Elliptical is a stationary exercise machine used for low-impact cardiovascular exercise. It's designed to simulate stair climbing, walking, or running without causing excessive pressure on the joints, hence it's a popular choice for people who want to get the benefits of cardio exercise without putting strain on their joints. The exercise works multiple muscle groups at the same time, including the legs, glutes, arms, and core, making it a total body workout. Elliptical provides an effective cardiovascular workout that can help you burn calories, lose weight, and improve overall fitness. It can be used for steady-state cardio or high-intensity interval training (HIIT) depending on the individual's fitness goals. The machine comes in different resistance levels, which can be adjusted to match your fitness level and make the exercise more challenging. Additionally, some elliptical machines have built-in heart rate sensors, allowing you to monitor your heart rate and adjust your workout intensity accordingly.
