I allow a maximum of 6 people per class so you get live adjustments at all time as if you were in my actual studio. I also use a large iMac screen so I can monitor closely all attendees at the same time which means you get feedback and of course encouragement throughout the class. The added benefit that I find is my online classes are helping to keep the community and social spirit going in these very trying times.
I also offer competitive pricing (same as many other studios that are allowing 15 or more people per class and where the teacher is forced to swipe between screens).
Classes and 1 hour and I use the Zoom conferencing app which is free for you the customer. Zoom is a very reliable platform with stable video and audio streaming.
