Elliptical vs Treadmill 

Elliptical machines are generally better for joint health compared to treadmills because they provide a low-impact workout. The smooth, gliding motion of an elliptical minimizes stress on knees, hips, and ankles by keeping feet in constant contact with the pedals, avoiding the jarring impact of treadmill running or walking. 

Ellipticals allow for customization that can further reduce joint strain, engage both upper and lower body muscles, and are often recommended for joint injury recovery or chronic conditions. However, the best choice depends on individual health needs, goals, and preferences.
