Historical European Martial Arts. At least for rapier and sabre, many people start late in the 30s and can compete pretty well internationally (see https://hemaratings.com/ https://hemaratings.com/) Same with sword and buckler, Though I believe longsword and armored fighting needs more athleticism than other arts. Feel free to see if you have a club nearby.
