What does “intensity” refer to?
Intensity is basically how hard you are working in a given set. The best way of defining intensity level is by expressing it as a percentage of an individual’s one rep max (that is, the most the person can lift for one repetition only). So we see that intensity is also related to the load on the bar. The heavier the load, the closer to the person’s 1RM, and subsequently, the higher the intensity. Volume is inversely related to intensity, in other words, as volume goes up intensity must go down. A: Intensity in regards to aerobic training means the relative percentage of your maximum heart rate (Beats Per Minute) that you train at. Your maximum heart rate is calculated by subtracting your age from 220. Therefore a 40 year old trainee would have an estimated maximum heart rate of 180. Low intensity refers to training at appx. 60% of this number, or in the above example about 110 BPM, high intensity would be at 85% or about 155 BPM. The big issue is the combination of intensity and durati
