So, this is a question on the rear hand (since this thread is about the rear hand and I don't want to clog up the forum making the new one) that doesn't directly apply to Frode, but it could be useful for him.
Does the right hand (or left, in my case, since I'm a southpaw) involve powerfully extending the rear hip? I've been looking at examples of triple extension, which involves extending the ankle, the knee, and the hip, preferably in that sequence, to maximise power output. Trying it in shadow (although I'm just a dilettante and a hobbyist) feels powerful, but I'm not currently at a gym due to health issues and I'm curious.
Because my flexibility and joints aren't great, when I do it, I feel a stretch in my hips when I try to throw the punch this way. As said, it feels powerful, but I'm only a dilettante and my approach is very analytical and based on logical suppositions and cross-referencing - I looked at hip extension in punching by looking at baseball pitching, actually. I'm aware that boxing is boxing and baseball is baseball, but I like looking at common movements between sports, especially ones that involve power generation.
@Reyesnuthugr your post on the first page was full of great advise, so I suppose that my question is directed at you, but anyone else who can help - a guy, if he sees it, for example, or Sano, etc, would be much appreciated.
