lack of muscle tone

I remember some time ago, while working in PSA building, I used to attend dozens of meetings a day.  In a boring meeting, when you look down on the meeting table, all you see are your co-worker's forearms.  I used to be very troubled by undefined forarm muscles in my male co-workers.

And then I moved to Taiwan and it's either mostly surrounded by women or fewer meetings or both...  But today, I got a flash of flesh - undeveloped flesh to be specific.  It is awful.  I couldn't stop staring.  I couldn't focus on the words coming out of his mouth.  Even Matty has more muscle tone.  Very troubling.
