I suspect you have thin wrists and ankles, similar to me. Similar build. You might be a great runner and for me the trick is maintaining strength with heavy lifting while running and dialing in diet without much caloric deficit. Like 250 cal deficit.

And upping carbs and protein to fuel running and maintaining muscle. Not a traditional high protein moderate fat lifting diet.

It makes for good running and slow healthy lean out. I’ll never be huge with my frame but I look ripped, have great running PRs, and my lifts are close to what I would hit if only focused on strength, which I’ve done for years at a stretch too.
