How do I keep the strenght bars golden?

[MollyFiddler]

Hello people! I'm from Greece and I'm currently learning Spanish.

I already know that with practice the strenght bars stay golden. But I noticed that although I practice some of the words, by either redoing the lessons or just practicing, the strength bars are low.

So my question is there another way that I don't know? Or should I keep redoing or practicing the lessons with these words?

Thanks in advance! :)

P.S. If this is already answered, just add the link to the previous post.

As far as I know, that's all you can do.
