Boykins has short arms, that's why he can bench so much. Very small range of motion.
Yup. You can't emphasize how much of a difference short arms make when it comes to benching.
I've never understood this theory. Yes it's a small range of motion but the other guys have arms and chests probably three times the size of him. Doesn't that even out?
It's simple physics. He gets more leverage. The chest is the muscle doing most of the work and the further away the force is from the chest, the more torque the chest will endure. The shorter the moment arm (in this case his arms), the less torque on the body.
Think of a wrench. The longer the wrench handle is, the more force you can put on the bolt with less turning force at the hand.
Edit: The wrench example confuses the point sorry. The bolt is the chest muscle. The longer the wrench handle, the more torque you put on the bolt with the same amount of force turning the wrench. So...same weight on the bench press, more torque on the chest with longer arms.
