Peter Rasmussen has released a couple of new training videos. The jump smash is covered again, as well as the cross court net shot. You have to sign up your email address to see them, but they're really good explanations: http://badmintonlife.com/newsletterbc/
Good stuff indeed just bought the DVD and access to the related online material. Peter clearly demonstrates a number of learning points which I will surely try during my next training sessions. Happy badmintoning
