What's Inside

This mini-course introduces the basics of biomechanics and how they relate to hitting. We use K-best to introduce common swing characteristics and bring measurables to swing mechanics.


  • We show how k-vest is set up correct
  • We dive into the graphs of k-vest
  • How to read the sequencing graph and what it tells you about your hitters swing
  • A dive into pelvis positioning and how the pelvis moves during the swing
  • Looking at posture in the upper body and how the graphs adjust during the swing
  • How to get the most out of x-factor, or the hip-shoulder separation of your hitters
  • The most common swing characteristics we've seen out of our hitters in our assessment and use of K-vest


Take your knowledge and understanding of the baseball swing to the next level.
