[Vocabulary] Gymnastics lesson/class

[angelene001]

1.Every Saturday, I've got a gymnastics lesson.
or
2.Every Saturday, I've got a gymnastics class.

Meaning I spend an hour at the sport center and do exercises to help my spine, to make me more flexible.

Are 'lesson' and 'class' interchangeable when I talk about things like drama, dancing, karate?
Or maybe 'class' is when you do something with a group, and 'lesson' when it is one-on-one?

For me, if you go to a gymnastics class, you are involved in the actual sport of gymnastics - tumbling, vault, beam, asymmetic bars, pommel, rings, high bar. If your class is for spine stretching, it is probably yoga or pilates or simply a "stretching class".
