All sounds good. You know it's the food that is the weak link & it sounds like you've committed to address that.
Carbs at night? Well ok, try it for 2 weeks - no sugar though.
Are you getting your oil in?
We're adding again to your work load.
Add in
barbell front squats to your breathing squat days.
Sets are 15,12 & 10.
These are technically difficult btw so take it slow.
After that add in
Leg Presses same rep range & make it heavy.
To your upper body hypertrophy day we're adding
Reverse Grip Bent over Rows. These too are technical - reps as above.
So i've got you at 2.7kg off winning. As discussed 1.5 - 2.0kg could be had with proper creatine supplementation.
Get the food nailed plus the new work load and it's all over.
You'all have fun with that now!
