The closing step is a step with weight
In the side chasse in Cha-Cha, the middle step looks unremarkable: One foot comes to the other, and you immediately move on. That is exactly why it is often only tapped. Then your weight stays on the supporting leg. That leg is supposed to move sideways again, even though it is still supporting you. This can lead to pulling, a late step, or a small hop.
Feet together does not mean your weight should stay on both feet. The foot that comes in becomes your new supporting leg. The other is then free for the final side step. Keep your knees flexible as you bring your foot in, and straighten the supporting leg in a controlled way without locking it. A deep dip before every step would create just as much instability as pushing upward. Extra hip movement cannot replace transferring your weight either.
This exercise isolates the side step. You can find out how it fits into the dance in Getting started with Cha Cha, steps and music.
