Treadmills are a type of home gym equipment designed to let you do walking, jogging or running exercises from the comfort of your home. Many treadmills can adjust the intensity of the workout by changing the speed of the belt that you are running/walking on or by changing the incline of the surface that supports the belt. Incline can be used to replicate hills and slopes that you might encounter when exercising outdoors.
Whether you prefer to control speed or incline, both types of treadmill adjustments will help you burn calories and improve your endurance, leg strength and lung strength (aerobic fitness). Whilst increasing the incline and speed will each have different advantages; it is worth remembering that the best workout routines are the ones we enjoy doing.
When you increase the incline or speed on a treadmill, your body will need to burn more calories to keep up the pace. Introducing an incline will help improve muscle strength in your legs, whilst speed improves endurance.
