By the time Rocky Balboa reached the top of those museum steps, the world knew it had a fitness icon in Sylvester Stallone.
That was 1976, and yet the Italian Stallion is still punching, still lifting, and somehow still in ripped-to-hell Rambo shape at 71 years old. Whether you're fighting a seven-foot Russian machine or just the sands of time, it is — to quote a boxer from the slums of Philadelphia — not about how hard you hit, it's about how hard you can get hit and keep moving forward.
