I wish the sculpt classes were heated more...at least consistent as it seems each teacher keeps the temp at whatever they want...different from class to class. It is frustrating because I have been to many other sculpt classes in other cities and every one is much hotter and more difficult than any of the Dallas studios. This is the same for the Henderson studio...sculpt classes are just not hot enough. And this isn't just me...many people comment outside of class how they wish it were hotter. You come to a sculpt class to not only get a good workout...but to sweat and detox as well.
