I'm a one-planer because before I applied any of this new stuff my arms and shoulders swing on the same plane and if I try to swing my arms up on a steeper plane than my shoulders they don't do it, my shouders just go steeper with em. So rather than try to change my natural swing plane it's easier to change my posture a little.

I was already standing quite far from the ball but I was standing more upright than he says for a 1P because I'm short and I needed to to keep the toe of the club on the ground. Since getting more bent over the toe is coming up a bit and I'm hooking the ball if anything so I need the lie flattening.

If you read the whole book he does give good scientific reasons for each thing he says. Being a bit of a scientist myself I think this dude has done his research and seems to be on the ball.
