Yes, the challenging infrared heat and calorie burn from HOTWORX classes can support weight loss goals. However, diet and nutrition choices remain most important for sustainable fat loss. For best results, experts suggest combining 2-3 HIIT sessions like OrangeTheory for max calorie burn with 2-3 sculpting workouts at HOTWORX for strength/flexibility. The sauna heat may provide additional metabolic benefits. Just remember results require consistency, hard work and a healthy diet.
