Now, just like if you are trying to make a car more powerful, you generally tweak the engine, if you're trying to make your golf swing more powerful, you're going to have to tweak the engine. And the engine in your golf swing is going to be your shoulders and your shoulder rotation. So making sure that you have a sufficient amount of shoulder rotation, but also making sure it's on the right plane and at the right speed. So as a golfer makes a backswing, we turn the shoulders back and we get a good full shoulder rotation. Now we can make a backswing with the hands and the arms. We can make a backswing with the legs as well, but that don't really provide a great deal of power for what we need in the downswing. The big engine for the backswing is going to be, this shoulder rotation and trying to create a nice big shoulder rotation. Not necessarily as much as possible because sometimes when you turn your shoulders as much as possible, other things within your swing break down, you got massive shoulder rotation but no stability down below.

So it's winding up the upper body and creating an amount of resistance with the lower body. Now, we've also got to make sure that we turn our shoulders as much as we physically can. So this isn't about you trying to swing up lie or like Jordan Spieth on the TV, it's about you tying to swing to the maximum that you can manage. So we can measure how much shoulder rotation you can get by how far around this handle gets. So you want as much shoulder rotation as you can manage. But you've also got to make sure that you maintain a good plane of shoulders, we don't want the shoulders to stand up and swing like this. So looking from this angle, correct shoulder rotational plane should be down, almost feel like the handle points down towards a golf ball and it definitely shouldn't be, this big shoulder rotation because I've lost my spine angle, I've lost all control of my downswing.

So a good shoulder rotation is the good engine of the golf swing, but it has to be on the right plane. We'd also like it to be balanced nicely against the good solid right side and a good solid right knee. So we turn back and we have a degree of resistance through the right knee. We certainly want to avoid it splaying out this way on to the little toe and I'd also like to see it avoiding locking out you know a small straightening of the knee is acceptable but I wouldn't really like to see it locked out, that generally puts too much body weight back into the heel and spins the right foot, so all the body weight goes onto the little toe, for a right handed golfer, that's the right foot. So we want the engine to turn back, we want to get a good shoulder rotation over a stable right side, we also want to make sure that we do that slowly enough to generate power. For a lot of golfers, if they do it too quickly and the swing is over in the blink of an eye, we'd generally consider that was probably too hands and armsy. So it actually takes quite a while to initiate shoulder turn and make a big full wind up. So you'd do everything slowly over a stable and resisting right side for the right handed golfer and make sure the shoulders turn on the correct plane. And that should start to initiate more power for your downswing by turning on the engine.
