Treadmills can be classified into two basic types: mechanical and motorized. Each type has its own advantages and disadvantages, but you should put in more effort to a workout with a motorized treadmill, especially if you've never tried one before.
A motorized treadmill is essentially a piece of equipment that operates without the use of a human. It is powered by a belt that is controlled by a computer. Most modern motorized treadmills include a foot pedal, which allows you to make certain activities easier or harder. The standard, straight-arm motor-driven treadmill is an older subcategory of motorized treadmill models.
Electric treadmills are similar in some ways to those that run on electric motors. Some differences are that they have a computer that calculates your workout routines so that you don't have to physically do them, and they are generally less expensive than their manual counterparts. There are a few disadvantages to these, however, as they require a plug-in cord for charging and they don't provide nearly the same workout benefits as a motorized treadmill.
If you have always wanted to try an electric treadmill but you haven't had any luck finding one at an affordable price, consider buying an electric model. While they aren't nearly as portable or convenient as a motorized treadmill, they have one major disadvantage: they are not as efficient as their motorized cousins. A standard treadmill will give you a steady level of resistance that lets you keep up with your fitness routine, and an electric treadmill won't be able to do this as well. This is where an electric motor comes in handy.
The disadvantages of a motorized treadmill are more obvious if you regularly exercise on it. A standard motorized treadmill is generally much heavier and will be very uncomfortable for someone who is used to walking. Because the belt moves on an incline, the treadmill also requires more space to move around, taking up more room in your home or apartment. An electric model that runs on electricity is much lighter and only requires a small amount of space.
The advantages of both motorized and electric treadmills are obvious, but you need to weigh these factors before you decide which one you want to buy. If you're just looking for an extra workout machine, a motorized treadmill might be a good fit. If you are going to use the treadmill for regular gym use or at home, you might want to consider buying an electric model to get the best possible workout.
