You can reap several benefits from a 30-day treadmill HIIT workout plan. In fact, a HIIT workout on one of the best treadmills will help boost fitness, burn fat and trigger a release of feel good endorphins. 

But what exactly is HIIT? 

Chris Appleton is a MyProtein PT. He explains that HIIT, or high-intensity interval training, involves working very hard (often near your maximal intensity) for a short set period before a short period of rest. 

‘An example may be 45 seconds of work in each exercise, followed by 15 seconds of rest before executing another set. This type of workout typically does not last very long as it is unsustainable. However, one of the main objectives is to maintain a very high heart rate for the duration of the workout, which may only last for 20-30 minutes.’

He adds that HIIT training may also be defined with reps, such as completing 20 reps as fast as possible before moving on to the next exercise.

The benefits of HIIT

Chris says that there are several ways that HIIT can benefit you. Firstly it can burn a lot of calories in a short amount of time, which can help you lose fat.  In fact there are studies that have shown how a 30-minute HIIT workout can burn a staggering 450 calories. However, you can track your calorie burn on one of the best fitness trackers, for a more accurate measurement.

Chris explains that HIIT causes your metabolic rate to remain high for hours after exercise. This is known as the ‘afterburn’ or Excess post-exercise oxygen consumption (EPOC). Essentially, your body continues to use oxygen to help it get back to its rested state after such intense intervals, and this in turn leads to more calories being burnt.

Because of this, Chris adds that HIIT could also improve your body’s oxygen consumption. Plus it can help reduce your heart rate and blood pressure, which in turn can lower the risk of cardiovascular diseases.

Another benefit of HIIT? Turns out that you might even gain muscle from HIIT workouts, including our 30-day treadmill HIIT workout below. During a treadmill HIIT workout, you'll be partaking in sprints. Because sprinting involves short, sharp, explosive movements, all the lower body muscles are recruited, aiding muscle growth.

Your 30-day treadmill HIIT workout

Chris has designed a 30-day treadmill HIIT workout. 

‘We start by building some fitness and endurance but eventually, we hit the sprints to really get things sweaty!' he tells us. 'Each session needs to employ the progressive overload principle by increasing the incline or speed each time. This way, you are guaranteed progress.’

For this workout, your warmup walk is a brisk one so keep it comfy but slightly out of breath.

Look to add at least 0.5 to your speed each session. For example, if your starting run speed is 6.0, your second session starting run speed is 6.5.

Each person will vary in their running/walking speed and each treadmill can vary between KPH and MPH but will go by the same principle on screen.

Tips to help with your 30-day treadmill HIIT workout

Chris explains that staying hydrated throughout your workouts is important.

‘Ensure you are taking on fluids before, during and after your run to keep fuelled. Drink in small sips rather than gulps though to reduce your chances of developing a stitch.

‘Replace your lost fluids once you are finished too.’

Before you run, you might want some fuel. Chris explains that something high in carbohydrates and lower in fat, fibre, and protein is a good idea.

You could try a peanut butter sandwich or a banana.

‘Aim for around 100 calories 45-60 minutes before your run.’

After your run, opt for something that contains a ratio of 3:1 in carbs and protein to recovery sufficiently. 

‘Whey Protein is both tasty and convenient to get that hit of protein. A bagel with some peanut butter is works too or oat cakes with smoked salmon.'

Chris adds that it’s best to avoid high-fat foods before exercise such as fried foods, cheese, hamburgers, or bacon. These can feel like they’re sitting heavily on your stomach as they digest slowly. 

Caffeine might also be best avoided.

‘Coffee or other caffeinated beverages can cause stomach issues on a longer run. You also don’t want to increase your heart rate - something that caffeine will do - right before doing an exercise that also increases your heart rate.’

As well as hydration and fuel, ensure you’re wearing one of the best running shoes for men or best running shoes for women. You’ll need plenty of cushion in your footwear to help limit the impact on your joints of all that running!
