Final answer:
To prevent low-back pain, maintain proper posture, lift correctly using your legs instead of your back, and take preventative measures such as regular exercise, staying hydrated, and eating a balanced diet.
Step-by-step explanation:
To prevent low-back pain, it's crucial to maintain a healthy lifestyle and to protect your back during physical activities. Here are three ways to help prevent this common issue:
Good posture: Maintain proper posture by standing or sitting such that your center of gravity is above your hips. This helps avoid back strain and damage to disks.
Lift properly: Avoid lifting objects with your back. Instead, lift with your legs to reduce the risk of muscle strain and damage to your back's discs and vertebrae.
Preventative measures: Engage in regular exercise, stay hydrated, and eat a balanced diet high in fiber and low in fat to strengthen muscles and maintain overall health.
