By now, Harry had built up enough muscle and strength that he had little issue with wielding the Serpent Slayer replica and could train with it for hours before fatigue would settle in. He knew, deep down somewhere that such levels of fitness weren’t human, that no mere mortal could swing such a massive piece of iron for hours on end and be okay to keep moving later on. While sure, Harry had gotten much taller and more muscular, he was pretty sure he was nowhere near large or strong enough to do what he was doing. Heck, Harry was pretty sure not even those Muggle bodybuilders could do what he was doing.
