Congrats on the weight loss/recomp. If it were me, I'd just continue to recomp whilst getting stronger, which of course, is a bit more difficult than starting out as a 135lb string bean at 19 years old. Your programming and dietary choices will need to be more precise to achieve these goals, but I think you're on the right track.
How often are you doing the push-pull split, just MWF or?
Diet wise:
As you know, this isn't really keto or low carb (in my book) but it seems to be working. What's your protein and fat looking like? How many days and for how long are you walking?Diet is basically keto, with about 150g carbs (75 either side of my workout) off days just some walking and less than 60g carbs.... This eating pattern was basically ad hocked together, going by my Blood Glucose meter.
