This is a very interesting video about the 1963 San Diego Chargers, and how they were basically required to take Dianabol (anabolic steroid) as part of their training program. No one knew what it was. No one asked questions. No one thought it could possibly be harmful. But, it worked. There also a short segment about how strength training was introduced into pro football after a military man observed what was going on in Europe. His mission was to debunk the myth that lifting weights would harm athletic performance.
