NASM’s plyometric training progressions and regressions are based on the force and stability demands of an exercise. A box jump-up with stabilization requires explosive concentric force to jump vertically onto a platform, followed by an isometric hold. A box jump-down with stabilization removes the explosive vertical propulsion requirement and instead focuses on eccentric force absorption and landing mechanics, which generally reduces intensity.

Horizontal jumps, squat jumps, and transverse jumps with stabilization typically demand more power output or multi-planar coordination than a controlled step/landing from a box. Thus, among the listed choices, the box jump-down with stabilization is the regression because it lowers concentric demand while still training landing control and joint stabilization—making it safer for clients not yet ready for the more intense jump-up variations.

When conducting a fitness assessment—especially for older adults—NASM stresses the importance of gathering subjective information regarding the client’s medical history, chronic conditions, medications, and lifestyle factors. The NASM CPT7 Study Guide notes that subjective information “is gathered from the client, including health, medical, and lifestyle history” and is critical for risk stratification and tailoring safe exercise programs.

For older adults, this becomes even more important because the prevalence of conditions like cardiovascular disease, type 2 diabetes, arthritis, and osteoporosis increases with age. Knowing these details allows the CPT to adjust exercise intensity, movement selection, and monitoring protocols.

While body fat percentage, BMI, and postural alignment are valuable metrics, they are forms of objective information obtained through testing and observation—not subjective. Subjective health history is the first step in NASM’s assessment process, ensuring safety and compliance with medical clearance when needed. Therefore, for an older adult, identifying chronic medical conditions during the subjective intake is essential before moving to any performance or body composition assessments.

NASM’s scope of practice clearly states that Certified Personal Trainers are not qualified to prescribe specific meal plans unless they hold an additional, recognized nutrition credential and are legally permitted in their jurisdiction.

While CPTs can provide general nutrition guidelines based on public resources (e.g., USDA MyPlate), creating individualized meal plans is outside their professional scope and constitutes a violation of the NASM code of professional conduct.

This is not a HIPAA violation (Option C), as HIPAA relates to handling of private medical data. It is also not fulfilling a duty within the OPT model (Option D) because nutrition planning is not part of OPT without proper credentialing. Therefore, developing a meal plan for a client as a CPT without proper credentials is a code of conduct violation.

Davis’s law is a principle in human movement science that explains how soft tissue adapts structurally to the stresses placed upon it. NASM describes it as “soft tissue will model along the lines of stress,” meaning that muscles, tendons, and fascia will align and reorganize based on the direction and type of physical forces they experience. This is important in corrective exercise because chronic poor posture, repetitive movements, or imbalances can cause soft tissue to remodel in a way that reinforces dysfunction. For example, if a muscle remains shortened for prolonged periods, collagen fibers may lay down in shortened patterns, limiting flexibility and altering joint mechanics. The other answer options describe different principles: poor neuromuscular efficiency (effect of chronic shortening), altered reciprocal inhibition (C), and the path of least resistance concept in movement compensation (D).

For hypertrophy (muscle growth), NASM’s OPT model prescribes a training intensity of 75% to 85% of the one-repetition maximum (1RM), typically performed for 6–12 repetitions per set with moderate rest intervals (0–60 seconds). This intensity zone maximizes mechanical tension and metabolic stress—two primary drivers of muscle hypertrophy. Lower intensities (10–70%) focus more on endurance or adaptation phases, while higher intensities (85–100%) target maximal strength and power. The 75–85% range balances sufficient load to stimulate growth while allowing for enough volume to create an anabolic environment in the muscle tissue.
