He gives three or four different classes at the same time, in the classroom and by zoom, so every time you finish your exercises you have to wait for him to finish talking to all the other students so that he tells you how to continue and so with each exercise. The classes last 40/45 min. It gives you either all of your arms or all of your legs, it doesn't intersperse, so you always end up exhausted on one side or the other (it could be that since he teaches so many classes at the same time he gets dizzy if he changes, I don't know). I went because the traumatologist sent me for a health problem and I had prohibited exercises, he gave me the same and when I asked him to give me another one because it hurt me, he yelled at me "so tell me what you want to do!". I kindly told him that I would do what he told me, that the teacher was him but that what he gave me I couldn't do. It was the last time I went, obviously. My friend too.
