NetLiner adjustment and progression guide: from amateur to pro
How to step up your level so training evolves with you and never stagnates.
One of NetLiner's strengths is that it lets you progress in stages. It is not a static tool: you can adjust difficulty depending on the player's moment and avoid both stagnation and overload.
In the initial phase, a lower height helps consolidate consistency and confidence. In the middle phase, the player already starts working on spin and depth control with more intent, feeling that topspin appears as a natural solution.
The advanced phase is designed for more intense sessions, where better racquet acceleration and a finer reading of trajectory are required. If you add zone references on top of that, you also introduce a tactical layer without complicating the session.
Takeaway: progressing well doesn't mean training harder, it means training with the right level of challenge at every stage.
