I'm 6'5 and 235lb. Decently muscular after a year and a half of hard work. I really want to get into boxing but the only thing stopping me is weight loss. I don't want to do boxing and lose muscle mass since I like the hypertrophy.

Is it possible to balance both while gaining muscle mass NATURALLY? I don't want to jump on juice yet so it's not an option.

I barely eat as it is <3000 calories a day so doing boxing would mean I'll burn way more calories and lose muscle mass definitely.

Any advice is appreciated.
