Intensity

Intensity is the amount of effort and energy you put toward physical activity.
For our purposes, low intensity training means to train with lower resistance. High intensity would be training at a greater resistance.
 
Intensity Level
  0 = No resistance, 0% effort, sitting on the couch
  5 = Medium resistance, 50% effort, some fatigue
10 = Much resistance, 100% effort, near muscle failure
Building muscle requires medium to high intensity ranges. You will need to determine your intensity levels that will correspond to your weight lifting routine.
Training to complete failure using all out effort requires high intensity ranges. Training to failure is required for maximum muscle growth. High intensity effort triggers the body to produce more of the hormones that stimulate muscle recovery and growth.
If you're just starting a workout program, you may want to start somewhere in the intensity level of 3-5 so that you can focus on proper form. After 8 weeks of training you should have increased your intensity level into the 8 - 10 range.
