I am a 43-year-old woman weighing 190 pounds. I recently started working out, starting with cardio, walking about 3.5 mph. How long a workout should I be doing? Currently it is one hour.

An hour is a good amount of time for your workouts. The important part of exercise is making progress. Track the number of calories burned during your first few workouts (the treadmill will typically have this information if you enter your weight). Use this information to make small increases each day or each week that you’re exercising.

If you burn 400 calories during your first hour of cardio, try increasing either the speed of your walk or the incline of the treadmill so your burn just a few more (10-25 calories) than you did initially. This will keep your workouts challenging and keep your body from hitting a plateau.
