There are several methods and devices that you can use to monitor your progress. The first is a weight training log. By entering the exercises that you perform, as well as the number of sets, weight and repetitions that you perform per exercise, you will be able to evaluate whether you are increasing your strength level for each muscle group. Other forms of measuring devices include the tape measure and body weight scale. Use the tape measure to measure your chest, neck, back, upper arms, forearms, waist, hips, thighs and calves. If your goal is to increase muscle size and density, then you should expect to see increases in your measurements.
