/Agree with above posts, but for different reasons.
In a small studio or room you may able to get the privacy to teach people this class. Its great for a niche market of people between 15-40 who are fit and looking to learn something new.
The problem with most gyms is the other clients. Some gyms dont allow the weights to be dropped hard, grunting, or other natural gym occurrences.
As long as you’re able to get the group alone it should be a great way to increase your client base.
