30 minute Group Classes. HIIT stands for High Intensity Interval Training, which is working for short durations of time at a high intensity, alternating with periods of rest – but don’t let the high intensity intimidate you! We incorporate strength, flexibility and agility exercises in our workouts for a full body workout each class. Our workouts can be tailored to any fitness level – the important aspect is getting your heart rate up, your body moving, and having a little fun! Plus, classes are 30 minutes long, so you can fit them in your busy day!
