ACSM ACSM Corrective Exercise Specialist 2

Question 1

Which muscle is most commonly overactive and contributing to anterior pelvic tilt?

Accepted Answer

Hip flexors (iliopsoas)

Answer

Tight hip flexors pull the pelvis anteriorly, creating an increased lumbar lordosis and anterior pelvic tilt.

Question 2

When assessing the overhead squat, knees caving inward (valgus) most likely indicates weakness in which muscle group?

Accepted Answer

Hip abductors and external rotators

Answer

Weak hip abductors and external rotators fail to control femoral internal rotation and adduction, causing knee valgus.

Question 3

In the ACSM corrective exercise continuum, which phase involves static and active stretching of overactive muscles?

Accepted Answer

Phase 2 – Lengthen

Answer

The Lengthen phase uses static stretching and neuromuscular stretching to increase flexibility of overactive tissues.

Question 4

A client demonstrates excessive forward trunk lean during an overhead squat. Which underactive muscle pair most likely needs strengthening?

Accepted Answer

Gluteus maximus and thoracic extensors

Answer

Weak gluteus maximus and thoracic extensors prevent the client from maintaining an upright torso during the squat.

Question 5

Which stretching technique involves a 30-second hold and is used in the Lengthen phase of the corrective exercise continuum?

Accepted Answer

Static stretching

Answer

Static stretching with a 30-second hold is the primary technique used in the Lengthen phase to increase muscle flexibility.
