A friend wants to begin a structured exercise program and has heard that general guidelines exist regarding recommended intensity for various exercise components but does not know what they are. Explain to your friend these intensity guidelines within each area of health-related fitness.
What will be an ideal response?
For aerobic activities, the recommended intensity should be within the target heart rate zone (lower end for moderate-intensity aerobic exercise, higher end for vigorous-intensity aerobic exercise). Resistance exercises for muscular strength and endurance should include enough resistance to cause muscle fatigue after 8-12 repetitions. For stretching exercises to enhance flexibility, target muscles should be stretched to the point of mild tightness without significant discomfort.
