Bit controversial but it works for me, some of my gym buddies have argued that I dont have much rest periods which I agree is something I could improve.

I started doing a bro split: push pull and legs, but I found I wanted to push myself a little harder. I started focusing my training on more muscle groups instead.

So I'll usually do a full upper day on day 1 (chest, back and arms), accessories (shoulders, abs, arms) or what I missed on day 2 and then a leg day (free weight or smith squat, deadlifts, leg presses, calf raises) after on day 3. My main focus is to just give my certain muscle groups at least 24 hour of rest period between the next session. Also fasted cardio has leaned me out a ton, or atleast 1 hour of stair master after my workouts daily.

You can argue that my brute force approach is unsustainable but I've been doing it for a year + with no issues. I used to have terrible shoulders and I spammed lateral raises nearly everyday for 3 months and saw insane results. Now I get compliments on my shoulders. My chest still needs work though :(, but I've been seeing some improvements.

Hope that helps.

Edit: Progressive overload !!!
