[Harry Potter] Voldemort seems like a squishy Wizard. Why didn’t he use magic to give himself enhanced physical abilities?

Arrogance, and a different ideal self. Wizards don't have the same "Ideal self" as muggles, as their power comes from their magic, not muscles. They don't view physical strength or looks as important, only their magical power is judged.

Also, he never really needed physical power, none of the magic used against him would have been stopped by a six pack, so no need to waste the magic to amp his own physique.
