Replacement for Single bar shoulder mobility

Hi, i just started level one two weeks ago and being stuck at home due to the ongoing pandemic i was wondering what i should replace the "Single bar shoulder mobility" exercise with since i don't have any access to rings or a bar?

Thanks in advance,
Amir

Hi Amir, for the moment if you do not have them simply skip this class. You need to buy a doorframe bar, is the more simple solution.
