NASM defines relative flexibility as the phenomenon where the kinetic chain seeks the path of least resistance during movement. This occurs when one joint or muscle is restricted, causing movement to occur at an alternative joint that has more mobility, often leading to compensations. The CPT7 guide explains that this can result from muscle imbalances, poor flexibility, or faulty movement patterns, and it often appears in functional movement assessments as compensatory motions.

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.

During an overhead squat assessment, an excessive anterior pelvic tilt often indicates an overactive/shortened hip flexor complex, erector spinae, and latissimus dorsi. The NASM CPT7 Study Guide explains that altered length–tension relationships occur “when a muscle’s resting length is too short or too long, reducing the amount of force it can produce” and that muscle imbalance around the LPHC can affect posture and movement efficiency.

The latissimus dorsi, in particular, crosses the lumbopelvic region and, when shortened, can increase lumbar extension and anterior pelvic tilt during movements like the overhead squat. This happens because the lats attach to the thoracolumbar fascia and pelvis, pulling the pelvis into an anterior rotation when overactive. NASM’s movement assessment guidelines identify the lats as a common overactive muscle contributing to excessive lumbar extension and anterior tilt in squat patterns.

Conversely, muscles like the transverse abdominis act as stabilizers to resist this tilt, while hamstrings (including biceps femoris) often present as lengthened in this compensation pattern. The piriformis is typically associated with hip external rotation issues, not directly anterior tilt. Therefore, among the listed options, the latissimus dorsi is the key shortened muscle contributing to excessive anterior pelvic tilt in the overhead squat assessment.

The third step in the Stages of Change model is contemplation. NASM describes this stage as when individuals are aware of the benefits of exercise and are thinking about starting, but have not yet committed to taking action. They often weigh pros and cons, and motivation is inconsistent. The sequence is: 1. Precontemplation, 2. Preparation, 3. Contemplation, 4. Action, 5. Maintenance. Correctly identifying the stage allows the trainer to use strategies like motivational interviewing to encourage commitment.
