1) Back pain is very common, affecting over 80% of Americans in their lifetime, and is the second leading reason people see a doctor. Running puts significant force on the back with each foot strike.
2) Maintaining good posture, core strength, flexibility, muscle balance, and ideal body weight can help prevent back pain. Cross-training engages different muscles and tissues.
3) Most back pain can be self-treated with rest, ice, over-the-counter anti-inflammatories, and light activity or core exercises. Seeking medical advice is recommended for severe or prolonged back pain, or pain with other symptoms.
