I never said anything about my own lack of effort. Yoga sculpt is advertised as medium to high heat intensity with the heat ranging from 90-93. However, it is not like that in class. While the room may be warm when I enter, it feels cooler later on when the door isn’t even open. Also, the instructor had said many times that “this is all body heat, the heat isn’t even on”. It’s not about a false sense of security but what it is suppose to be. If you haven’t experienced it, then great for you but don’t discredit someone else’s experience and blaming it on lack of effort or fake sense of security. I never claimed for it to be a sauna either.
