You see, the body ain't no piece of CGI. It's a living prop you gotta treat with respect. A stunt double that can lift a 200‑lb wrecking ball and still land on their toes is like having a spare set of hands on set. Training turns muscle memory into reflex, so when the boom explodes the body is already set to absorb the shock, not just hope the cameras capture it. Think of it like a good shot – if your frame isn't tight, you can't fix it with a filter later. So yeah, a well‑conditioned performer is half the stunt, the other half is that proper rigging you never trust an extra to set up. No fancy gadgets, just solid bodies and a good dose of duct tape.
