The picture above is of Serge Redding. He strict pressed 502lbs/228kg at the Olympics. Insanely strong guy.
As I gined weight I found this became more of a problem. When I was 175 I could sleep on my side on the floor and feel good, at 210 this became uncomfortable. The increased weight increases the pressure on all the bony points, and the increased muscle means less space for nerves and blood vessels if you lie on your arm.
