The difference between knowing the problem and fixing the problem is what seperates great coaches from average ones. This is the art of coaching. I love reading about how master coaches approach this topic and have written several times about finding the right cue and when to change it.
The process is not always easy. For example sometimes to get the feet to do one thing, you have to focus on an entirely different part of the body. This is where knowing the athlete, knowing how they learn, and how they move are of utmost importance.
But you can also easily overthink this process. I had this experience last week. One of my throwers was coming off of a break and consistently starting double support very late on the first turn. Naturally this problem snowballed into larger problems later in the throw. By the final turn she could barely get the hammer out of the cage. While landing late was a major problem, the issues had already started with errors in the winds and entry. So to fix it we focused on letting the ball run more on the entry, thus giving her more time and the proper balance to land earlier.
In theory this approach was great: we traced the problem back to its root cause and attacked it there. The only trouble was that it wasn’t working with her. Throw after throw were showing the same problem repeating itself with only minor improvement.
Finally I explained again the goal of this cue: we wanted to land earlier and by creating a longer path for the hammer on the left we give the body time to do just that. She stepped in the ring for the next throw, caught the hammer early on the first turn and produced her best throw of the day. I asked her what clicked and she responded “I just tried to land earlier.”
With some athletes and some issues you need to break things down a lot. But with others the simple path works just fine. Sometimes they need to just do it. Don’t forget that. Just like everything else in training, keeping it simple can often be the best strategy.
