Pass the NASM Personal Trainer CPT Questions and answers with ValidTests

NASM’s resistance training technique guidelines emphasize maintaining proper lower extremity alignment to prevent injury and maximize movement efficiency. For squatting patterns—including the ball squat—the knees should track in line with the second toe, ensuring the tibia and femur remain in proper alignment and reducing valgus or varus stresses at the knee. This position also promotes balanced foot loading and optimal activation of the glutes, quadriceps, and hamstrings. The Study Guide warns that deviations such as hip adduction, foot pronation, or internal hip rotation during squatting increase abnormal stress through the kinetic chain, leading to compensatory patterns and potential overuse injuries. Therefore, “knee over second toe” represents the correct, safe position for the lower extremities in a ball squat.

In the Stages of Change Model, NASM defines Preparation as: “The client intends to act in the near future, usually within the next month”. This stage is characterized by having a clear plan and intent to begin behavior change soon, possibly with some minor steps already taken (e.g., buying workout clothes or scheduling sessions). In this scenario, the client is “planning to begin a weekly exercise plan within the next month,” which exactly matches the preparation stage definition.

By contrast, Contemplation is thinking about starting in the next 6 months, Action is actively performing the new behavior (within the last 6 months), and Maintenance is sustaining the behavior for more than 6 months.

In the single-leg squat assessment, inward movement of the knee (valgus collapse) indicates possible overactivity in muscles that internally rotate and abduct the hip, combined with underactivity in muscles that externally rotate and abduct the hip. NASM’s movement assessment guidelines identify the tensor fascia latae (TFL), along with the adductor complex and vastus lateralis, as common overactive contributors to knee valgus. The Study Guide links this compensation to “altered length–tension relationships” where overactive TFL can inhibit the gluteus medius and maximus, leading to poor hip stabilization. The valgus motion increases stress on the knee joint and the kinetic chain above and below it. The corrective strategy involves inhibiting and lengthening the overactive TFL through self-myofascial release and static stretching, while activating the underactive gluteal muscles and integrating functional movement patterns. In contrast, the gluteus medius and maximus are typically underactive in this scenario, and the VMO plays a role in patellar tracking rather than causing knee valgus.
