Wrong leggedness of the leap

As I have tried for about a year to get my kid using her legs better it has occurred to me that the fact that the leap is using the wrong leg must be a big reason why this is so hard. What I am talking about is how in other jumping activities the left leg is used (for a right hander)..

So is part of the difficulty in teaching the leap that it is like me trying to make a left handed layup?

I have always thought that both feet ought to be on the front of rubber the same....

but you are still striding with your left and "jumping" with your right...or vice versa....either way the drive foot is the opposite than that used for other one legged jumping activities.

and sprinting... see 1:10 mark (left foot forward)

Great point about the opposite foot being used. I don't know if this will help and I'm still trying to fully understand "drive mechanice" so be easy on me if I miss it or take a wrong turn. Java talks about both feet being a loaded lever in a sprinters position (please if I'm not exactly correct jump in). I was working on that with a student today and as I was demonstrating not letting the left heel sink in the sprinters position, I could feel an increase of load into the drive leg and hip from the stride leg. It felt more like both legs were loaded and in unison. This felt way different than the usual right , left, right bend and stride that a lot of girls do. I hope this helps somebody, Mike

I don't think you are off base at all, I do think this is one of the goals. I was actually attempting to have the rugrat do the "fall on the face" drill from a sprinters stance when it dawned on me that this is really hard to do. I got down to demonstrate and it felt so weird to take a sprinters stance with my right foot forward and it dawned on me that part of the drive mechanics training is teaching yourself how to use the off leg for power. It is not so much the load itself that felt weird but the firing sequence between rear foot to front foot. It just did not feel natural at all. When I switched feet everything felt perfectly natural again. This HAS to be a big issue in why teaching a good drive is difficult.

Before learning about drive mechanice, I would ask the pitchers that didn't seem to use their legs very forcefully, witch leg are you focusing on the drive leg or stride leg? They would often say the stride leg. I'd tell them to focus on the drive leg reassuring them that the stride leg would fire off and keep them from falling. It helped but using D.M. I can see a whole different level of using the legs because your using both. A lot of kids hold back, fear of falling, and never reach that sprinters position we are looking for. I also noticed I had better balance and contact with the ground doing it this way. Loading the stride foot without letting the heel touch the ground helps stability wise. It takes time playing with it and your calves will get sore. I also noticed my glutes got sore from being more explisove.

My dd is left handed but throws righty hits both, but her left leg is dominant. She's always tried to do all the striding without pushing just reaching with her stride leg. She joking told me she should switch to left handed so she can drive off the rubber better.

I've been trying to better my DM to help dd, the harder I try to push the worse it gets? It seems like if I'm just warming up not thinking about my weight shift and push my timing is pretty good even get some overlap, as soon as I start to think about it it sucks worse. I think there has to be a happy medium between really pushing hard and that quick explosiveness, idk if that makes sense? I've heard Tincher say it should feel somewhat effortless. When I'm really trying to push it feels anything but effortless!
