How does a low Strength stat translate into the narrative?

I’m having trouble with something. In a ADnD 2e campaign how should a low Strength translate into the narrative/roleplay of the campaign? It’s easy to figure out how high Strength would work when narrating or roleplaying, but I can’t quite figure out low Strength scores. I like to narrate what’s happening like a story with as much detail as I can to really paint a picture for the players. This is throwing a wrench into that.

For example, characters can end up with an effective Strength of 5 if they get hit by a ray of enfeeblement spell. Though the spell says what this means for game mechanics it states "Your DM will determine any other effects appropriate to the affected creature." and I’ve got no idea what sort of effects it may have. I know, according to the Player’s Handbook, that a Strength of 5 offers only a ten pound weight allowance with a twenty-five pounds Maximum Press so a fighter would likely end up dropping their weapon and shield but what about the armour they’re wearing or the other stuff they may be carrying? They can’t just drop that stuff so, what, can they just not move or something? What would a character with a Strength of 5 be capable of? How should a DM or Player portray such a character?

What would a character with a Strength of 1 be capable of? From a narrative stand-point, not just a mechanical one.
