No, I understand your point: it's just that had you been around more gyms you would realze that, sadly, this is an extraordinarily common body type amongst the species Gymus Rattus.
A key rule in life is that 90% of everything is shit. This includes trainers. For 90% of them, training legs beyond the occasional set of half-range leg presses just doesn't exist.
Because their knees hurt. or they fucked up their back. Or their hip. Everyone of them has some bullshit excuse why they don't squat and they're all just that: bullshit.
People don't train their legs because it's hard. It hurts while you're doing it and it hurts the next day and (if you did them right) it hurts the day after that. So most people say, "Well, you can't see my legs anyway," to rationalize the fact that they're pussies.
Take pride in this fact; stare at the lightbulbs next time you've got the bar on your shoulders and be glad you're not one of them.
