Are these muscles?

Question

My friend sent me a photo of his wife at the grocery store buying some vegetables. Because he knows I like green food. But it made me wonder about something. I never noticed her arms were bigger than I thought. I'm just wondering if there muscles and I never knew she had them. Are these muscles or not. I couldn't tell. Maybe someone who can discern it can let me know. My friend doesn't know that sending this to me got me horny. Only because I had no idea she had these muscles. But maybe someone can tell me and confirm if these are really muscles or not. Look at photo
