Which of the following best describes a suitable program for older adults?

A suitable program for older adults prioritizes safety, functionality, and overall health. Low-impact exercises that focus on balance and strength development are particularly beneficial for this population. These types of exercises can help enhance mobility, reduce the risk of falls, and promote stability, which are crucial factors as individuals age. Strength training is essential for countering muscle loss and improving bone density, while balance exercises can help prevent injuries by enhancing stability.

High-impact aerobics is generally not recommended for older adults, as it can lead to a higher risk of injuries and exacerbate existing joint issues. Marathon training programs tend to place significant physical demands on the body and may not be appropriate for older adults unless they have been progressively trained and cleared by healthcare professionals. Powerlifting classes, while they focus on strength, can involve heavy lifting which may not be suitable for everyone in this age group, especially those who may have pre-existing conditions or are beginners.

Thus, a program centered around low-impact exercises focused on balance and strength provides a well-rounded approach that meets the needs of older adults effectively and safely.
