How do u teach a driving rear leg

If back leg is the driver, then explain what Bryce Harper is doing here before contact?

How did Harper get onto/into his front leg?

Create this 'Torsion spring'

You fuse the upper body and arms into a unit by way of lower back and scap pull back. The hip coil pivots about the ball of the femur until it is tight and you end up with a torsion spring like stretch that runs from your leg to your scap.

Then you will know what it feels like to have the rear leg as the 'driver'.

Bobby,

You have to do things correctly off the backside to create what we see in the Harper picture. You can't just think you hit off the front side. or just off the backside for that manner. When I swing. correct backside action creates correct front side actions. Correct back side actions is getting the weight to the heel of the back foot and keeping it there for as long as possible as I arch the lower back creating leverage off the back foot. This creates hip snap/pop and violently straightens the front leg as a result of the hips popping. The front leg/hip snaps as a result, but is just as important as the back side.

Very very simple answer. The front leg is catching the weight. By this time all of the force has been created. THE SWING IS OVER

But he hasn't swung yet and his back leg is off the ground. The bat is still behind him. It looks like this is where the swing begins.

It looks like Pujols' leg doesn't move much at all before becoming unweighted and leaving the ground. And what muscles would he be using to generate all his power?

Where's the rear leg coil?

I don't understand. The rear hip snaps and violently straightens the front leg?

But if he stops at this point, would the umpire say he swung?
And then I see this. Griffey is clearly pulling his back leg off of the ground and into his body. Where's the power/driver? I'd think he'd be extending his leg if it was creating lots of power. They all sit on their back leg and then slowly shift their weight forward, often its nothing more than a controlled fall, and then back leg is along for the ride.
I just have a hard time agreeing with anyone who says the rear leg is the driver when I see Griffey and others forcefully extending their front leg to move the bat to the ball. Or I see the front leg collapsing when they take a pitch like Ruth does here... and note, his back leg is extended. What happened to the driver?

Whether you believe the rear leg is the driver or not, in a good swing the front leg straightening is a reaction to the force on the front foot created by the swing. It is not an action, e.g. they are not extending their front leg actively.

Then explain Ruth.... he's reacting to the force on the front foot but he's not extending his leg so it's not a reaction? Likewise, when I walk, I'm not actively extending my legs, they're just reacting to the force created by the prior step.... the foot striking the ground naturally causes the leg to straighten? Certainly you don't mean that?
