Muscle mass and strength can gradually decline with age, particularly when physical activity decreases. Reduced movement can create a cycle in which muscle weakness makes activity more difficult, leading to further loss of strength and mobility.

Inadequate protein intake may also contribute to difficulty maintaining muscle mass, although individual protein needs vary depending on age, body size, activity level, kidney function, and other health factors.

What may help:

• Stay physically active within your abilities and medical recommendations.
• Include strength and balance exercises when appropriate.
• Discuss an appropriate activity plan with a healthcare professional or qualified fitness professional.
• Include protein-rich foods such as yogurt, eggs, fish, poultry, beans, lentils, and other suitable options.
• If appetite or dietary intake is low, ask a healthcare professional or registered dietitian whether nutritional support is appropriate.

Regular movement and adequate nutrition can help support muscle strength, but there is no single approach that works for everyone.

Understanding the possible cause of leg weakness is important, because the safest next step depends on whether the problem involves muscles, nerves, circulation, nutrition, medication, or another medical condition.
