Muscle-Strengthening Activity
  • Intensity, or how much weight or force is used relative to how much a person is able to lift;
  • Frequency, or how often a person does muscle strengthening activity; and.
  • Repetitions, or how many times a person lifts a weight (analogous to duration for aerobic activity).
