How many calories can you burn doing a Jennis Fitness HIIT circuit?

/

Health journalist Carole Beck explains how the Jennis Fitness app's high-intensity circuits impact your metabolism

 

Some of you have been asking about the calorie burn of the Jennis Fitness Circuits in the Jennis app, so we’ve done a bit of investigating. Before we go too deep, it’s difficult to say 'exactly' how many calories you'll burn because it depends on certain factors, including:

 

Your gender – men burn more calories than women

Weight – if you weigh more, you’ll burn more calories

Age – younger people burn more calories than older people

Body composition – if you have more muscle, you’ll burn more calories

How hard you work out – you’ll burn more if you’re someone who pushes yourself harder

Your fitness level – super-fit people are more efficient at producing energy, so burn fewer calories when not exercising

 

But, what we do know is that HIIT and pyramid principles (which have been applied to the Jennis Fitness circuits in the app) may help you burn up to 25-30% more calories than if you jog or cycle at one pace, known as ‘steady-state’ exercise.

 

According to a 2015 study in the Journal of Strength and Conditioning Research, which investigated calorie spend for nine healthy men, HIIT-based workouts came out on top for per minute calorie burn:

 

HIIT workout – burned 12.50 calories per minute

running – 9.48 calories per minute

cycling – 9.23 calories per minute

 

 

You’ll burn 25-30% more calories doing a Jennis Fitness Circuit workout than if you jog or cycle at one pace

Why does a HIIT workout burn more calories?

It’s all about your oxygen intake. When we exercise, our bodies convert oxygen into energy – so high-intensity exercise, such as the workouts on the Jennis Fitness app, will use more oxygen than steady state activities, so lead to a greater calorie burn.

 

What about after the workout?

It turns out that it’s not just the exercise that matters – you’ll burn extra calories after you’ve hung up your trainers, too. This is because of a phenomenon called ‘excess post-exercise oxygen consumption’ (EPOC), also known as ‘afterburn’.

 

This is the amount of oxygen it takes to restore your body to its normal resting state after an intense workout. Remember, your body needs to perform important tasks after exercise, like repairing muscles and filling energy stores – and because all these jobs require oxygen, they also burn calories.

 

High-intensity exercise – like the Jennis Fitness Circuits in the app or the HIIT-inspired Outdoor Body Blasts – produce a longer EPOC period than a jog or cycle ride performed at one speed, according to a 2017 study in International Journal of Exercise Science.

 

 

Metabolic rate was still raised 22 hours after a high-intensity interval resistance training workout when compared to a traditional resistance training workout

What about fat burn?

HIIT workouts, such as the Jennis Fitness Circuits, are effective at reducing body fat – and not just stomach fat, but also the internal fat that can accumulate inside your body and surrounds your organs.

 

A 2018 US study found that 12 weeks of HIIT workouts led to a decrease in total body fat and an increase in lean body mass for women. One theory is that this type of fat burn is a result of a raised metabolic rate after an intense workout.

So, if you’re looking to lose weight, get fit and do it efficiently, the circuits featured in the Jennis Fitness app could well be the answer!
