¿Qué significa estar en forma?

Fitness is a combination of factors like cardiovascular health, muscle power, endurance, flexibility, and body composition. Key indicators include BMI, resting heart rate, and blood pressure. While BMI measures weight relative to height, it doesn't differentiate between fat and muscle. Resting heart rate is lower in fitter individuals, and high blood pressure indicates heart strain. Improving fitness involves a healthy diet and regular exercise, which lowers blood pressure, maintains healthy bones, and reduces disease risk. Aerobic exercises are particularly beneficial, and rest is crucial to avoid exhaustion.
