1. how should you hold a heavy object?

close to your body
away from your body
with your arm outstretched in front of you
above your head

Explanation:

• Question 6: The pelvic tilt stretch helps strengthen the core muscles, which support the back and keep it safe from injury. Biceps curl targets the biceps, sit - up targets the abdominal muscles (not a stretch), and push - up targets the chest and triceps.
• Question 7: Spinal stenosis is a condition that affects the spine. Wrist strain, resolved influenza, and sprained ankle are not related to the back in terms of increasing the risk of recurrent back conditions.
• Question 8: Holding a heavy object close to the body reduces the torque on the back muscles. Holding it away from the body, with the arm outstretched, or above the head increases the moment arm and thus the force on the back muscles, increasing the risk of injury.

Answer:

1. Pelvic tilt
2. Spinal stenosis
3. Close to your body
