When starting an aerobic exercise program for a relatively healthy older adult, what is the recommended initial stage of progression?

Commencing an aerobic exercise program for relatively healthy older adults should prioritize safety, gradual progression, and adaptability to individual fitness levels. The correct choice emphasizes moderate intensity—defined as 40-60% of maximum heart rate—which is an appropriate starting point for older adults.

This intensity is beneficial because it is generally achievable and fosters cardiovascular benefits without placing excessive strain on the body, reducing the risk of injury or adverse effects. Maintaining this level of activity for about 15-30 minutes allows individuals to build endurance gradually while also offering a reasonable time commitment for those new to exercise.

Initiating an exercise program with such a moderate approach aligns with current guidelines and research that advocate for starting at an intensity that enhances aerobic capacity while considering the potential limitations older adults may face, such as chronic health conditions or lower baseline fitness levels. From this foundation, progress can be made safely, either by increasing duration or gradually increasing intensity as the individual becomes more conditioned.
