If you guys are talking about original fable, the best way to train physical is with the sword of Aeons* (solus greatsword** if you dont have it yet), if your talking TLC use either the solus greatsword with XP augmentation, or the bereaver*** (weaker then the solus greatsword, but with loads more augmentation slots) stocked up with XP augmentations.
The two best places to farm are cliffside path near bargate prison, and outside greyhouse... greyhouse is easyer to get at but there are infinate undead at the cliffside path.
Depending on what your training youl need somthing different.
Training physical? Bring red meat (or ages of might potion)
Training Skill? Bring Carrots (or ages of Skill potion)
Training Will? Use lightening**** on the smaller undead untill more respawn (or are summoned by undead lords)
Rapidly use Summon (or if you dont mind being fat, or are low on manna potions, fish and ages of Will potion)
Do not use Ages of ----- potions, food or summon unless your combat multiplyer is like, above 28.
**Solus Greatsword can be bought in bowerstone north, or given to you by Lady grey as a gift if you marry her. it is the strongest weapon in TLC and second strongest in the first.
***The Bereaver is acheaved only in TLC by giving all your silver keys to the demon door in nechropolis (HIGHLY RECOMENDED THAT YOU HAVE OPENED ALL KEY CHESTS FIRST)
****You can speed up your damage and combat multiplyer with lightening by rapidly changing targets wilst casting (not sure if it alters how fast will is drained)
