Many new coaches and throwers struggle with fundamentals.
Fundamentals, when done correctly, make the process of learning throws technique easier.
Mastering the fundamentals is vital to implementing the throwing chain reaction of each discipline: discus, shot put, and glide shot.
… So what is this 1 error?
It’s understanding the Heel-Toe Position.
All too often the Heel-Toe position is an easy thing to let slide because it’s really pretty simple… when done correctly.
There is a “sweet spot” to the heel-toe, and that is why you MUST pay attention to it. It is easy for a thrower to be either too open, or too closed.
