When lifting a heavy box from the ground, which technique demonstrates correct biomechanical principles?

  1. Keeping legs straight and bending at the waist
  2. Lifting with a narrow foot stance
  3. Bending at the hips with a straight back
  4. Using primarily arm muscles to lift

\(C\)

Show Worked Solution
  • C is correct: This technique protects the spine while allowing leg muscles to generate force, demonstrating proper application of biomechanical principles for safe and efficient lifting.

Other options:

  • A is incorrect: Keeping legs straight and bending at the waist places excessive stress on the lower back.
  • B is incorrect: A narrow foot stance reduces the base of support, compromising balance and stability.
  • D is incorrect: Using primarily arm muscles ignores the body’s strongest muscle groups (legs and core), leading to inefficient lifting.
