There are several factors to consider when setting up a physical activity program. These include setting specific, measurable, attainable, realistic and timely goals. It's important to choose activities based on cost, location, health level, available time and place, personal safety, and need for training. An effective program incorporates principles like overload, progression, and specificity. It's also essential to warm up before a workout, engage in an appropriate intensity, duration and type of activity, and cool down afterwards. Progress should be monitored through a fitness journal tracking goals, frequency, intensity, time, and type of activities.
