Brit babe Kate Beckinsale dominated the box office this weekend with the latest installment of her Underworld franchise, and if you caught a screening of the action-packed flick it was impossible not to notice her smokin’ hot body in that skintight catsuit!

SHAPE magazine has all the details about how Kate got her body ready for Underworld Awakening, straight from her trainer Ramona Braganza.

“For this movie, she was wearing a tight outfit so she wanted to look fit and curvy but not big,” Braganza says. “Because we’ve worked together before, I know she always likes workouts with yoga-inspired moves.”
