Van-sensei was kind enough to let me into his private torture chamber last week. For those of you who haven't experienced this thrill I would advise that you get a medical checkup before requesting an invitation!
Despite some personal frustations (e.g. locked keys in car while with harried wife)in just under an hour, Van was able to impart additional explosiveness into some of my techniques.
Van, please accept my deepest thanks for your time and my humblest aplogies for any incovenience.
