Hello everyone. So for the past month I've started a new eating and exercise program for weight gain/mass gain. I've put on 10kg in the past month (67kg to 77kg) with excellent gains in muscle mass and really good strength increase. As a whole the bulking is going well, but my stomach isn't looking so great. I don't want to start with cardio because I fear that may compromise the entire point of the routine/diet. Any advice in terms of continuing to make cool gains, but reducing the distended belly look? I don't do any specific core exercise, I'm sticking to the meat and potatoes: bench press, deads, barbell work etc.
A bit about diet
For the first 3 weeks I was eating 3000cal a day + 2-3L of milk a day. Now I've cut out milk (sick of it), and am substituting it with natural yoghurt and increased complex carbs like brown rice etc. I'm not keeping much of an eye on saturated fat, my aim is to bulk up, and I suppose the cutting can come later. I'm just after some tips to help reduce the distention in the stomach, if possible.
