Evolution of the S2 Assessment

Posted on April 22, 2022 by Laura McDonald

One of my very first charges after starting at S2 Breakthrough was the development of an assessment to guide our coaches on how to approach training. We started with taking pieces of established approaches to athlete assessment that, on the surface level, seemed to match what we were seeking. Here’s what I presented at our Read More »

Posted on March 14, 2022 by S2 Breakthrough

I never set out to focus on data-driven softball player development. When Ashley and I formed S2 Breakthrough in 2012, the boldest thing about us was that we 1. were women! 2. took a seasonal focus and 3. offered strength and conditioning. But what drew (and continues to draw) me and Ashley together is our Read More »

Risk v Reward

Posted on February 17, 2020 by S2 Breakthrough

An elite softball player must demonstrate superior explosive power by producing force in a very short period of time (e.g. hitting, sprinting for a ball in the outfield). In order for force production to be efficient and maximized, the underlying movements must also be efficient.    We often use the term “elite mover” to describe an Read More »

It wasn’t until my freshman year in high school that my mom opted to send me to a strength coach for individual workouts, which encouraged me to embark down my path in player development. Ultimately, this is what sparked my passion for Read More »
