Final answer:
Jack should aim to exercise for at least 30 minutes on most days of the week, starting with shorter durations and increasing them over time. Consistency and finding enjoyable activities are crucial for making exercise a habit, and adhering to the HHS recommendations can offer significant health benefits.
Step-by-step explanation:
If Jack wants to get the benefits of exercise, he should aim to engage in at least 30 minutes of physical activity on most days of the week. Beginning with shorter durations such as 10 to 15 minutes a day and gradually increasing to longer sessions can help Jack establish a sustainable exercise routine. Regular jogging will help him maintain cardiovascular health, manage weight, and improve mental well-being. To make exercise a habit, Jack should incorporate it into his daily routine, perhaps by jogging during breaks or choosing to jog instead of using other modes of transportation for short distances. It's important to start with manageable expectations and not to be deterred by perceived barriers such as lack of time or fatigue. As Jack continues to exercise, he can expect to experience not only physical benefits but also improvements in mental health, such as reduced stress and improved self-esteem.
Moreover, while aiming to meet the recommendations of the U.S. Department of Health and Human Services (HHS), which suggests 2.5 hours of moderate-intensity aerobic physical activity per week, Jack can break this down into more manageable sessions spread throughout the week. This can include a combination of jogging and other activities he enjoys, which will help him stay motivated and committed to his exercise routine. Consistency and enjoyment are key factors for maintaining a regular exercise regimen.
