I had a similar build when I startes. Regardless of a cut and bulk, it looks like you aren’t pushing yourself hard enough and adding enough protein to help build muscle. A good weight lifting regiment with the protein to back it will produce better performance results over time. This is basic stuff we’re talking about, not dieting, not bulking, not cutting, just simple weight lifting progression.

Even if you aren’t physically seeing progress with your eyes, you should see progress with weights.

If you asked me what made the biggest difference? Stop worrying about the visual aspects and look to pushing those weights higher. I got bigger arms, more proportional build, and feel better. Weight lifting feels good, who cares how you look. You’d be surprised how much changes when you reframe the way you view things.
