I wouldn't say load against the ground necessarily although that is on way to do it.. The reason some of us speak of compressing/loading within the s-plane is it removes any chance or fear of lunging (shifting across the pelvis to the front leg).. If one starts 60/40 they land 60/40 dynamically balanced, all because UFA's occurring within the s-plane.So y’all see a load into the ground resulting in the front heel coming off the ground. I see it as the front heel coming up creating the gather. If you read this board everyone teaches some kind of gather. I have too. My experience is that teaching a gather can get you in the weeds quickly and create timing issues. I know slow and early. For the dads on this board that have timing issues I’m offering a slightly different solution. The gather and the front heel coming up happen simultaneously for many of the best hitters and I’ve had success teaching it. If you can get them to gather and go and be on time, that’s great. If they are late try what I suggest and see if it helps.
Not saying its easy but it puts hitters in the best possible position when leveraged.
