From the Guidelines

Starting weightlifting in your 40s is crucial for maintaining muscle mass, bone density, and overall health, and it is recommended to begin with 2-3 sessions weekly, focusing on major muscle groups with moderate weights and proper form. According to the 2018 Dutch physical activity guidelines 1, engaging in activities that strengthen muscles and bones at least twice a week is recommended, with older adults benefiting from combining these with balance exercises. Weightlifting can help combat age-related muscle loss (sarcopenia) and increase bone density, reducing fracture risk and helping prevent osteoporosis 1.

The benefits of weightlifting in your 40s include:

  • Improving metabolic health by increasing insulin sensitivity and resting metabolic rate, making weight management easier
  • Increasing growth hormone and testosterone production, which naturally decline with age, helping maintain muscle mass and energy levels while improving mood and cognitive function
  • Enhancing overall quality of life by reducing the risk of chronic diseases, such as cardiovascular disease and type 2 diabetes
  • Improving physical function and mobility, reducing the risk of falls and injuries

For beginners in their 40s, it is essential to:

  • Start with compound exercises like squats, deadlifts, chest presses, and rows
  • Use moderate weights that allow 8-12 repetitions with proper form
  • Gradually increase weight as you progress
  • Ensure 48 hours between training the same muscle groups
  • Prioritize proper warm-ups, cool-downs, and stretching to prevent injuries and promote recovery

Overall, incorporating weightlifting into your routine in your 40s can have a significant impact on your overall health and well-being, and it is recommended to start with a moderate and consistent approach, gradually increasing intensity and frequency as you progress 1.
