Step-by-step explanation:
Based on the information provided, it would be recommended for your new, 54-year-old male client who weighs 250 lbs and has 25% body fat to start with low-impact activities like walking or swimming to initiate weight loss through aerobic activity.
Low-impact activities are easier on the joints and can help the client gradually increase their physical activity level. Walking or swimming for at least 30 minutes a day, five days a week, can contribute to weight loss and overall health improvement.
As the client progresses and becomes more comfortable with exercise, they can consider adding elements of high-intensity interval training or weightlifting, but it is important to start with lower intensity aerobic activities to avoid injury and ensure a sustainable exercise routine.
