Continued Toughness (3.5e Feat)
From D&D Wiki
Continued Toughness [General, Fighter]
You gain extra hit points at every level
Benefit: Whenever you would gain a hit die (at each level), you gain extra hit points equal to your Constitution modifier (minimum 1). These hit points do not apply to levels before you received this feat. Any effect that causes you to permanently lose a hit die also causes you to lose the extra hit points awarded by this feat.
Special: You may take this feat multiple times, each time granting an additional number of hit points per level
