The Importance of Core Work in Speed Development

Jonas: Part of part of my job as an educator is to help coaches and athletes sometimes but mostly coaches understand the principles behind our speed and speed development. So I would say before we get into that this kind of defined core so, and it might just be semantics but I think it makes a lot more sense later on when we start talking about things like Trump discipline. Jonas: We first want to kind of work backwards so talking about linear speed and we can even break it down into acceleration. What are some of the things or some of the principles that need to remain constant for effective acceleration? And one of those things is going to be again what we call Trump discipline.
