Using an incline treadmill makes walking, jogging, and running more relaxed than you would outside. That’s because you’re not exposed to weather elements that might hinder your fitness progress. Here are the benefits of using an incline trainer.
- You burn calories and lose more weight than you would when you use a flat surface. Besides, walking and running on an incline is also the same as taking uphill routes, which makes your body shed more fat.
- The incline feature on the treadmill is the right way for you to exercise more without increasing the workout speed or time. As a result, you put less stress on your joints and leg muscles.
- Using the incline builds up the leg, glute, and calf muscles. Besides, you can control the elevation and gradually increase the height as your muscles strengthen.
- The more you walk on an incline and raise your heart rate, your heart muscles become more energetic, and your blood pressure becomes low.
Care & Maintenance Tips
Even if you have the best incline treadmill in your home, it can only function if you care for it. These guidelines will help you to maintain your machine to prolong its life.
- After each session, dip a soft cloth in water and wipe off the dirt from the machine’s frame. Be careful with the console area and avoid harsh chemicals or abrasive cleaners.
- Try to align your treadmill’s belt by regularly adjusting the bolts on the sides.
- As you use your machine, the belt’s tension will change and might damage the deck or motor if left unchecked. You can turn the treadmill and slowly stomp your foot on the belt, and if it slips, tighten the bolts.
- Only place your treadmill on a level floor, and if your surface is non-leveled, adjust the treadmill’s supports.
- Keep the power cord secure and away from the machine.
- Keep the motor clean and don’t outstep its design specifics.
Treadmill Safety Tips
Incline trainers can cause injuries if you don’t follow safety rules. These few tips will help to limit treadmill risks.
- Be Prepared
Though there is a difference between running indoors and outdoors, you still have to use the right kits to get a comfortable workout experience. Some of the things you need include a hand towel to wipe sweat, headphones to listen to music, and a water bottle to keep your body hydrated.
- Use the right trainer’s clothing.
Get a good quality short pair and t-shirt to wick away moisture from your body. In other words, your inner material should be breathable to keep you cool and comfortable. You should also get a good running shoe pair with the right fit and bottom grip.
- Check your fitness level.
Run for short intervals and check how you feel, then make necessary adjustments about your heart rate. This should continue until you develop enough stamina to run much longer.
- Start with Warm-up Exercises
Before you use your incline treadmill, you need some basic exercises to activate your body to the running mode. Start first slow, and gradually increase speed. These pre-treadmill exercises do warm up your blood and make your workout more effective.
- Avoid the handrails
Try not to commit the mistake of using the machine’s handrail for your support. Keeping off the bars will make the exercise as effective as running in a natural environment.
- Stay Hydrated
Keep your water bottle handy whenever you are running on your home gym. Luckily, many of our reviewed choices come with bottle holders for easy access to water. Try to maintain a well-hydrated body, and don’t wait until you feel thirsty before you take a sip. You can drink water before you start and at every ten minutes of your workout.

1. Should I walk fast or use an Incline?
Ans. Walking is also a practical workout routine, but with an incline trainer, you’ll create more impact on your leg muscles.
2. Does Incline treadmill burn belly fat?
Ans. When you walk uphill, you place much demand on your body, which increases your pulse rate and burns extra fat. So, training with an incline burns calories of your whole body, including your belly.
3. Is walking at an incline better than running?
Ans. Walking impacts only your low body parts, but incline walking affects your lungs, heart, and leg muscles and joints.
4. Is incline running on treadmill terrible for the knees?
Ans. It won’t have any adverse effect on your knee if you start slowly and gradually increase speed and incline. Incline walking is, however, better for your knees than using a flat terrain.
5. Which should I choose between the incline treadmill and Elliptical?
Ans. If you want to work on your arms and body muscles, an elliptical is a better option. However, an incline treadmill offers different workout options, and you can vary the speed and elevation.
6. Is there any benefit for changing incline and speed during a workout?
Ans. Each incline level has a different effect on your muscles. For instance, muscles like glutes, calves, and quads are strengthened when you go much higher. But when you run fast on a flat surface, you energize your lungs and heart muscles. So, you should change the speed and regularly incline to get the most from your treadmill.
7. Does incline treadmill make your legs bigger?
Ans. You get the same benefit of running uphill when you use an incline treadmill. Of course, the up and down movements become intense as you run uphill, creating more impact on your leg muscles. Thus, your leg muscles will build.
