i see I’m about a week late to the party. But EyeDentist is correct. You are generally happy with your muscularity. You want more definition more than you want more muscle. You want to preserve the muscle you have.
Continuing to lift at a caloric deficit is essentially the only way to approach that goal, particularly when you want to get there ‘quickly.’ If you wanted to get there slowly, you could essentially ‘recomp’, which would be a fat loss/muscular gain process while not really changing bodyweight throughout the process. That would be slower, but could potentially allow you to gain muscle while stripping fat, instead of just preserving fat.
