Sedentary Lifestyle: Lack of physical activity leads to reduced muscle mass and strength over time.
Aging: Muscle mass naturally declines with age, making it harder to maintain tone and strength.
Nutritional Deficiencies: Inadequate protein or vitamin intake can weaken muscle structure.
Injury or Illness: Conditions such as muscle atrophy or prolonged inactivity can result in weakened muscles.
Hormonal Changes: Reduced hormone levels, such as testosterone, can affect muscle growth and repair.
