An elliptical is a type of exercise machine designed to simulate walking, running, or climbing without putting excessive stress on the joints. It features two foot pedals that move in an elliptical motion, allowing users to engage in a low-impact cardiovascular workout. Many ellipticals also come with handlebars for an upper body workout, making them versatile for full-body exercise. These machines often include various settings to adjust resistance and incline, catering to different fitness levels. Users can track their progress through built-in monitors that display metrics like time, distance, and calories burned. Popular in gyms and homes, ellipticals are favored for their efficiency and ease of use.
