There are a few silly, and not so silly things you could have her do which might be fun to write:
1. Apparently there’s a current craze where people fill a backpack with heavy weights and walk long distances - might be fun to turn it on its head with a college girl or something carrying around a huge amount of books, or rock samples, or just heavy equipment.
2. It might be fun to have someone go up to a turnstile at a ticket office or something, and the bars are bent from someone absently mashing them out of the way when they go in.
3. There’s the classic lifting the couch one-handed to vacuum under it, but you could do the same thing with the fridge-freezer, heavy chest of drawers or even a car.
4. If there’s a nautical side to things, she could pull up an anchor without using the winch, or snap the chain trying to pull a set anchor off the sea bed.
5. Someone gets stuck in the subway train doors and she practically tears one in half to force it open for them.
6. When she’s hooking up the trailer, the turning wheel screw is broken, so she just lifts, drags and drops the tow bar onto the hitch with one arm.
All sorts of random ideas there… maybe they’ve sparked a few more thoughts from you!
