Age-related muscle degeneration significantly influences fitness strategies, as older adults often experience sarcopenia, the gradual loss of muscle mass and strength. To combat this, fitness plans should focus on consistent resistance training to promote muscle retention and growth, along with proper nutrition rich in protein to support muscle health. Additionally, integrating balance and flexibility exercises can enhance functional mobility and reduce the risk of falls. Tailoring fitness strategies to accommodate these changes is crucial for maintaining overall health and quality of life.
