Client Assessment Protocols: OHSA, FMS, PAR-Q - Step-by-Step Guide
THE PROBLEM: 73% of training injuries could have been avoided through proper initial client assessment. Yet only 34% of personal trainers conduct comprehensive assessments before starting training.
Did you know:
- PAR-Q (Physical Activity Readiness Questionnaire) is the only official pre-screening tool recommended by international fitness organizations?
- FMS (Functional Movement Screen) has reliability ICC 0.81 (excellent), but its validity as injury predictor is controversial?
- Overhead Squat Assessment (OHSA) reveals real-time compensations and weaknesses that can lead to injuries?
This article is a complete guide to client assessment protocols based on NASM, ACE, ACSM 2024 standards, including:
- Step-by-step instructions with checklists
- Result interpretation criteria
- Ready-to-print forms (PDF)
- Video assessment demonstrations
- Safety protocols and contraindications
π What Is Comprehensive Client Assessment and Why Is It Critical?
Definition and Goals
Comprehensive client assessment is a systematic process of collecting information about:
- Health status and medical history
- Physical fitness level
- Movement patterns and posture
- Goals and limitations
3 Key Goals:
- Safety - Identify contraindications to physical exertion
- Personalization - Tailor training program to individual needs
- Progress Tracking - Establish baseline for measuring results
Industry Standards (2024)
According to NASM, ACE, ACSM, each client assessment should include minimum 5 components:
| Component | Tool/Protocol | Time |
|---|---|---|
| 1. Health pre-screening | PAR-Q+, Health History Questionnaire | 10-15 min |
| 2. Posture assessment | Static posture analysis (NASM) | 5-10 min |
| 3. Movement screening | OHSA, FMS, Single-Leg Squat | 15-20 min |
| 4. Performance Testing | VO2 max, 1RM, Body Composition | 20-30 min |
| 5. Goal Setting | SMART Goals, Motivational Interview | 10 min |
Total time: 60-85 minutes for comprehensive initial assessment.

Static posture assessment is observational evaluation of client's body alignment in standing position, used to identify deviations from ideal posture.
Goals:
- Identify muscle imbalances
- Predict potential compensatory patterns during movement
- Plan corrective exercises
NASM Kinetic Chain Checkpoints (KCC)
NASM uses 5 Kinetic Chain Checkpoints to assess posture:
| Checkpoint | Ideal Position | Common Deviations |
|---|---|---|
| 1. Foot & Ankle | Feet pointed straight ahead, neutral arches | Feet turn out/in, flat feet, high arches |
| 2. Knee | Knees pointed straight, neutral alignment | Knock knees (valgus), bow legs (varus) |
| 3. LPHC (Lumbo-Pelvic-Hip Complex) | Neutral pelvis, natural lumbar lordosis | Anterior/posterior pelvic tilt, excessive lordosis |
| 4. Shoulders | Level shoulders, scapulae flat on ribs | Rounded shoulders, elevated shoulders, scapular winging |

What Is OHSA?
Overhead Squat Assessment is first comprehensive look at client movement β dynamic assessment of client's ability to perform squat with arms raised overhead, designed to evaluate:
- Dynamic posture
- Mobility
- Core stability
- Neuromuscular control
OHSA is reliable and valid for repeated trials showing movement impairments.
Source: NASM CPT Chapter 12
Step-by-Step OHSA Protocol
Setup and Instructions
Setup:
- Client stands feet hip-width apart
- Arms raised overhead, elbows straight
- Stick or light dowel rod in hands (optional)
Client instructions:
"Raise your arms overhead and keep them there. Squat as deep as you can while keeping heels on floor and arms overhead. Perform 5 repetitions at controlled tempo."
Observation:
- Anterior View (front): 1-2 repetitions
- Lateral View (side): 1-2 repetitions
Compensations to Observe
ANTERIOR VIEW:
| Checkpoint | Compensation | Possible Overactive Muscles | Possible Underactive Muscles |
|---|---|---|---|
| Feet | Feet turn out | Soleus, lateral gastrocnemius, biceps femoris | Medial gastrocnemius, medial hamstrings, gracilis, popliteus |
| Feet | Feet flatten (pronation) | Peroneals, lateral gastrocnemius, biceps femoris | Posterior tibialis, anterior tibialis, medial gastrocnemius |
| Knees | Knees move inward (valgus) | Adductors, TFL, vastus lateralis, biceps femoris | Gluteus medius/maximus, vastus medialis |
| Knees | Asymmetric knee alignment | Unilateral muscle imbalances | Opposite side imbalances |
LATERAL VIEW:
| Checkpoint | Compensation | Possible Overactive Muscles | Possible Underactive Muscles |
|---|---|---|---|
| LPHC | Low back arches (anterior pelvic tilt) | Hip flexors, erector spinae, latissimus dorsi | Gluteus maximus, hamstrings, intrinsic core stabilizers |
| LPHC | Forward lean (excessive) | Soleus, gastrocnemius, hip flexors, abdominals | Gluteus maximus, erector spinae |
| Shoulders | Arms fall forward | Latissimus dorsi, teres major, pectoralis major/minor | Mid/lower trapezius, rhomboids, rotator cuff |
| Knees | Knees move forward excessively | Hip flexors, gastrocnemius/soleus | Gluteus maximus, hamstrings, intrinsic core |
Source: NASM Chapter 12
OHSA Modifications
If client cannot perform standard OHSA (mobility limitations, lack of control), use modifications:
1. Heels Elevated OHSA:
- Place 1-2 inch riser under heels
- Goal: Reduce ankle dorsiflexion requirements
- Interpretation: If compensations disappear β ankle mobility problem
2. Hands-on-Hips Modification:
- Hands on hips instead of overhead
- Goal: Reduce shoulder mobility and thoracic extension requirements
- Interpretation: If compensations disappear β shoulder/thoracic mobility problem

Rationale: Exhaustive tests at end so they don't affect tests requiring rest/precision.
Source: Exercise.com - Fitness Assessments Guide
VO2 Max Testing
What Is VO2 Max?
VO2 Max = Maximum Volume of Oxygen consumption = gold standard measure of cardiorespiratory fitness.
Unit: ml/kg/min (milliliters oxygen per kilogram body weight per minute)
Field Tests (without lab equipment)
1. Cooper 12-Minute Run Test
Protocol:
- Client runs/walks as far as possible for 12 minutes
- Measure distance in meters
Formula:
VO2 max (ml/kg/min) = (Distance in meters - 504.9) / 44.73Example:
- Distance: 2400 meters
- VO2 max = (2400 - 504.9) / 44.73 = 42.4 ml/kg/min
2. Rockport 1-Mile Walk Test
Protocol:
- Client walks 1 mile (1.6 km) as fast as possible
- Measure time and HR at end
Formula:
VO2 max = 132.853
- (0.0769 Γ weight in pounds)
- (0.3877 Γ age)
+ (6.315 Γ gender [1=M, 0=F])
- (3.2649 Γ time in minutes)
- (0.1565 Γ HR)3. Bruce Treadmill Protocol
Protocol:
- Treadmill, difficulty increases every 3 minutes
- Stage 1: 1.7 mph, 10% grade
- Stage 2: 2.5 mph, 12%
- Stage 3: 3.4 mph, 14%
- Etc., until exhaustion
- Measure time to exhaustion
Formula (for men):
VO2 max = 14.8 - (1.379 Γ time in minutes) + (0.451 Γ timeΒ²) - (0.012 Γ timeΒ³)Source: BodySpec - VO2 Max Guide

Body Composition Assessment
Measurement Methods
1. Skinfold Calipers
Protocol (Jackson-Pollock 3-Site):
Men (chest, abdomen, thigh):
- Chest: diagonal fold between armpit and nipple
- Abdomen: vertical fold 2 cm beside navel
- Thigh: vertical fold mid-front of thigh
Women (triceps, suprailiac, thigh):
- Triceps: vertical fold on back of arm
- Suprailiac: diagonal fold above hip bone
- Thigh: vertical fold mid-front of thigh
Each measurement 3x, average of 3 measurements
Body density formula:
Men:
BD = 1.10938 - (0.0008267 Γ sum of 3 measurements) + (0.0000016 Γ sumΒ²) - (0.0002574 Γ age)
Women:
BD = 1.0994921 - (0.0009929 Γ sum of 3 measurements) + (0.0000023 Γ sumΒ²) - (0.0001392 Γ age)Body Fat % (Siri Formula):
Body Fat % = ((4.95 / BD) - 4.50) Γ 1002. Bioelectrical Impedance Analysis (BIA)
Protocol:
- Client fasted (4-6h without eating/drinking)
- Avoid exercise 12h before test
- Empty bladder before test
- Step on/grip BIA electrodes
BIA sends weak electrical current through body and measures impedance:
- Muscle: high water content = low impedance
- Fat: low water content = high impedance
Accuracy: Β±3-5% error vs DEXA
3. DEXA Scan (Dual-Energy X-ray Absorptiometry)
Gold standard for body composition:
- Precise measurement: Fat mass, Lean mass, Bone density
- Regional analysis (arms, legs, torso)
- Cost: $50-120/scan
4. Circumference Measurements
Protocol:
- Waist: narrowest part, natural state
- Hips: widest part of glutes
- Arms, thighs: mid-segment, muscle relaxed
Waist-to-Hip Ratio (WHR):
WHR = Waist circumference / Hip circumferenceNorms:
- Men: <0.90 = low risk, >1.0 = high risk
- Women: <0.80 = low risk, >0.85 = high risk
Source: Exercise.com - Fitness Assessments
Strength & Endurance Testing
1-RM Estimation (without actual max lift)
Protocol:
- Client performs exercise (squat, bench press, deadlift) with submaximal weight
- Repetitions to failure: 4-10 reps
- Use Epley or Brzycki formula
Epley Formula:
1RM = weight Γ (1 + 0.0333 Γ reps)Example:
- Bench press: 132 lbs Γ 8 reps
- 1RM = 132 Γ (1 + 0.0333 Γ 8) = 132 Γ 1.2664 = 167 lbs
Timed Muscular Endurance Tests
1. Push-Up Test (maximum number in 1 minute)
Norms (number of push-ups):
| Age | Excellent (M) | Good (M) | Excellent (F) | Good (F) |
|---|---|---|---|---|

π― PART 6: Goal Setting & Action Planning
SMART Goals Framework
Specific - Measurable - Achievable - Relevant - Time-bound
Transformation example:
- β Vague: "I want to be fitter"
- β SMART: "I want to increase VO2 max from 38 ml/kg/min (average) to 43 ml/kg/min (good) in 12 weeks through 3x/week cardio training (HIIT + steady-state)"
Motivational Interviewing Techniques
Open questions:
- "Why is this goal important to you?"
- "How will you feel when you achieve it?"
- "What might be challenging?"
Reflective Listening:
- Client: "I want to lose weight but don't have time"
- Trainer: "I understand time is a barrier for you. Tell me, what does a typical day look like?"
Affirmations:
- "I see you're very motivated"
- "That's great you're already thinking about solutions"
π Complete Assessment Process - 60-Minute Session
Assessment Session Timeline
0-10 min: Introduction and PAR-Q/HHQ
- Welcome, rapport building
- Complete PAR-Q (if not done beforehand)
- Review HHQ, red flags identification
10-20 min: Static Posture Assessment
- Views: front, side, back
- Documentation with checklist
20-40 min: Movement Screening (OHSA + 2-3 FMS tests)
- OHSA (with modifications if needed)
- Selected FMS tests based on OHSA findings
- Example: If OHSA shows knee valgus β FMS Single-Leg Squat
40-55 min: Performance Testing (selected tests)
- 1-2 tests based on client goals:
- Goal: Fat loss β Body composition (skinfold/BIA)
- Goal: Endurance β VO2 max estimation (Cooper/Rockport)
- Goal: Strength β 1RM estimation
55-60 min: Goal Setting & Program Overview
- SMART goals with client
- Program outline
- Q&A, next steps
Documentation and Follow-Up
Documents to archive:
- PAR-Q (signed)
- Health History Questionnaire (signed)
- Static posture assessment checklist
- OHSA checklist
- FMS score sheet (if used)
- Performance test results
- SMART goals document
Reassessment schedule:
- 4-6 weeks: Movement screening (OHSA, FMS)
- 8-12 weeks: Performance tests (VO2 max, 1RM, body composition)
- 12 weeks: Complete reassessment (all components)
π¨ Contraindications and Safety Protocols
Absolute Contraindications to Performance Tests
Client should NOT perform exercise tests if:
- Unstable coronary artery disease (unstable angina)
- Uncontrolled cardiac arrhythmias
- Severe aortic stenosis
- Uncontrolled hypertension (>180/110 mmHg)
- Acute myocarditis or pericarditis
- Pulmonary embolism or deep vein thrombosis (last 3 months)
Relative Contraindications
Medical consultation recommended, but light tests possible:
- Moderate aortic stenosis
- Electrolyte abnormalities
- High-risk pregnancy
- Unknown arrhythmias
- Advanced atrioventricular block
Emergency Protocols
Stop test immediately if client experiences:
- Chest pain
- Dizziness, nausea, loss of consciousness
- Irregular or very rapid heartbeat
- Shortness of breath disproportionate to exertion
- Pallor, cold sweat
Action:
- Stop test, seat client
- Monitor vital signs (HR, BP if available)
- If symptoms don't resolve in 5 min β call emergency (911)
π Key Takeaways and Next Steps
5 Most Important Lessons
1. PAR-Q is MANDATORY, not optional
- Only official pre-screening tool
- Legal protection for trainer
- Download from ePARmed-X+: https://eparmedx.com/?page_id=79
2. OHSA > FMS for most trainers
- OHSA: Faster (5 min), reliable, valid for movement disorders
- FMS: Longer (20 min), excellent reliability, but controversial validity as injury predictor
- Recommendation: Start with OHSA, add 2-3 FMS tests if deeper assessment needed
3. Not every client needs every test
- Tailor test battery to client goals:
- Fat loss β Body composition, basic movement screen
- Performance athlete β Full FMS, VO2 max, 1RM
- Senior/rehabilitation β Focus on balance, flexibility, contraindications
4. Reassess every 4-12 weeks
- Movement screening: every 4-6 weeks
- Performance tests: every 8-12 weeks
- Why: Progress tracking = client motivation + data-driven program adjustments
5. Documentation protects you and client
- Signed PAR-Q/HHQ = legal protection
- Assessment checklists = professional standard
- Progress tracking = accountability
Your First Step Today
Mini assessment protocol (20 minutes) to implement starting tomorrow:
- PAR-Q (5 min) - ALWAYS
- OHSA (5 min) - Front + side view
-
1 performance test (10 min) - Choose based on goal:
- Fat loss: Circumferences (waist, hips)
- Strength: Push-up test to failure
- Endurance: 1-mile walk test (Rockport)
Then: Gradually add components (static posture assessment, FMS, VO2 max) as you get comfortable with protocols.
