I'm 5'11", 230 pounds, been on a dirty bulk for around 2 years (yes, I know). I've gained 55 pounds during that period putting me at around 25%BF and a LBM of 172 lbs.

I want drop down my BF% to be as close to 10% like I was pre-bulk. During the last 2 years, a series of events happened that I only trained around half that time (a kid, injury and I'll admit it, laziness).

Right now this is my workout. What do I need to change? My greatest weakness right now is def my chest.

make your bench squat and deadlift your top priority and focus the rest around those

Would moving to something lift stronglifts be good? I did a it for a while, but i forget why I changed

I'm not familiar with that program but yes in general a proven program or style of training will promote better results than something you came up with on your own.

Working out more than 3x a week or at least doing more than 1x a week for each group would help tremendously. If you absolutely can only do 3 days a week its gotta be a full body regimen.

Also as Orakpo said, focus on the big 3 and do 5x5 for squat and bench (barbell preferred)

If you want to cut body fat why aren't you throwing in more cardio? what you are doing seems like a warmup for the body and would not have any other real benefit.

Also I wouldn't choose to do chest+arms on the same day but thats just me (also your arm day doesn't have any isolated tricep moves)

squats maybe once a week if has time

does 3 bicep exercises

seems like a good routine

but I have a whole day dedicated to legs?

nothing can replace squats brah, you're order of operation is all sorts of fucked up. Squat first, accessories after.
