Swedish Study Finds Fitness and Strength Decline Begins Around Age 35

A Swedish study conducted over 47 years by Karolinska Institutet tracked fitness, strength, and muscle endurance in adults aged 16 to 63. It found physical performance begins to decline around age 35 and gradually worsens with age. However, the study highlights that starting exercise later in life can still improve physical capacity by up to 10%, emphasizing the ongoing benefits of physical activity at any age.
