>>95909915 (OP)Lets stress test that
For 15 Your grown human shouldnt weigh too much over 80kg. Deadlifting 80 isnt that special but it depends on what lift means. Ohp 80kg is pretty special, but either case is enough for wooden doors given time
Above that is 25. A horse can weigh up to 500kg, we'll say 350 to be fair. Squatting 350 is getting close to a world record and ohp would be insane. If you're a world class powerlifter then yeah, a thin unmortared stone wall is not going to be too much of an issue even without tools
Now at 20, thats halfway between 80 and 350, so we'll say 200kg
If you can lift three people at once i reckon you can smash down a stone wall if you have any kind of tool available. Kids can knock bricks out of walls without too much trouble, so it checks out
