It irks me when I see a groundy drags a couple of small limbs. At least, make the trip valuable. What's the point to move 160+lbs body to drag like 10 lbs of limbs.
But this guy is just stupid.
Optimizing the load is a desirable way but overloading that much is nonsense. Fatigue, short and long term wear and tear, dramatically increased risk of accident and downtime... He's seemingly a healthy young guy but he's wreaking is body and I bet that the chiropractor will be far from enough to solve the issues later, say after 50 y.o.
