Health screenings advisable for older adults before starting an exercise program include assessments for cardiovascular health, such as resting heart rate and blood pressure checks. Screening for musculoskeletal issues is critical, as many older adults face joint pain or previous injuries that could affect their ability to exercise safely. Evaluating balance and flexibility can also help prevent injuries. Consulting with healthcare providers for a comprehensive health assessment ensures that older adults can participate in physical activities tailored to their capabilities, maximizing benefits and minimizing risks.
