Not really. Unless you mean mentally.
Batman has a suit of body armour and an arsenal of weapons.
If you had those you'd only need to be mentally prepared to almost/possibly kill someone, rather than be physically hard.
That's absolute rubbish. It's not just down to the equipment.
You couldn't put some 30 stone, 50 year old couch potato in that equipment and expect the same results as if you put LeBron James in it.
James can jump really high, and he's got stamina, or that Anth Middleton the SAS bloke.
Some 30 stone JustEat Junkie would get smacked all over the place then set on fire. All the gear and no idea.
