An 8 strength charater isn't a weakling anyway.
They are someone who can walk all day wearing a pack, with enough supplies for two short rests at least plus maybe light-armour and weapons and spellbooks and potions (in glass bottles!) and loot. They can run, jump, and battle through fights.
Even wizards must be pretty buff from carrying spellbooks and a metal-shod wooden staff all day! And that's without material componants (I'd walk faster, but this guano is bat-shit-heavy!).
