The art of the javelin throw with Dr Klaus Bartonietz

You may know him as Neeraj Chopra's coach. But Dr Bartonietz or "Dr Javelin" is one of the world's leading experts on throws, and has been conducting research and analysis on it since 1975. Now, as Neeraj Chopra gets ready to throw competitively again a year after his Tokyo Gold--he will be participating in the Paavo Nurmi Games in Finland on June 14--Dr Bartonietz breaks down the technical complexities of the javelin throw and why Neeraj is ready to breach the 90m mark. From release momentum to the biomechanics of braking, from release angles to the role of the shoulder, learn why just being big and muscular doesn't mean you will throw longer distances.
