Replace the label with a task
A side can be less practiced at one task and useful at another. Calling it the bad side does not tell you what to practice. Name the actual difficulty: receiving the ball, finding support, controlling a release, or recovering after a turn.
Ambi Elite begins with an observable relationship. Which contact supports you? Which side executes? What happens when you reverse them? These questions turn a broad ambition—become more two-sided—into a session you can organize.
Give it comparable work
Comparable does not mean identical demand. The unfamiliar configuration may need a shorter distance, less speed, or a simpler decision. Preserve the purpose of the task while making its difficulty manageable.
Choose one skill and note a starting condition: object, target, distance, pace. Work deliberately in each configuration. If one demands a modification, record it. That makes later comparisons more useful than a vague feeling that it looked better.
Order is part of the design
In a study of 52 right-handed children, practicing basketball dribbling with the non-dominant hand first produced advantages in retention and an alternating-hand transfer test compared with the reverse order. It is a specific result in a specific task, not a universal rule for every sport.
Stöckel, Weigelt & Krug · 2011 ↗A practical starting point
Use an NST module to define the relationship. In the acquisition week, give the unfamiliar action patient attention at a controlled demand. In the application week, add one useful challenge: a direction cue, a target change, or a modest increase in pace.
Return to the original task after a break. Ask what remained, what became more repeatable, and what still needs a simpler version. That is a practice record you can build on.
The goal is not to erase a preference. It is to create more usable choices when the play no longer favors it.
