How do you know your fitness routine is paying off? Track your numbers: 1.Record your pulse rate before and after a brisk 10-minute walk. 2. Record your time after a 1.5-mile run. 3. Count how many pushups you can do at a time and how many situps you can do in one minute. 4. See how far you can reach forward while seated on the floor with your legs in front of you. 5. Measure your waist circumference just above your hipbones. 6. Calculate your body mass index. Repeat these measurements again in six weeks to assess your progress.
