How Curved Treadmills Work

Curved treadmills are manually operated and work when the user begins to create momentum. When the user hops on the treadmill, they will start walking or running, and this action will move the treadmill belt. If the user slows down or speeds up, the treadmill belt will follow. This is one of the reasons why curved treadmills are considered safer compared to traditional treadmills.


Benefits of Curved Treadmill Workouts

Curved treadmill workouts offer many advantages compared to a standard treadmill. When you use a curved treadmill, you will need to use more energy and will also use more muscle groups. The curved treadmill asks more of the glutes and hamstrings. It also minimizes the impact on your joints because the curved design forces users to run on the balls of their feet and keep good posture. In fact, studies show that working out on a curved treadmill burns 30% more calories than working out on a standard treadmill.


Choosing Quality Curved Treadmills

Size vs. Space

You want to make sure that you have enough space in your home to house your curved treadmill. We recommend measuring several areas in your home to see what your options are and then comparing those dimensions with the dimensions in our product list.

Max User Weight

You will want to consider the maximum user weight when purchasing a curved treadmill. Make sure that every person who will use your treadmill is within the max user weight.

Assembly

You may want to consider adding the assembly onto your purchase if you do not have experience with putting together large items. Amazon offers assembly options for most products, or you can hire locally.

Deck Length/Running Surface

The deck length and running surface length are considerations for the user. While smaller users will be able to walk and run on longer deck lengths safely, taller users will struggle to use shorter deck lengths. Make sure that your stride can comfortably fit within the deck range.

Durability & Stability

Curved treadmills offer greater durability and stability compared to traditional treadmills. You will want to look at the materials used, however, to make sure that your curved treadmill is strong and steady.

Price & Warranty

As always, review the overall cost and warranty to get the most value for your money. You can choose higher end or lower end models for your budget, but make sure you have your non-negotiables.

The Assault Fitness AirRunner curved treadmill is an excellent choice for exercisers who want a robust and durable machine that can deliver. This curved treadmill does not have a maximum speed and is entirely manually operated.

As with all curved treadmills, this treadmill won’t impact on the environment and won’t require an outlet plug-in. This treadmill is relatively lightweight at 280 lbs. and comes with portable wheels, which makes it easy to transport around your home. This is perfect for homeowners who want to angle their curved treadmill towards the window or  TV, depending on the day. 

The frame and handrails are made out of steel for superior durability. The slat belt has a strong tread, so you won't have to worry about traction. The secure grip and traction make it ideal for HIIT and sprint workouts. In fact, this curved treadmill's slat belt has been tested up to 150,000 miles.

However, this model is expensive, and users have noted that the screen doesn't offer the highest functionality. The display cannot be customized and often fails to save workouts.

Brad wrote on the Assault Fitness site, “This is the smoothest treadmill I have ever run on, no belt slipping, no motor delay. It really mimics outdoor running.” 

If you want a curved treadmill that has a Bluetooth option and is built on a strong steel frame, then the Assault Fitness AirRunner is the best curved treadmill.

Pros

  • No Maximum Speed, Manual Speed
  • Steel frame and handrails
  • Slat belt tested up to 150,000 miles

The IN10CT Health Runner curved treadmill is manually operated with no minimum or maximum speed for optimal workouts. Ideally suited for HIIT workouts, this curved treadmill lets runners run on the balls of their feet for a more natural running form. The neon yellow trim on the treadmill adds a fun, sporty vibe. Wheels on the front of the treadmill make it easier to move when tilted.

The large clear display provides workout details that can help you train more effectively. This display is in crisp white and black for easy readability, but does not offer syncing capabilities.

Workout details include time, distance, pace, heart rate, and calories burned. The treadmill belt’s large slats don't have the same level of traction compared to some of the other models. However, the unique pulley system helps keep the belt on track. This is an expensive treadmill option, but most curved treadmills are pricier in comparison to standard treadmills.

If you want a curved treadmill with a clear display of workout details, this is a great option. This curved treadmill also has one of the largest weight capacities at 400 lbs. and is an excellent choice for heavier runners. This is the best manual self-powered model. 

Pros

  • Clear display with workout details
  • No minimum or maximum speed
  • Large weight capacity of 400 lbs.

Cons

The SpeedFit Speedboard ProXL curved treadmill is a great option for fitness enthusiasts who want a curved treadmill option that can handle serious weight. This curved treadmill has a weight capacity of 400 lbs when running and 800 lbs when walking.

For users who are heavier and need to lose weight before beginning a running program, this curved treadmill is a great start. We also like the shock-absorbing tread belt system. Built with 56 individual slats that all have a ⅜" thick shock-absorbing cushion, this curved treadmill is comfortable for hard workouts and helps soften the blow to your joints.

The unit’s built-in screen system comes with 5,000 personal workouts designed for the individual user. You take a quick 10-minute fitness test to gain access to a free custom set of 5,000 exercises. The steel frame is sturdy and strong; however, we wish the handles were thicker for a more comfortable grip.

There are wheels on the rear end of the treadmill designed to help you position the treadmill, but this still makes it difficult to move the treadmill as it weighs 256 lbs. The 10-year frame warranty is extensive and reassuring.

If you want a curved treadmill with a high weight capacity limit and an easy-to-read screen with large buttons, the SpeedFit Speedboard ProXL is the ideal choice for you. This is the best tech curved treadmill.

Pros

  • 5,000 personal workouts built into the screen system for users

The TZ-3000C curved treadmill is the best value for your money. It’s the most affordable curved treadmill on the market, but it does come with lower quality build materials as a result. For fitness enthusiasts on a budget, however, this won’t matter.

The ergonomic handle system makes it easy for users of all ages to hold on and steady themselves. The two-way chain transmission makes for a smooth treadmill belt experience. A slight blue line on the side of the treadmill creates a sporty aesthetic.

The double chip resistance system gives users the option to increase the resistance for a harder workout. The motorless treadmill forces users to exercise with a more natural stride while increasing the workout load placed on your glutes and hamstrings. Easily stop yourself by leaning backward or use the pull resistance brake. There is only a warranty on the screen display, but this is due to the low cost of the treadmill itself.

  • Ergonomic handle system makes it easy to hold on to multiple points and feel safe

Regular vs Curved Treadmills

Regular treadmills have been a popular fitness choice for homeowners, but curved treadmills give homeowners a choice when it comes to running indoors. Which model is the best for you and your needs? The curved treadmill is manually operated, which means that you won't need to plug it into an outlet, and you can place it anywhere in your home, unlike electrically powered standard treadmills.

A curved treadmill also places additional stress on the body and requires more effort from the user when running, walking, or sprinting. A curved treadmill will push you to run on the balls of your feet, which is a more natural running style. Curved treadmills also use more muscle groups in the body because of the effort required to move the treadmill belt. Expending more energy means that you will build more muscle and burn more calories.

Curved treadmills are also safer because the tread on curved treadmills has more grip compared to standard treadmills. Curved treadmills also do not have motorized buttons, so the treadmill will move to your momentum and your speed, which can help prevent accidents.


Tips for Curved Treadmill Running

When you begin running on a curved treadmill, it may feel strange. After all, most people are used to running on flat ground outdoors or on flat standard treadmills. When you first start to work out on a curved treadmill, you want to focus on finding your stability. Start with a walk and then gradually begin to run slowly.

You can hold on to the sides for support as you find your center. As you start to speed up, you want to think about keeping your body tall and lean. You want to focus on placing pressure on the balls of your feet and keeping your arms in a relaxed 90-degree position swinging from both sides.

Curved Treadmill Exercise Routines

Walking slowly for five minutes, followed by stretching. Then, alternate in sets of thirty seconds each for twenty minutes between the following intervals: walking, jogging, sprinting. Finish with a cool down.

Weight loss curved treadmill exercise routine: High-intensity interval training is a great way to lose weight. If you want to up the intensity from the beginner routine above, try harder intervals. Spend twenty-five minutes working through the following intervals: 30 seconds walking, 1-minute jogging, 30 seconds sprinting.

Treadmill Care & Maintenance

Taking care of your curved treadmill ensures that it will last longer and stay in good condition. Each curved treadmill brand will have its own set of guidelines for their treadmills. However, these weekly and yearly maintenance tips apply to most curved treadmills.

Every week, you should perform a quick inspection of your treadmill. Check the power cord, and then clean the front display panel as well as the handrail. Every three to six months, vacuum underneath the treadmill and inside the treadmill (remove any cosmetic covers to make this possible).

Make sure that you check the nuts and bolts. If any are loose, tighten them. Then, check the drive belt and replace the belt if you notice any missing teeth. You will also want to use an anti-static spray to spray down the moving belt. Always make sure that you unplug your treadmill and make sure it is turned off before inspections and cleanings.
