Interesting...so what did you like? Seems to me one of his main points was at 4mins and very wrong...as he says to focus on torquing the racket around into contact.
I do like what he said about learning it right from the start and letting go.
I don't know. It does seem a bit off, but it just brought a better awareness that when it comes down to it, the contact area is the most critical part of the stroke. And when I compared it to my backhand, I didn't have as much of that quick action around contact, like the energy was dissipated before it. That realization and subsequent adjustment brought instant improvement, without even practicing it on court. When I got on court, my forehand was just ON.
