This is from one of Pavel Tsatsouline's emails that I'm signed up to and is a sample of the kind of information available from a monthly pay newsletter he also offers-
“Throwing a shot (7.25kg or 16 lbs.) is especially effective [for strikers],” states accomplished Russian fighter and coach N. Vasiliev. “One must throw at least 10-12m (33-39 feet). Experience shows that reaching this standard predicts a knock-out punch with a high degree of reliability” The shot weighs as much as a human head and effectively “builds” the punch.”
If only I'd known this a few years ago! My brother used to serve with the Paras and some of the guys he knew in the Regiment were seriously into their weights. He'd asked once about what their goals were and more than one replied that they wanted to be strong enough to punch a guy out with one blow.
And all they had to do was practice throwing a shot put!
