Nah that wasn't much, in fact that was a rather casual feat of strength for him, something he could "do all day". It'd be like holding a laundry basket over your head.
The biggest strength feat I can think of off the top of my head is when he deflected a comet that was large enough to destroy the world, or at least render it uninhabitable.
