Q: My hips get tight and my legs jerk when I walk and carry heavy objects (25-30 lbs). What is causing this and how do I fix this?
When you carry heavy objects, you feel tightness in the hips and your legs jerk. Also when you carry things, you make use of the muscles along your spine to keep them straight, but if they are too heavy, you hyperextend the back, causing your pelvis to shift forward, thus causing your hip flexors to contract too. What I would suggest you'd do is to:
- Stretch your hip flexors before doing the task
- Take frequent breaks every 5-10 minutes, or just before the muscles start to feel tight
- Make sure your back is erect, but not hyperextended
- Draw-in your abdominals and inhale before you lift the object.
- Exhale while you are lifting.
- Hold to object close to midline of your body
