A treadmill is an exercise machine that simulates walking or running on a flat surface, usually indoors. It allows you to get in shape and stay motivated with regular exercise. Treadmills are often used for cardiovascular health, weight loss, and general fitness training. They can also help improve your balance, agility, and coordination. Additionally, they can provide relief from joint pain and reduce stress levels.
