A treadmill lets people achieve a calorie-burning aerobic workout in a protected environment. Running, jogging or walking at a brisk pace for 20 or more minutes raises heart rates, providing aerobic activity that increases heart health. Treadmill workouts increase endurance and help individuals lose weight.
A treadmill provides an even, forgiving surface, reducing the chance of falls during a run or walk. A forgiving surface lessens the impact on joints, encouraging exercise and reducing fatigue and injury. Treadmills with electronic readouts let individuals monitor progress of runs, and some treadmills include pulse readers that let individuals keep track of heart rates for the most healthy workout possible.
