Candidates have 90 minutes to complete the exam, and the exam follows an open-book format, permitting reference to study materials during testing. A minimum score of 70% is required to pass. Three exam attempts are included with course enrollment; additional retakes can be purchased through NASM Member Services. Candidates have 365 days from their purchase date to study and complete the exam, providing ample time to prepare. The exam does not expire upon passing—credentials are valid indefinitely.

Skills Measured

1.Applied Anatomy and Physiology: Understanding of musculoskeletal anatomy, neuromuscular physiology, and how flexibility and mobility relate to movement mechanics and injury risk.
2.Assessment and Evaluation: Ability to assess client flexibility restrictions, movement patterns, postural deviations, and mobility limitations to inform program design.
3.Stretching and Flexibility Techniques: Proficiency in static, dynamic, PNF, and self-myofascial release methods; selection of techniques appropriate for client goals and contraindications.
4.Program Design: Competency in designing, progressing, and integrating evidence-based flexibility programs tailored to client needs, goals, and fitness levels.
5.Client Communication and Education: Skill in explaining flexibility concepts, managing expectations, and motivating client adherence to mobility work.
6.Special Populations: Knowledge of flexibility training modifications for older adults, injured clients, athletes, and clients with specific health conditions or limitations.

Study Tips

Leverage NASM's course materials and videos systematically; the open-book exam format rewards thorough knowledge of official content and resource location skills.
Study the functional anatomy of major joints and muscle groups in depth—the exam heavily emphasizes how anatomy drives stretching technique selection.
Practice matching client assessment findings (restricted hip ROM, tight hip flexors, etc.) to appropriate stretching progressions and program designs; the exam tests this decision-making.
Review the science behind different stretching modalities (static vs. dynamic vs. PNF) and their evidence-based applications—understand the 'why,' not just the 'what.'
Take advantage of all three included exam attempts; use the first attempt to identify weak content areas, then target those topics before retaking.
Familiarize yourself with real-world client scenarios: take detailed practice notes on how to assess common restrictions and design programs for aging, post-injury, and athletic populations.
Join NASM's online communities or study groups to discuss concepts and hear how other candidates approach flexibility assessment and program design.

Preview — answers shown

1. A potential client mentions during screening that they have advanced osteoporosis and are currently managing acute lumbar radiculopathy. Which professional action is most appropriate before designing a flexibility program?

ADesign a standard stretching program with slightly reduced intensity to account for the conditions

BRefer the client back to their physician for clearance specific to flexibility training before program initiation

CRecommend they return when the radiculopathy resolves and reassess at that time

DProceed immediately with static stretching to address the underlying tightness

Explanation

Multiple serious conditions (osteoporosis and active radiculopathy) create complexity that requires physician input before flexibility training begins. The coach must recognize the limits of their scope and obtain professional medical clearance to ensure safe programming decisions. This protects both client safety and the coach's professional liability and credibility.

2. A coach identifies that a client displays right hip internal rotation limitation and concurrent left hip external rotation limitation. What muscular imbalance pattern does this suggest?

ASymmetrical hamstring tightness affecting both legs

BRight-sided hip external rotator tightness and left hip internal rotator tightness

CGluteus maximus shortening on the left side only

DIliopsoas dominance affecting both lower extremities equally

Explanation

Reduced internal rotation on one side typically indicates external rotator tightness, while reduced external rotation on the opposite side suggests internal rotator muscle tightness. This pattern indicates muscular imbalance across the lower extremity requiring targeted flexibility intervention.

3. A flexibility coach is designing a program for a client recovering from shoulder injury. The client has good passive ROM but struggles with active ROM and stability during overhead movements. Which programming approach best addresses this client's need?

AFocus exclusively on static stretching to improve baseline ROM capacity

BIntegrate mobility work that combines flexibility, strength, and motor control through active and dynamic movements

CAvoid any stretching until strength improves

DUse only contract-relax PNF techniques to maximize passive ROM

Explanation

The distinction between flexibility, which is passive ROM, and mobility, which is active ROM with stability and motor control, is critical. This client's limitation is not passive ROM but rather the ability to actively control and stabilize through that range. Mobility programming integrates stretching with strengthening, proprioception, and neural control through dynamic, functional patterns.

4. During hip flexion ROM assessment, a client demonstrates 100 degrees on the left side and 85 degrees on the right side. After ruling out acute injury, what is the most appropriate next step for the coach?

AImmediately refer the client to a physician for imaging

BConclude the right hip is structurally damaged and avoid any stretching on that side

CUse this baseline data and reassess after 4 weeks of targeted flexibility work on the right

DPerform a postural assessment to check for pelvic tilt and other compensatory patterns

Explanation

A 15-degree asymmetry warrants investigation into postural imbalances, muscle asymmetries, or movement patterns that may explain the ROM difference. Postural assessment helps identify whether pelvic tilt, spinal curvature, or muscular imbalances are contributing to the asymmetry, guiding appropriate program design.

5. A 68-year-old client reports declining flexibility and increased stiffness in the morning. Which age-related factor most directly contributes to this presentation?

ADecreased muscle fiber size

BReduced collagen elasticity and increased connective tissue stiffness

CComplete loss of muscle spindle function

DInability to produce ATP

Explanation

Aging causes increased cross-linking of collagen, reduced water content in connective tissue, and decreased elastin elasticity, resulting in reduced tissue extensibility and the characteristic morning stiffness common in older adults.
