Make the Switch to HIIT, High Intensity Interval Training

Over the years, HIIT has gained a lot of popularity and it’s mainly due to the many benefits it has! HIIT workouts involve short periods (30-60seconds) of intense exercise followed by low intensity recovery periods. In a shorter period of time than your traditional cardio exercise like running, you are able to improve more muscle groups at once, burn more fat, and improve strength, endurance and cardio in a single workout.

An effective HIIT workout can range from anywhere between 5 to 30 minutes. At ReformFIT, our workouts are 50 minutes in total including a 10-minute warm up and cool down making it an ideal length!

Below are 5 health-supporting benefits of High-Intensity Interval Training.

 

1. AFTERBURN EFFECT

During a HIIT workout, the goal is to push your heart rate and intensity up to 50-60% VO2 Max. This results in stimulating EPOC (Excess Post-Exercise Oxygen Consumption) and is known as the Afterburn Effect¹. By stimulating a higher EPOC through HIIT, it consumes more oxygen, which creates a bigger deficit in the body. As a result, your metabolic rates can increase up to 24 hours after a HIIT workout to replenish oxygen, ATP and rebuilding muscles, making it burn more calories and fat long after the workout is over!

 

2. BURN MORE CALORIES IN A SHORTER TIME

A study has shown that a 30-minute HIIT workout was able to burn more calories than the traditional weight training, running and biking workout that would last much longer². So not only are you saving time but also being more efficient with your body during a HIIT workout.

 

3. WEIGHT LOSS

Since HIIT burns more calories during and after the workout in a shorter period of time, it can be a great way to help with weight loss along side proper nutrition and lifestyle changes.

 

4. TARGETS MORE MUSCLE GROUPS

Due to the type of exercises used in HIIT, you are more likely to utilize different muscle groups to perform each exercise. For instance, in one single HIIT workout, you will be performing exercises that targets, lower body, upper body, core and full body such as burpees, squats, push-ups etc.

 

5. LOWERS BLOOD PRESSURE and BLOOD SUGAR LEVELS

Research has shown that performing HIIT workouts 5 days a week for six weeks resulted in improvements in blood pressure and better control in blood sugar levels³. That being said, this type of exercise can be helpful in improving overall health, and can play a role in preventing chronic illnesses such as cardiovascular disease and diabetes.
