Once you start taking a dance class, the only thing you can do in order to get better is to practice. You will need to practice more and more during your dance membership and even at home. There’s a reason why they say practice makes perfect, because it really does that and it encourages you to try out new stuff and explore new ideas.
How much practice do you need?
That being said, a lot of people restrict themselves to the dance studio practice under the supervision of a dance instructor. Obviously that’s not something which will work very well for you if you want to become a better dancer. In fact the thing to keep in mind is that you want all the experience you can get to become a good dancer including all the floor time you can get at the dance studio practicing by yourself.
"The problem is that most people work 8 hours per day and also take a commute to and from work. As a result, practicing outside the regular dance class can be rather limited."
