10.6 Exercise Selection, Contraindications, and Referral
Key Takeaways
- Exercise selection follows assessment results, goals, fitness level, medical restrictions, contraindications, and current movement quality.
- Contraindications may be absolute or specific to a position, load, range, intensity, or modality rather than a blanket no-exercise rule.
- Absolute stop signals (chest pain, fainting, severe dyspnea, neurological symptoms, radiating pain) require stopping and following emergency/referral procedures.
- Referral is required for diagnosis, treatment, medical nutrition therapy, psychological counseling, and any service outside the CPT scope of practice.
Choosing, Avoiding, and Referring
Exercise selection is a decision tree. The trainer starts with the client's goal, assessment, fitness level, movement quality, environment, equipment, medical history, and any provider restrictions, then asks: can this exercise be performed safely today? If not, the options are modify, substitute, regress, stop, or refer. NASM CPT7's blueprint names exercise selection based on assessment results, goals, fitness level, and contraindications, alongside special populations and referral indicators — meaning the exam can test exercise choice and scope in a single scenario.
| Finding | Exercise-selection response | Referral trigger |
|---|---|---|
| Knee valgus in squat | Reduce load, cue alignment, strengthen glutes, change stance/variation | Pain, swelling, instability, or unresolved symptoms |
| Limited shoulder mobility | Use landmine, incline, cable, or front-loaded options | Numbness, radiating pain, or a medical restriction |
| Pregnancy after 12 weeks | Avoid prone/supine, reduce impact, monitor symptoms | Bleeding, dizziness, severe pain, provider restriction |
| Hypertension | Avoid Valsalva and heavy straining; gradual intensity | Chest pain, severe headache, faintness, BP >200/110 |
| Diabetes with foot symptoms | Low-impact; inspect footwear and surfaces | Wound, numbness, infection concern, glucose questions |
| Older adult fall risk | Supported balance, stable resistance | Recent unexplained falls or dizziness |
Contraindications, Stop Signals, and Scope
A contraindication rarely means "no exercise at all." More often it means no specific position, load, intensity, range, or modality until cleared. A client with controlled hypertension can train, but heavy breath-holding and maximal lifts may be inappropriate; a prenatal client past 12 weeks can train, but prone and supine positions are avoided. This is the difference between a relative contraindication (modify around it) and an absolute one (do not perform).
Absolute stop signals are categorically different: chest pain, fainting, severe or unusual shortness of breath, sudden neurological symptoms, radiating pain, uncontrolled bleeding, sudden loss of balance, or a client becoming unresponsive require stopping and following emergency or referral procedures. The trainer must not respond with a stretch, a diagnosis, or a motivational speech as the primary action.
Referral also applies to services outside CPT scope. NASM scope language is explicit: personal trainers design safe exercise programs, provide general nutrition and lifestyle suggestions, respond to emergencies, and refer when appropriate. They do not diagnose or treat pain or disease, prescribe medical nutrition therapy or specific meal plans, provide psychological counseling, or adjust medication. Crossing any of those lines is scope creep.
Communicating, Documenting, and Substituting
" That avoids diagnosing while making the safety rationale clear. Written clearance should be specific enough to guide training — "exercise is okay" may not answer whether loaded flexion, intervals, overhead pressing, or impact is permitted; if restrictions are vague and risk is meaningful, ask the client to get clarification from the provider. When coordinating with a client's care team, obtain written consent before sharing personal health information, and document the referral, the client's response, and any restrictions received.
Good substitutions keep the training goal while removing the risk. If a client cannot safely reach the floor for push-ups, use an elevated push-up or cable press. If balance fails during reverse lunges, use supported split squats or step-ups. If a modality is contraindicated, replace the training effect with a safer tool.
Exam traps use confident but unsafe answers: diagnose the injury, prescribe a medication change, ignore chest pain, force a standard assessment, or write a medical diet. The final, practical rule: modify the variables you are qualified to control, and refer the variables you are not qualified to interpret. That boundary is one of the most important professional skills a NASM-CPT candidate must demonstrate.
Building the Referral Network and Recognizing Red Flags
A professional CPT cultivates a referral network before it is needed — physicians, physical therapists, registered dietitians, mental-health professionals, and pelvic-floor specialists — so that when a situation exceeds scope, the trainer can hand off smoothly rather than improvise. NASM distinguishes clearly between providing general guidance (which trainers may do) and specific clinical services (which they may not). The table below maps common requests to the appropriate professional:
| Client need / request | In CPT scope? | Refer to |
|---|---|---|
| Diagnose pain or an injury | No | Physician / physical therapist |
| Specific calorie/macro meal plan | No | Registered dietitian |
| Treat or rehab a diagnosed injury | No | Physical therapist |
| Adjust medication or dosing | No | Prescribing physician |
| Counsel for an eating disorder or depression | No | Licensed mental-health professional |
| General nutrition and lifestyle tips | Yes | (trainer, within scope) |
| Design a safe, cleared exercise program | Yes | (trainer, within scope) |
A practical screen for whether something is a red flag requiring referral versus a trainable finding: ask whether the issue is a symptom of possible pathology (pain at rest, night pain, unexplained weakness, numbness, radiating pain, dizziness, chest discomfort, unexplained weight change) or a movement-quality finding (a correctable compensation, limited range, weak stabilizers). Pathology-type findings are referred; movement-quality findings are coached.
Documentation, Consent, and the Exam Mindset
Documentation is both a professional and a legal safeguard. The trainer records the clearance status, specific restrictions, the modifications applied, any symptoms reported, the referral made, and the client's response, using objective, observation-based language — never a diagnostic label the trainer invented. Before communicating with a client's healthcare provider, the trainer obtains written informed consent to share personal health information, respecting confidentiality.
On exam day, the reliable mindset is to look past the confident-sounding-but-unsafe option: the answer that diagnoses, medicates, ignores a red flag, or forces a standard protocol is almost always wrong. The defensible choice protects the client, preserves scope, documents the decision, and refers what the trainer is not qualified to interpret — while still progressing the client through every variable the trainer is qualified to control.
A client asks the trainer to determine whether their knee pain is a meniscus tear. What is the best response?
A client develops chest pain and sudden shortness of breath mid-session. What is the trainer's correct primary action?
How does a relative contraindication differ from an absolute contraindication?
A client's physician note simply says "cleared for exercise." The client has a back condition and wants heavy loaded spinal flexion. What should the trainer do?
