Growing up my passion was playing baseball, actively playing from 5 yrs old through a American Legion baseball and town team program. In addition I had the opportunity to play fast and slow pitch softball which is a much different game. For 10 plus years I've helped coach in youth baseball programs. I was fortunately to be exposed to good instructional programs for youth coaches and learned much. Now with improved video and the internet there are more tools available to help make sense of how to take your game to the next level and help players better understand the purpose behind the skills you are teaching them.
One of the better video instructional series is by
IMG Baseball Academy which covers multiple sports through the YouTube website. What I liked is they have incorporated the "why and how" into the video series. They have used terminology that has become standard in learning the game of baseball and preform to a higher level.
Tru Mark in the near future will be using video clips to help expand the "understanding" of the different product offerings. For example, a video that answers why marking whisker plugs with the field line anchor and turf stake help with your field marking operations.
