Short-Stepping the Jerk: It's Not Your Footwork
Don’t waste your time with footwork drills!
If your split position is good with light jerks but short with heavy jerks, you don’t have a footwork problem—you have a dip & drive problem.
Three main reasons for this, which are often combined:
Inadequate drive means not enough acceleration to create the time and space to step into your full split.
Any forward shifting during the dip or drive will tend to make the front foot land too early and short.
And if you lean your chest forward too much too soon, it will pull your hips back and push your front foot down, making it land short.
If your bad footwork is a symptom of another problem, training your footwork won’t solve it any more than treating the symptoms cures a disease.
Invest your time into diagnosing the real problem and then addressing it.
