There are two main types of treadmills: Motorized and Manual. The belt on a motorized, or power treadmill is powered by an electric motor while with a manual treadmill the runner powers the belt with their footsteps. Generally, non-motorized treadmills are much cheaper. You are advised to purchase a motor driven treadmill if possible, unless you are on a very tight budget. To get the full benefit of your workout, motorized treadmills can be set to a constant speed. You can also use the speed and timing settings to calculate calorie loss, etc. Manual treadmills (without motors), speed up and slow down according to the pace set by the runner, meaning it is difficult to receive a steady workout. Non-motorized treadmills also put a great amount of strain on the on the knees and hip joints. If you are serious about your fitness and want to avoid unnecessary knee and joint injury, then a motorized treadmill is the way to go.

The percentage of the slope inclination and and how it can be adjusted is an important factor to consider when buying a treadmill. The inclination of the treadmill deck plays an essential part in the burning of calories and the length of endurance. There are three main types; manual adjustment, button or console controlled and automatic. Manual adjustment is at the bottom end of the scale, requiring you to stop your exercise to do so. Button or console controlled means you can change the slope gradient at the touch of a button without interrupting your routine. The automatic adjustment is the best option which often comes in conjunction with a heart rate monitor or programmable fitness routines.

Bear in mind when selecting a treadmill that runners and obese users will put a heavier load on the machine. Be sure the motor has at least 1.5 horsepower.

Fitness equipment like treadmills can take up quite a bit of space in a room. The average size of a treadmill is around 3' wide by 7' long so expect to devote a large portion of your room to it. However, if you are lacking in space, perhaps consider a collapsible treadmill instead. These space saving treadmills are designed to be folded up and stored away easily. They usually come on runners for easy maneuvering purposes. Generally, folding treadmills can be bought at a much cheaper price as well.

Why not, if it is nice weather! However, we do not recommend you to use it outdoors in humid weather or to get sand on it, which could damage the mechanism.

Treadmills offer ideal cardiovascular workout routines. FitMill comes with wireless fitness bands which can be programmed to keep your heart rate at a specific level by adjusting the speed, intensity and incline of your workout.
