Frequently asked questions about HIIT
What is a HIIT class?
HIIT stands for high intensity interval training. The workout alternates between short bursts of maximum effort and brief recovery periods. This class format helps improve cardiovascular fitness, burn calories and build strength while keeping the workout efficient and engaging.
What should I wear to a HIIT class?
Wear breathable gym clothing and supportive training shoes that allow you to move comfortably during fast-paced exercises. HIIT workouts often include jumping, running and bodyweight movements, so flexible sportswear that supports a full range of motion is recommended.
What are the benefits of HIIT training?
HIIT training improves cardiovascular fitness, endurance and muscular strength while helping burn calories efficiently. The intense intervals increase heart rate quickly and can support fat loss while building overall fitness in a shorter workout compared with traditional steady-state cardio.
How many calories can you burn in a HIIT class?
A HIIT class can burn between 400 and 700 calories depending on the intensity of the workout and individual effort. The alternating intervals of high intensity exercise and recovery make HIIT training an effective calorie-burning workout.
