I know what you're body will pretty much look like.
I'm 2 inches smaller than you and weight 2.5kg more despite being injured for around 5 months.
You will have to suck it up.
I can understand what you are saying mate but if you don't track calories then you'll either not be in a surplus or you'll be bulking by too much. You need tp track ideally (but i can see how that can become a bit 'much'
It is your aversion to getting into a surplus that is stopping you.
If you bulk slowly, if you gain 14lbs, at least 7 should be muscle. Perhaps 9/10 as you're new to training.
That means that although your abs will go mushy, you'll look better not worse.
It is just something you have to do.
Do you want to be the guy on the left or the right on that bottom picture (ignoring the height difference)?
It is obvious we want to be the guy on the right.
I highly doubt you look like the first photo.
2nd one, guy on the left. Yeah, maybe with a pump.
There is no need to be lean in late autumn, winter and early spring.
