Cardio/HIIT (High-Intensity Interval Training) is a form of exercise that alternates between high-intensity periods of exercise and short periods of rest. This type of training is designed to increase heart rate, burn calories, and improve overall cardiovascular fitness. In a typical Cardio/HIIT class at YogaWorks, participants can expect a variety of exercises, such as jumping jacks, burpees, and high-knees, performed at a high intensity for short periods of time, followed by a brief period of rest. The class may also include bodyweight exercises and the use of equipment, such as kettlebells or resistance bands, to provide an extra challenge.
