Thanks for the clarification on the usage of the VL. That makes a lot of sense, especially for what you are trying to challenge.
However, the exercise that I developed to address that aspect is (1) completely novel as far as I am aware and therefore more likely to draw scepticism, (2) the exercise is kinda dorky, and (3) to maximise the effect of the exercise in terms of appropriate strength to sprinting (designed with the use of inverse dynamics) I invented a shoe that is even more dorky especially in the prototype phase.
I’m pretty much open to hearing and trying anything once as long as there is a good reason for it, so I’d love to hear/try this if it is possible without the dorky shoes. Can you give a fair description online or is it something that needs to be seen?
