BMI, or Body Mass Index, is a measure used to determine if someone is at a healthy weight based on their height and weight. For women, a BMI between 18.5 and 24.9 is typically considered a healthy range. It's important to remember that BMI doesn't account for muscle mass or distribution of fat. How do you feel about your current understanding of BMI? Are there specific aspects you're curious about in terms of health and fitness?
