To determine your move goal on an Apple Watch, you can consider various factors such as your activity level, age, weight, job, and exercise habits. The move goal is designed to encourage a more active lifestyle without being discouraging. It should be challenging yet achievable, and it should require at least 15-30 minutes of exercise to achieve. The move goal is calculated based on the active calories burned throughout the day, and it can be set using the Harris-Benedict formula, which takes into account your Basal Metabolic Rate (BMR) and activity level. Some recommendations for the move goal range from 400 to 600 calories per day, but this can vary depending on individual factors such as gender, age, height, weight, and activity level. Ultimately, the move goal should be personalized to your habits, goals, and results, and it should challenge you to stay healthy. Some users set their move goal to 550 or even 600 calories, while others prefer a lower goal that they can reach 90% of the time, as they find it more motivating to achieve their goals regularly. Therefore, the move goal should be tailored to your individual circumstances and preferences, aiming for a balance between challenge and achievability.
