What is the recommended total duration per day for older adults, including bout length?

• A. 60-90 minutes per day in 20-30 minute bouts
• B. 30-60 minutes per day, 8-10 minute bouts
• C. 15-30 minutes per day, continuous
• D. 45-60 minutes per day, single session only

Answer: (B)

Older adults benefit from spreading activity through the day, aiming for about 30–60 minutes of moderate-intensity activity daily and using short bouts of roughly 8–10 minutes to reach that total. This approach fits real-world routines, supports safety and sustainability, and still meets the weekly goal of about 150 minutes. Breaking activity into shorter sessions helps when endurance is lower or joints are sensitive, making it easier to start and maintain the habit. Longer single sessions or limiting activity to one continuous block isn’t necessary and can be less practical for many older adults, while underestimating total daily time or insisting on a continuous block may reduce adherence.
