I was hitting off the tee, focusing on my back foot being staked into the ground during my positive move and the scissoring happened. I didn't try it, it was not the point of the drill, it just happened.
You can see in the Trout gif above.. his back foot is anchored, his back leg gets long during his positive move, he scissors as a result.
Yup. Keeping the back foot down and the back knee ‘back’ should ER the back hip while the the mass takes out the remaining slack, which is how Trout transfers energy up the chain.
Head to toe stretch ... remaining in the back heel and maintaining that while the mass moves forward loads the hips while the upper has torqued and is primed to receive this energy. The hips remaining ‘closed’ until the slack is out is paramount.
Once the hips have ‘centered’ or ‘opened’ or have removed the slack, the core rotates against the hips stoppage.. or anchor affect.. some think the hips rotate.. but in reality, they get rotated...as well as the back leg and back foot... the lead arm goes through the same process in relation to the core and the hands to the lead arm and the bat to the hands.
The better one can take the slack out of the hips, the better the transfer up the chain. Effortless bat speed. A pretty good checkpoint imo is pelvic tilt. It’s the cores rotation pulling the pelvis up from a good force transfer.
I’m still working on my description of this. But it’s getting better.
