Is situp exercise not suitable for older people?

Sit-ups can be unsuitable for older individuals, especially those with back or joint issues, as they place strain on the spine and hip flexors. It's important for older adults to focus on exercises that promote core strength without risking injury, such as modified planks or seated exercises. Consulting a healthcare professional or a fitness trainer can help tailor a safe exercise routine. Always prioritize safety and comfort when engaging in physical activity.
