1912:Pat McDonald, USA, 15.34 meters
2008:Tomasz Majewski, Poland, 21.51 meters
Impressive speed improvements aside, the knowledge we've gained over the last 100 years about weight training and strength alone has obliterated what elite athletes in 1912 thought possible. The 1912 winning throw in shot put was just over 50 feet. Today, it's over 70 feet.
