Keep an honest food log (fit day and calorie king are good resources) and calculate your maintenance level for caloric intake.
Figure out how much you gotta eat, and use your BJJ/metcon/complex days as your base and then eat 500 or so calories more per day. If you're not leaning out, reduce your carbs and make them come from fibrous sources.
Try this out and report back. There are a bunch of people that have contributed to your threads that are far more knowledgeable than I, but everyone can pitch in a bit and help you with your goal.
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
