Stability of Folding Treadmills Versus Nonfolding

Purchasing a treadmill for home use does not mean compromising on safety. Treadmill shoppers can choose either a folding model that can be stored in your bedroom closet or a nonfolding treadmill to keep wherever you like to exercise. High-quality folding treadmill designs are as stable and safe as their nonfolding counterparts. Determining which option will provide the best stability for you depends on your height and weight, and whether you like to walk, run or jog.

  1. Belt Size

    • The treadmill belt length and width is a critical factor in treadmill stability. Most treadmill belts are 16 to 20 inches wide and 45 to 62 inches in length. An 18-inch width is a minimum for walking, and a 20-inch width is preferable for running. A length of 50 to 54 inches is recommended for walking. If you are a runner, a belt of 58 inches is recommended. Folding treadmill belts tend to be narrower and shorter, making them adequate for walking. Nonfolding treadmill belts provide more stability for runners and taller individuals.

    Motor Size and Horsepower

    • The motor size of your treadmill will determine whether you have a smooth and stable run or walk. If a motor’s continuous duty, or the horsepower displayed during continuous use, is not adequate, neither is the treadmill’s stability. Continuous duty should be 2 mph for walking, 2.5 mph for jogging and 3 mph for running. A weak treadmill motor means decreased continuous capability, or a shorter motor life. Over time, your workouts could get shaky. More expensive treadmills tend to have better motor power, leading to sustained stability with extended use.

    Weight Capacity and Frame Quality

    • Folding and nonfolding treadmills can have similar weight capacities. Determine how much weight the treadmill can withstand before purchase. Most manufacturers overestimate the weight capacity by 30 to 50 pounds, so subtract accordingly for a more accurate reading. Treadmills with inadequate weight capacities can cause the belt, motor and bearings to die prematurely, leading to decreased stability with use. Treadmill frames are made out of plastic or metal. Metal frames offer improved stability, especially when running. Nonfolding treadmills are made out of metal, while the folding option is often made out of plastic.

    Take a Test Drive

    • Read reviews of the folding and nonfolding treadmills you are interested in purchasing and speak to your local gym representative about which models are best, then go for a test drive. Walk, run and jump on the treadmill at different speeds to make sure it does not wobble or shake with movement. Pay close attention to whether the belt is wide enough and long enough for your stride. Verify that the stability of a folding treadmill is not compromised when it is moved or folded.
