and some sort of torture with my trainer. Lately it's been an obscene amount of chest work since she's figured out that I avoid it like the plague. It works for me because it keep me way less overwhelmed.

You can do full body in 45 minutes or less.

Day A:

Squat
Deadlift
Bench Press

Day B:

Squat
Pendlay Row
Overhead press.

Three days a week, alternate A-B. And Voila, whole body worked in the most efficient way possible.

Boom....beat me to it. Full body is the exact opposite of time consuming isolation, assistance work. These lifts should be at the core of any lifting regimen.

I understand that. I'm not doing isolation for the most part.

Last week looked like this:
Day 1: Jumping Lunges, Mountain climbers, box squats w/barbell, jump squat w/barbell, and weighted lunges

Day 2: Military press, lateral raise, front raise, push ups, bench press, rear delt raise, arc press

Day 3: Planks, glute bridges, cable kick backs, calf raises, incline sit-ups.

Day 4: Good Mornings, that thing where you sort of lie down and pull the bar toward you? T-bar something? No clue what it's called...etc.

So. I'm not sitting around doing bicep curls on a machine. I'm just trying to figure out the benefit of working literally every single muscle in one day. Is it faster results? Fewer things to worry about?

I'm just here to make up the numbers for ironanimals side. It must be bromance!

Only once you spot my squat.

Day 2 has got to be brutal on your shoulders. I'd look at changing things up. I would focus on upper and lower alternating each day. Day 1 - OHP, Day 2 - Deadlifts, Day 3 - Bench Press, Day 4 - Squats. You can add additional exercises on those days that compliment the areas being worked as well as the antagonist muscles (opposite side) that need to be balanced.

It is brutal. And today my knee that "clicks" when I walk decided Day 1 is too hard on my joints as well. Definitely going to take y'all's suggestions and change it up a bit. I gotta say I'm getting some amazing results, but it isn't worth joint damage.
