For beginners, what is the recommended duration of aerobic activity?

1. 30-60 mins/day

2. 20-30 mins/day

3. 60-150 mins/week

4. 40-70 mins/day

The correct answer is: 20-30 mins/day

The recommended duration of aerobic activity for beginners is typically between 20 to 30 minutes per session. This duration is beneficial as it provides a manageable amount of exercise that can lead to health improvements without overwhelming those who are new to physical activity. For beginners, starting with shorter sessions allows them to gradually build their endurance and cardiovascular fitness while minimizing the risk of injury or excessive fatigue. Additionally, this timeframe is supported by guidelines set forth by health organizations that emphasize the importance of establishing a consistent exercise routine. As beginners adapt to their workout regimen, they can gradually increase the duration and intensity of their aerobic activities to further enhance their fitness levels. While options citing durations of 30-60 minutes or longer may be suitable for more experienced individuals or those aiming for specific fitness goals, they might be challenging for beginners who are just starting their fitness journey. Thus, 20 to 30 minutes serves as an optimal starting point to promote sustainability and stimulate positive health changes.
