The gif's below help show that the secret is in the toes. Look at how DD's toes bend and flex as she pushes off verses the rigidity of Ueno's.

Ueno's toes


DD's toes



Most us recognize good forward posture when we see high level athletes sprint, pitch, field, dribble, etc. We tell our athletes to lean forward and get on their toes, trying to get them over their toes, but for the most part it doesn't work... Why? Why is is so hard to do? It seems simple, but words don't seem to get it.

The lack of support in DD's toes effectively shortens her feet. The feet are already pretty small levers so shortening the effective zone (from the forefoot+toes to just the forefoot) has a pretty huge impact. This also affects center of gravity tremendously. Without support from the toes, it's all but impossible to get that excellent forward posture that we see in the best athletes.

I don't have the answers. Maybe its the traction in the front of our tennis shoes and cleats that allow our bodies to lose the usage of our toes without realizing it. Maybe if we played in barefeet or socks it would start to comeback... I don't know. I'm still looking for that magic training routine that would force a kid to use their toes the right way (it's easy to fake). I'm certain that it takes more than verbal ques and even conscious efforts to dig in with the toes (with shoes on). The one thing that I am certain of it that kids will never cross the threshold from mediocre to elite without finding it.

A good start would be for all of us to start looking harder at how our kids are using their toes.

There a ton of articles on this. There s one guy in particular and I'm almost positive this is where you are getting this info from. I cant remember his name , Can you share?

I have tried this in the past and its incredible how much different even walking with a locked in ankle is.

The locking of the ankle instantly activates the glutes. You can feel the glutes and feel how its freeing up your thighs. Its true!

This particular issue has been studied extensively in competitive weight lifting. Competitive weight lifting has as much to do with quickness as it does with strength.

Rather than reinventing the wheel for foot workouts:

https://drjohnrusin.com/advanced-strength-training-for-feet/

https://breakingmuscle.com/fitness/5-foot-strengthening-exercises-to-improve-speed-power-and-balance

I haven't checked out the articles yet, but I caution people to not associate strength with speed. Weight lifters are not inherently fast and in many cases are slow. In a foot race, I'd take a chunky lineman over a stacked lifter.

I know your post was in regard to the feet, but I will share an experience regarding strength. Early in our journey, I researched Brett Contreras who's stance appeared to be, get the glutes strong and they will take over and work right. From this, DD started doing a lot of lifting and reached a point where she should hip thrust and bent leg dead lift 205lbs for reps (all the weight in the house at the time). Her glutes got strong, but her running and pitching mechanics did not noticeably change.

Other research in the strength aspect reveals that many weight lifters struggle to develop their glutes. I believe this problem was part of what lead Brett to become "the glute guy" because his targeted workouts succeeded were raw weightlifting was failing. Leg/glute development from doing squats is totally different for quad vs glute dominant athletes. Another particular weak spot in lifting is calf development. It's so bad that many believe it to be purely a genetic attribute. My hypothesis is that there is a direct linkage to quad/glute dominant lifters.

Regarding converting quad dominant athletes to glute dominant athletes, IMO the wheel has not yet been invented.

I'd prefer not to put much time into the Amanda powerdrive clips as it adds too many variables to leg usage. I scoured the web for a game clip of her and couldn't find anything so if you can dig up a game clip, I'll check it out.

Here is a clip of Jennie's rear foot in action. To me, it seems like her foot kind of cams off of the rubber as opposed to driving through her toes. Maybe some see a slightly bit of toe push at the end, but I can't help noticing that her shin to foot angle after it turns doesn't show much extension of the joint.



Compare it to the leg drive of DD where she definitely driving through her toes, using plantar flexion as a power source.



The cam'ing pattern that I mention above is very common in athletic movements from pitching to the rear foot of a batter. It's seems to reflect a difference in the usage of the foot and lower leg. For low level athletes, they work the calf (and quad) muscles hard. For higher level athletes it seems more like a rigid lever where the assembly is simply transmitting force that has been generated elsewhere.

Low level...................................High level

To me, working the calves for propulsion is a slow movement and happens too late in the kinetic chain to be very effective. I don't know if it relates to wrist flicks in throwing, but it might be similar.

"K" to reverse "K" is much quicker and more powerful. It produces huge forward thrust that lifts the rigid foot/leg lever off of the rubber.
