Intensity may be the most important aspect of the FITT principle. Engaging in a “cardio” program that does not stress the CR system to the recommended levels will be ineffective. Engaging in a program that overstresses the system can lead to injury and pose unnecessary risks. To measure weightlifting intensity medically, one only needs to measure their heart rate at the end of an individual session. Like a load-based measurement, a medical measurement is based on the heart rate as the percentage of maximum heart rate. You can determine your maximum heart rate by subtracting your age from the number 220.
