I love that MC is a brock Lesner style freak with an hypertrophy; and the front back shot of the lift from triangle choke was fucking EXCELLENT.
I've actually done that lift in free sparing; it is absolutely possible within that weight range. But! I am short and THICK, which means that leverage was on my side; and I was significantly stronger than the dudes I've done it against; and they weren't trying to crank my elbow in half while I was doing it.
Against someone who trains seriously and is within a weight class or two of you AND is actively resisting, it is just this side of impossible; but it still happens: See the most famous example here

Basically, it's funny to me that one of the best martial arts manga I've ever read is this pervy garbage. 10/10 would read again.
