A 48-inch belt will suffice for walkers, but if you want to run faster than a jog, a 54-inch belt will be preferable. Go even longer if you're taller than 6 feet or have an inseam of at least 32 inches.
The best running belts are made of leather or nylon and can be found online and in specialty sports stores. Before you buy a new belt, make sure it's comfortable enough for you. You should be able to fit two fingers between the buckle and your body when standing with your arms by your side. The belt should not cut into your skin anywhere. If it does, you need another one.
You will need a belt with some degree of flexibility to fit properly. Otherwise, it will cause problems when you run. Leather belts tend to be more flexible than their nylon counterparts, so if you plan to run frequently, consider buying several pairs of different sizes.
The best place to attach a belt is below the hip bones, but it can also be used as a cross-training tool to work other muscles such as the chest, back, and abdomen.
Running with no belt at all can be dangerous because you cannot push yourself hard enough to benefit from its effect. However, without a belt, your pants would ride up, showing your underwear which could be uncomfortable and distracting.
Anything less than 16 inches wide is difficult to walk on and dangerous to sprint on. An 18-inch belt is ideal for strolling, while a 20-inch (or bigger) belt is preferable for runners.
The best treadmills are those that fit your needs. If you're looking for something to get in shape, then consider one of the many treadmill kits on the market. These usually include a base model with a comfortable seated position and an adjustable stride length. If you want to go beyond simple walking or running, then look into a premium package deal, which often includes features such as a built-in display, a heart rate monitor, and other accessories.
20 inches is quite a bit of space, but if you need more room, several models offer two side by side. Others have three belts instead of two for increased capacity. In any case, make sure you buy a treadmill that fits your needs now and in the future. A quality unit will last for years if taken care of properly.
So, is 20 inches wide enough for a treadmill? Yes, it can be used for walking or running. However, if you want to be able to stroll as well as run, then choose a model with a wider belt.
The length of treadmill belts varies depending on whether the model is intended for walkers, joggers, or runners. Walkers choose a shorter belt length, whereas runners like to lengthen out their stride. ProForm decks are available in sizes ranging from 55 to 62 inches, making them suitable for all athletes.
The size of the belt is one of the most important decisions you'll make when buying a home treadmill. Understanding how long a belt should be will help you select the right size for your needs and your budget.
Belt length is measured from the center point where it attaches to the motor shaft to the end where it loops over the roller at the back of the machine. So, if you need more distance between those two points, get a longer belt. If you want to go faster, use a shorter belt. The recommended minimum belt length for running is 56 inches, but many experts recommend at least 60 inches for best results.
The ideal treadmill belt length allows for a comfortable stride while keeping the user ahead of the belt. Too short a belt will cause the feet to strike the ground before the treadmill has moved enough for another step. This can be uncomfortable and possibly lead to injury. A belt that is too long may cause the user to take longer steps than normal, which could lead to ankle strain or other injuries.
