How to set appointment twice a week

[Renato Pontefice]

I need to sign up my palestra appointment twice a week:
On Monday from 16 to 17:30
On Friday from 18 to 19:30

For one day I use:

**  Io palestra  <2022-10-03 Mon 18:00-19:30 +1w>

But to add the second time? Do I add a line? Or can manipulate this one just 
adding the second appointment?

(I need this not just for palestra but for more things…)

Thank you

Renato
