As long as Hill stays at 155, there will be a HUGE risk of injury for him. Instead of coming back at 155, he needs to take another year off and powerlift 5 or 6 times a week and comeback at 170 at least. Regardless what Rogan said when Hill fought in the UFC, Hill isn't healthy at 155. He may be in shape, but he is too thin. Look at it this way, he broke his leg by landing a leg kick. What if Tyson Griffin, or any Muay Thai based fighter, landed a leg kick on him? For his own sakes, he needs to do nothing but powerlift for awhile and put on at least 15, 20 pounds of muscle.
