“That somewhat depends on the location of those 300 pounds”
OK, let’s say that YOU weigh 160 lbs. Can YOU pick up 140 pounds and carry it around all day? What kind of muscle mass would YOU have to put on to carry that much weight? Fat people have to be strong to carry that mass around. Physics is physics. No, they may not be able to lift the same amount of external mass that you can, but their grasping strength is a different matter.
