Is 15 Minutes On A Treadmill Enough To See Results?

The treadmill is the most popular cardio machine in the gym or at home. Is 15 minutes a day enough to see weight loss and/or health improvements? Here’s what you want to know.

Using a treadmill at moderate intensity for 15 minutes can burn an average of 144 calories (weight and speed-dependent). This isn’t quite enough for significant weight loss and health improvements. HIIT workouts can help get more benefits in 15 minutes. 

What can you expect from working out for 15 minutes on a treadmill? And what can you do to make the most of your running? Find out below.

What Does 15 Minutes On a Treadmill Do?

Calories Burned in 15 Minutes On a Treadmill

15 minutes on a treadmill or any other machine is not a lot. If we assume 15 minutes of work at moderate intensity, you’ll burn about 144 calories. For reference, a 50-gram candy bar has about 250 calories. 

15 minutes on a treadmill at moderate intensity burns about 144 calories.

Those 144 calories are an average. Depending on your weight, speed, and incline, the amount of calories you burn on a treadmill in 15 minutes can range from 100 to 250. Walking burns a lot fewer calories than jogging which in turn burns fewer calories than running. How heavy you are and the incline you set the treadmill to are also very important.

Is 15 Minutes On a Treadmill Enough To Lose Weight?

15 minutes of moderate exercise on a treadmill is not enough to notice any significant weight loss unless you’re also in a calorie deficit through your diet. To lose weight, the amount of calories you eat is very important. Let’s assume you eat exactly enough to maintain your weight for a moment.

A pound of fat contains about 3500 calories worth of energy so 144 calories a day isn’t going to make you lose weight very fast. It would take about 24 days to lose one pound. While that’s better than nothing, it’s probably not the result you’re looking for.

Working out at low to moderate intensity on a treadmill for 15 minutes a day will result in losing one pound of weight in about 24 days. That assumes you eat enough to maintain your bodyweight without doing exercise.

A 250 to 500-calorie deficit a day is recommended by most dieticians. This makes you lose weight much faster. However, creating a 250-calorie deficit in 15 minutes on a treadmill is not easy, let alone 500 calories.

For example: a 160-pound person has to run 6.5 Mph on a 5% incline to burn 250 calories in 15 minutes. While that’s not impossible, it’s not something beginners and people starting their fitness journey will be able to do.

15 minutes on a treadmill a day in addition to a small deficit in your diet will result in good results.

Benefits of Running 15 Minutes a Day on a Treadmill

Weight loss isn’t the only benefit of running on a treadmill though. 

There are also significant benefits for health, performance, and endurance. For health and performance, 15 minutes is a good start but it’s not quite enough for most people, especially if you’ve got a sedentary lifestyle.

15 Minute treadmill workouts every day can improve many health, performance and endurance factors compared to not working out but it’s not an ideal duration.

30 minutes a day/5 days a week (150 minutes a week) of moderate exercise is the minimum recommended amount of exercise for heart health. And that’s on top of your normal movements during the day. Those 30 minutes already assume you take at least a couple thousand steps a day.

Any exercise is better than no exercise

That said, if you don’t do any exercise now, 15 minutes is much better than doing nothing. There will be positive effects on your health, endurance, weight, etc. It’s just that it’s not quite enough for the average person to be healthy, especially if you’ve got an otherwise sedentary lifestyle. 

Tips To Optimize 15 Minute Treadmill Workouts

If 15 minutes is all you can do now, see if you can decrease the speed and/or incline on the treadmill. It’s better to do more minutes at a lighter resistance level than the maximum resistance you can handle for 15 minutes. Wear a heart rate monitor to make sure you pace yourself. Staying within the right heart rate range will help you optimize the duration and calorie burning. 

If 15 minutes is really all you can do at the moment, that’s where you have to start off. In that case, don’t expect too much weight loss at first. You have to build up your health and fitness to a point where you can do at least 30 minutes in one workout. This can take a while. Give yourself some time, just be consistent and add a few minutes to every workout. You’ll have to push yourself a little further every time but don’t go too crazy all at once. Adding 5 minutes to every workout is a good target. After you hit 30 minutes, then increasing speed and/or incline is a good idea. 

15-minute workouts on a treadmill are a place to start but it should be a starting point on the way to better health, endurance, and performance. 

If you only have 15 minutes of time and absolutely can’t free up any more time, look into High-Intensity Interval Training. This is not a beginner workout and can be tough. It’s much tougher to do this than steady-state cardio (constant heart rate) which burns more calories in 15 minutes. It also has a bigger impact on conditioning. For weight loss, longer but lower-intensity workouts are better but if you’re limited by time, it’s the best option. 

How Do Treadmills Burn Calories?

The more you weigh the more calories you will burn during an exercise. There are two important factors in weight: Muscle mass and body fat. The greater your muscle mass, the quicker you will burn calories. This is because more muscle can burn more calories just like a bigger engine burns more fuel in a car. However, if you are heavier because of higher body fat, you’ll also burn more calories because you’re moving more weight around.

One thing that doesn’t depend on your weight is the length and intensity of your workout. The longer your workout and the higher intensity, the more calories you will burn. You can increase the intensity of your workout by running at a higher speed, increasing the resistance, and using High-Intensity Interval Training (HIIT)

High-Intensity Interval Training (HIIT) Is a great way to burn more calories in a short period of time. A good interval timer is going to make HIIT workouts much more enjoyable. Check out the GymNext Flex timer. It’s super easy to set up and control contrary to most other interval timers making the setup for any workout a breeze. 

However, not everyone is in a position to do very high-intensity workouts and use HIIT. In that case, you can get the same weight loss results as a high-intensity workout by doing a low-intensity workout for a longer amount of time. As long as you are continuously moving, you will burn calories. In that way, you can keep going at any speed with any resistance level that you want until you have burned the number of calories you desire. However, to burn a meaningful amount of calories will take more than 30 minutes.

In the end, your muscles moving your legs and your heart pumping all the blood and nutrients around is what burns calories. The harder it is for your muscles and heart, the more calories you burn. But that intensity can be replaced by a lower intensity for a longer duration.

If you have a built-in calorie counter on your treadmill depends on the type and how fancy it is. That said, most new treadmills have a calorie counter and even a heart rate monitor built in. Don’t forget to set your weight if possible: That makes the counter a lot more accurate.

The question is if you can see results by using a treadmill for 15 minutes a day. You burn more calories in a certain amount of time if the average intensity in that time is higher. So if you run as fast as you can for 15 minutes on the treadmill, you’ll see more results than if you walk at a leisurely pace for the same 15 minutes. However, it also depends on your diet but more on that later.

A 155 lbs. person running at 5 MPH burns 288 calories per 30 minutes. That same person running at 6 MPH burns 360 calories per 30 minutes. That means about 144 calories per 15 minutes @5MPH.  Since a pound of fat has about 3,500 calories. If you eat exactly enough calories to maintain weight without exercise, doing 15 minutes on a treadmill means you lose a pound of fat in about 24 workouts. That’s not very effective. 


How Often Should You Use a Treadmill?

You can run on a treadmill every day if you want and you recover quickly enough. Adults are recommended to get at least 150 minutes of medium-intensity to vigorous exercise a week. Typically, people reach this by working out for 30 minutes a day, five days a week. This way you allow the body time to rest and recharge.

Exercising at least 150 minutes a week is recommended for preventing weight gain and general health. If you are looking to increase weight loss, however, you should be striving for around 250 minutes of exercising a week (while maintaining a healthy diet, of course). In that case, it is recommended to work out 45 minutes to an hour for five days a week.

Keep in mind, those 30 minutes recommendations assume that you have a moderately active lifestyle outside of exercise. That means at least a few thousand steps a day. If you don’t get to a few thousand steps a day outside of exercise, getting up to 45 minutes a day is better. 

There is nothing wrong with using a treadmill more than five days a week, as long as you are not doing long high-intensity sessions each day. If you want to run every day without days off, it’s better to do longer but low-intensity workouts. However, rest days are always a good idea. Your body might not start complaining the first few weeks but if you keep up the schedule for a long period of time, you probably get some weird aches and pains that could have been prevented by taking time off.

Combining cardio exercise with resistance training will make your workouts even more effective. Varying your workouts makes them less repetitive and building some muscle raises your resting calorie expenditure which means you burn more calories while sleeping! Stronger and bigger muscles also make you look better and compound the physique improvements you get from fat loss.

What Areas of The Body Do Treadmills Target?

Treadmills use certain body parts more than others. However, that doesn’t mean you can use it to spot and reduce fat in the used areas. A treadmill uses your hamstrings and glutes but that doesn’t mean your body will strip the fat of those body parts, fat loss doesn’t work that way. Burning calories will lower your overall body fat percentage but where that fat is removed depends on factors like: Genetics, age, gender, and hormone balance.

It’s better to think of running on a treadmill to burn calories and therefore lose overall body fat while improving cardiovascular health and strengthening your lower body muscles. Consistently running on your treadmill will start removing fat from part of your body.

Besides burning calories, treadmills are great at improving cardiovascular health. Running on a treadmill is very similar to running outside but there are some differences. However, from a cardiovascular perspective, they are very similar.

Aerobic exercise makes your heart and lungs work harder to get blood and oxygen to your muscles. This is the process that is strengthening your cardiovascular endurance while using a treadmill.

Regular cardiovascular exercise also has benefits for mental health, digestion, calorie partitioning and many more processes in your body.

Lower Body

Treadmills don’t use the upper body in a meaningful way. Sure, running is a full-body workout and you move parts of your upper body but they don’t get activated to a large degree. Especially not if you compare it to lower body activation.

Treadmills mainly target the lower body. Good treadmills have the option to change incline settings to target different leg muscles, namely your glutes, hip flexors, quadriceps, hamstrings, and calves.

Suggested: Can you walk on a treadmill without shoes?

Running or walking on a flat treadmill will target the quadriceps more. The more you increase the incline, the more the focus pivots to the rear of the legs. So that means the higher the incline the more focus on the glutes, hamstrings, and calves.

Also, increasing the incline dramatically increases the amount of calories you burn because the intensity is much higher. Just like running outside on flat ground is much easier than running up a hill.

Unlike elliptical trainers, exercise bikes, or rowing machines, running on a treadmill means your feet impact the belt continuously. This can cause your joints and spine to start aching and your recovery time to be longer. Getting a high-quality treadmill with good damping in the belt will dramatically reduce the impact on every stride which means you recover quicker and can work out more often. In the long run (pun intended) this means you’ll see much better results with less injury risk.


With every stride, your body naturally contracts your abs and other core muscles to keep you balanced and to keep a straight posture. This will strengthen the core. The faster you run, the higher the core activation tends to be. If you’re untrained, you’ll get some core-strengthening effects from running. However, if you’re more advanced, just running isn’t going to be enough if you want to strengthen the core.

Can you get abs just from running on a treadmill? Find out here.

Running doesn’t activate and train the complete core either. And since it’s necessary to have a strong core for high-intensity exercise, it’s a good idea to do some separate core strengthening exercises besides running. Some simple bodyweight exercises can dramatically increase core strength in a few weeks if done regularly.

Are you looking for visible abs? Running on a treadmill still plays a big role. That’s because having visible abs requires the right combination of the ab muscles being big enough and having a low enough body fat percentage. A treadmill is a very useful tool to reduce body fat percentage. To really make your abs pop, it’s a good idea to do more ab exercises apart from running.

What Can You Do To Make Your Treadmill Workouts More Effective?


The key to optimizing the results of your workouts, whether it’s running, weightlifting or any other activity, is to eat balanced and nutritious meals. To get the most out of your physical activity, you have to be giving your body sufficient energy to perform. Some forms of energy are better than others. Paying attention to total calories, macronutrients and micronutrients are all important to giving your body the best fuel.

Now, what is considered to be a balanced diet depends on what you are trying to accomplish. There will be a different amount of calories you should be consuming a day and a slightly different ratio of carbohydrates, fats, and protein (macronutrients).

Cook your own meals and try to avoid processed foods as much as possible. A good target to shoot for is to get 80% of your calories from whole foods. It’s very tough to eat 100% whole foods and shooting for 80% is more likely to give you enough leeway to be able to stick to it.

Typically, your ratio of macronutrients should be:

  • 30–35% of your calories from protein
  • 40–50% of your calories from carbs
  • 10–30% of your calories from fat


There are a lot of different ideas about what the optimal ratios of macronutrients are but basically, you want to get enough protein (0.6-0.8 grams per pound of bodyweight) and enough healthy fats (up to 30% of total calories) and fill the rest of your calorie needs with carbs.

To lose weight, you need to be taking in fewer calories than you are going to burn from exercising. Using a calorie tracker and calculating your Base Metabolic Rate (BMR) are useful tools do discover how many calories you take in and use during a day.

A kilo of fat has 7700 calories. So by consuming 550 calories fewer per day than you use, you’ll burn through a kilo of fat every two weeks. Running helps increase the amount of calories you burn on a day (about 288 per 30 minutes). That means if you eat 250 calories less than you need and burn 300 more calories through working out you have a deficit of about 500 calories.

So after eating right and running for 15 minutes 5-6 days a week (creating a roughly 500 calorie deficit), you’ll lose about 2-3 kilos (4.4 – 6.6 lbs.) after 4-6 weeks. For most people this won’t be enough to reach their goal but it will be visible. After 8-10 weeks your weight loss would be about 4-5 kilo (8.8-11 lbs.)

It’s not a good idea to create a bigger calorie deficit than about 500 calories per day unless advised by a healthcare professional. Larger calorie deficits are more difficult to sustain for long periods of time and make it more likely you won’t have the willpower to keep going.

A note about protein: It is a myth that you need to consume significant amounts of protein to gain muscle. Strength training is how you will build muscle! Yes, your body needs protein to repair and grow the muscles but, if you consume more protein than your body needs in a day, it will be converted and stored if it exceeds your daily calorie needs. Thus, eating so much extra protein you go over your daily calorie goal, will actually go against your goal and reduce the efficiency of your workout. About 0.6 – 0.8 grams per pound of bodyweight is a good goal.

Strength Training Exercises

As you can read above, running mainly strengthens the muscles in the lower body. To strengthen other muscle groups or focus on some specific ones, you use strength training. Combining the calorie burning and cardiovascular benefits of running on a treadmill with strength training is very effective and will multiply the effect you would get if you’re only doing one of the two. Lowering body fat and increasing muscle mass is a winning combination to improve your physique.

The best way to include strength training exercises in your running workouts is to do them after. That’s if you want to focus on weight loss. If you want to focus on muscle building, it’s better to do the strength exercises first. 

It’s best to do a full body strength workout that targets all body parts. If you don’t want to do all the body parts on one day, you can split them up as well. It’s best to hit all the body parts twice a week. Training your whole body creates a better overall physique and prevents major muscle imbalances. It also means you create more real world strength that’s useful in daily life.

Stretching Before And After

Before and after any workout it is a good idea to stretch. If you begin working out without warming your muscles, you are more likely to injure yourself during your exercise. Stretching is a light way to warm up your muscles and prepare them to be used.

Good pre-workout stretches include:

  • The Pike Stretch– Start by standing with your legs shoulder-width apart and reach down to put your hands in front of your toes. You’ll then slowly walk your hands forward while keeping them shoulder-width apart and keeping your legs straight. Essentially, you are walking yourself into the yoga stretch “downward dog.” Stay in that position for 30 seconds. This will stretch your hamstrings and calves.
  • Trunk Rotations– Start lying on your back with your hips and knees bent and your feet flat on the floor. Your arms should lay straight at your sides. Squeeze your shoulder blades and flatten your neck to the floor while rotating your legs to the left. As you twist, your right shoulder blade and arm should remain flat on the floor. Hold that position for a few minutes and then slowly return to the starting position and rotate your legs to the right side. This will stretch your shoulders, legs, and core.
  • Lunges– Lunges are an example of dynamic stretching, a way to stretch by constantly moving as opposed to holding a pose for a long amount of time. Since lunges target the leg muscles and back, doing a set or two of them before getting on the treadmill can help get the blood flowing through your legs and prepare them for endurance.

Good post-workout stretches include:

  • Chest Stretch– Start by standing with your feet slightly wider than shoulder-width. Place your hands on the back of your head with your arms raised and elbows pointed to the sides. Bring your shoulder blades together as you press your elbows backward.
  • Seated Glute Stretch– Start by sitting in a chair with one foot flat on the floor. Place your other leg so that its ankle is over the knee of the foot flat on the floor. Slowly bend forward while keeping your back straight until you feel a slight pull in your hips and glute muscles. Hold that position for 30-60 seconds and repeat with the other leg.
  • Cat-Cow Stretch- Start with your hands and knees on the floor, with your spine straight and relaxed. As you inhale, press your chest forward as if making your back into a bowl. As you exhale, relax your shoulders and round your spine upward, and press your hips forward as if making your back into a hill. Relax your shoulders and continue to go between these positions for a minute.
