Our Philosophy

Group HIIT is determined to provide programs that are sustainable, fun and challenging. It’s easy to feel intimidated by fitness and have no idea how to get started. You have found the answer and we’re excited you are here. We make our programs as easy as possible to follow and commit to. Login from any device and complete your workout from home or work. The only equipment you need is a set of dumbbells.

Burn Fat Fast

High Intensity Interval Training (HIIT) is one of the most popular and effective forms of exercise for fat loss and evidence based studies continually show they are highly effective at burning fat. Our workouts involve short bursts of exercise at maximum effort. The exercise intervals get your heart rate up and increase the amount of oxygen your muscles use and therefore burns calories fast. After each work interval, you recover for an interval which brings your heart rate down and allows your muscles to rest. These bursts of exercise are shown to create the after burn effect which keeps your muscles burning calories for up to 24 hours after your workout.

What is HIIT?

Build Strength & Endurance

Our programs use strength building body weight movements that engage every muscle in your body. If you are looking for weight training, we recommend Flash Fit which incorporates two dumbbells and weighted movements as well. Within a few weeks of Group HIIT workouts, you should notice an increase in strength and tone. Every workout includes cardio intense movements that get your heart rate up. Every week you should notice your endurance gradually improving as you work through the intervals.

Our HIIT Programs

Quiet, Easy to Follow Videos

We made our videos quiet and easy to follow for a reason. We want you to be able to fit them into your daily life with ease. The only sound the videos have are timer beeps which makes them perfect to do while you watch TV or listen to your own music. There’s no instructor yelling at you, no awful techno music in the background and they can be played on any device.

Ways to Watch

No Gym Required

Group HIIT workouts can be completed at home, work or anywhere you can come together. Save money and time by skipping the gym membership. We have everything you need for total body fitness and it only takes 25 minutes, 4 times per week! With such a small time requirement and affordable cost you'll see how easy it is to make a change that is sustainable.

HIIT is a Scientifically Proven Approach to Fitness

Proven to Burn Fat

Research shows that HIIT burns more subcutaneous fat than low-intensity cardio training by increasing your metabolic rate. This type of fat makes up most belly fat that sits right under the skin. Additionally, high intensity interval training has been shown to yield higher excess post-exercise oxygen consumption (EPOC), which means you'll still be burning calories up to 24 hours after your workout has ended. Studies have shown that, of the calories burned with a HIIT workout, up to 95% of those calories burned occur after the workout.

Research Supporting Fat Burn

Improve Muscle Mass & VO2 Max

Group HIIT workouts use a combination of bodyweight, weighted, plyometric and stabilization movements to keep your body guessing and improve total body fitness. Research shows HIIT improves cardio-respiratory endurance which is measured by VO2 max. During a workout, your muscles pull in oxygen from your bloodstream. Your body burns calories at a rate of 5 calories per liter of oxygen consumed. HIIT increases the oxygen demands on your body which will increase total caloric expenditure during and after the workout. The higher the exercise zone, the more calories per minute you are burning.

VO2 Max Research

Fast, Effective Workouts

HIIT workouts range from 5-30 minutes because they are highly effective and intense. Using challenging movements, HIIT workouts get your heart rate into the anaerobic and VO2 max zones that burn fat. With over 400 movements, each Group HIIT workout is unique so you never get bored and continue to see results. Each program addresses specific goals whether it be to lose weight or build muscle. Therefore, the style of each workout may be more or less intensive cardio or strength focused. We try to find the balance of making a workout challenging while also being enjoyable so you're more likely to stick to the program.

Interval Research

HIIT Fights Disease

Research continues to show the benefits of HIIT for improving specific health conditions such as diabetes, arthritis, cardiovascular disease and even cancer. In a meta-analysis on the metabolic effects of HIIT, published in 2015, researchers found that interval workouts had a higher impact on reducing insulin resistance compared with non-interval training or no exercise. Another study suggests that even one session of HIIT may significantly slow the growth of colon cancer cells.

Research for HIIT Improving Disease

Improves Health of Children

A study of 6-17 year olds showed HIIT can be considered a more effective and time-efficient intervention for improving blood pressure and aerobic capacity levels in obese youth in comparison to other types of exercise.
