The actress sculpted a million-dollar body for her Oscar-winning role as a boxer in Million Dollar Baby (2004). The naturally slim Swank gained 19 pounds of muscle by boxing two hours daily and lifting weights six days a week. Her trainer even had her push an SUV in neutral gear across the parking lot to train her legs.
"My back, my arms, my legs - everything changed," Swank revealed on the Today show. After the movie wrapped, she cut back on weightlifting and returned to her svelte shape with a combo of Pilates and running.
