Your situation is not a complicated one, so stop trying to make it that way.
Do this for 3 months:
Diet:
-Don’t count cals or macros.
-Eat the bulk of your carbs just before and after your workouts.
-Try not to eat carbs with your first meal if you train after noon.
-While recomping, most of your meals should be a protein and a green veggie. But eat a healthy low fat carb with your meal if you want here and there.
Workout:
-Pick a tried and true program and actually work hard.
-Do something in between your work sets (pull-ups, light rear laterals, pull a parts, band work, stretch, move!).
-Do high intensity interval cardio twice per week on off days.
-Do some low intensity cardio on workout days if you can fit it in. If not, no big deal.
This is what I do when I want to lean up, and it has never failed me. I hover around 15%, and can get to 10% in a few months or less depending on how far I restrict carbs. It’s such an easy approach.
