Although many of your fellow gym members might favor running on the treadmill, don't feel sheepish that you'd rather spend your workout walking. Walking can not only burn calories, but also lead to stronger muscles and bones, improve your stamina and reduce your anxiety. You can walk for hours every week without it being too much, provided your body isn't indicating you need a rest.
Aim for an Hour Per Day
Depending on their fitness goals, adults should get at least 150 to 300 minutes per week of moderate cardiovascular exercise, such as walking. Topping 150 minutes can help you maintain your weight, while surpassing 300 minutes can lead to weight loss. Provided you wish to reserve two days per week for rest, your daily treadmill workouts should last 30 to 60 minutes, in general. Significantly surpassing this guideline can lead to the symptoms of overtraining, which include sore muscles and lethargy.
