I'm just eating to eat. I eat relatively healthy, but Im not counting calories. I ramp up on days I train hard and low carb the days I don't. I don't do much running, mainly technique work and boxing conditioning.
I do 20-30 reps till failure 5 sets per exercise, 3 to 4 exercises a muscle group. i don't train arms and haven't for 2 years/
Ultimately I just wanna be a pretty good journeyman. I have talent but started late. I make more money now than I would likely make if i never took a loss for at least 15 straight fights over 3-4 years. I say all that to say if there were hundreds of thousands or millions of dollars on the line I would do whatever is necessary to be the best regarding the appearance of my physique, but given the reality of my career i would like to keep a little muscle even if it means it requires more oxygen
