User: Jill, a 60-year-old personal training client, wants to improve her hip flexibility. Jill complains that her low back aches after prolonged sitting. Suggest two ways she could minimize this discomfort.
Assistant: First, it is possible that Jill may have poor posture, which creates muscular fatigue, joint compression, and stresses the discs that cushion her vertebrae. She can focus on having better posture while sitting, keeping her spine straight, hips level, shoulders level, and head erect and straight. She should also balance her weight equally on both feet. If she needs to sit for extended periods of time, she can change her position often; she should periodically walk around and gently perform stretches for her muscles to relieve tension. Secondly, outside of things she could do while sitting, she can consider performing exercises for lower back care. For example, she can perform exercises such as pelvic tilts, trunk flex, partial sit-ups, or even engage in things like yoga or pilates to better strengthen her lower back as well as improve flexibility. Both of these will help reduce her lower back aches.
