Rate of Perceived Exertion

Aerobic fitness conditioning is improved ONLY IF you increase your exertion during the aerobic walk/run/bike.  Eaxh day estimate how hard you feel your exercise workload is.  This feeling should reflect your total amount of exertion and fatigue, combining all sensations and inner feeelings of physical stress, effort and fatigue. Focus on the entire body.  Try not to underestimate or overestimate your feeling or exertion. Be as accurate as you can.

The RPE Scale gives a quantitative identification of the feeling of fatigue.
It indicates a subjective sensation of effort. These feelings of fatigue are very highly correlated with heart rate,                                                  
                                                           RPE SCALE:

 

6
7 very, very light exertion
8
9 very light exertion
10
11 fairly light exertion
12
13 somewhat hard exertion
14
15 hard exertion
16

17 very hard exertion
18
19 very, very hard exertion
20

 
Training zone is 12-16 on the scale. You must be working at this level to be receiving cardiorespiratory benefit from the exercise. This intensity approximates an intensity of 60-80% of the Target Heart Rate Range using the Heart Rate Reserve method discussed in another fitness article.
