The passage lists the Phase 1 (Stabilization Endurance) target as 1–3 sets per exercise, which matches the goal of improving stability and muscular endurance. The other choices do not match the Phase 1 set range shown in the provided phase guidance.

Excessive low-back arching during an overhead squat commonly reflects an anterior pelvic tilt and increased lumbar lordosis. This compensation is most often driven by overactive hip flexors (which pull the pelvis forward) and overactive erector spinae (which increase lumbar extension). The choice mentioning “overactive gluteus maximus and abdominal muscles” would be more consistent with a posterior pelvic tilt (flattening the low back), not excessive arching. The choices describing underactive hip flexors and erector spinae or underactive quadriceps and rectus abdominis do not best match the typical compensation pattern that creates increased lumbar extension in this test.

The best scope-appropriate action is to avoid diagnosing or attributing a symptom to a supplement, document the client’s report, and refer to a qualified healthcare provider for assessment. The choices describing “explaining it is a known side effect,” “advising a dose change,” or “providing a replacement supplement plan” require clinical judgment and individualized supplementation guidance that falls outside a fitness professional’s scope. The choice suggesting to “reassure the client and continue as usual” fails to address a potential health concern and misses an appropriate referral trigger.
