ACSM CPT key terms

A short self-report screening questionnaire that flags diagnosed conditions or symptoms needing medical clearance before a person starts or increases physical activity; positive answers lead to follow-up questions.

A structured form that collects past and present medical conditions, surgeries, medications, allergies, family history, and lifestyle habits so the trainer can spot contraindications and plan safe exercise.

Sorting clients into low, moderate, or high risk using symptoms, known disease, and the number of risk factors, which determines whether medical clearance or supervised testing is needed.

Warning indicators such as chest pain, unusual shortness of breath, dizziness, fainting, ankle swelling, and palpitations that call for stopping exercise and referring the client for medical evaluation.

A screening ratio of body weight in kilograms divided by height in meters squared that classifies underweight, normal, overweight, and obesity but does not separate fat from lean tissue.

A tape measurement taken around the abdomen, usually at the top of the hip bone, used alongside BMI to estimate abdominal fat and cardiometabolic risk.

A caliper technique that pinches subcutaneous fat at standard sites and inserts the summed values into an equation to estimate body fat percentage; technique and tester reliability matter.

A graded effort below all-out intensity, such as a cycle or step protocol, from which maximal oxygen uptake is estimated by extrapolating the heart rate response to a predicted maximum.

The highest rate at which the body can take up and use oxygen during exercise, expressed in milliliters per kilogram per minute and strongly linked to health outcomes.

A field test of hamstring and low-back flexibility performed seated with legs extended, measuring how far the client reaches toward or past the toes.

A prescription framework that specifies frequency, intensity, time, type, volume, and progression for each fitness component, giving structure to an exercise program.

Systematically increasing training demand, through load, repetitions, sets, or duration, as the body adapts, so improvement continues without excessive fatigue or injury.

Planned variation of training variables across long, medium, and short cycles to manage fatigue, prevent plateaus, and peak the client for specific goals.

A brief preparatory phase of light aerobic activity and dynamic movements that raises body temperature, increases blood flow, and prepares joints and muscles for the conditioning bout.

A gradual reduction in intensity after conditioning, usually light activity plus stretching, that aids venous return and brings heart rate and blood pressure toward resting values.

Controlled, repeated movements that take a joint through its available range, used before activity to raise temperature and prepare the neuromuscular system rather than to lengthen tissue.

Holding a muscle in an elongated position for a set period, typically after activity or in a separate session, to improve range of motion.

The heaviest resistance a client can lift once with correct technique; it sets training loads expressed as percentages and tracks changes in maximal strength.

The capacity to repeat muscle actions or hold a contraction for an extended time, often assessed with push-up or curl-up tests and trained with higher repetitions.

The gap between maximal and resting heart rate; multiplying it by a chosen intensity percentage and adding resting heart rate produces a target training heart rate.

A subjective scale, often Borg 6 to 20 or 0 to 10, on which clients rate how hard exercise feels, useful when heart rate is unreliable or unavailable.

A unit that expresses exercise intensity as multiples of resting oxygen use, where one MET equals about 3.5 milliliters of oxygen per kilogram per minute.

Forcing exhalation against a closed airway while bracing, which sharply raises blood pressure; trainers teach clients to breathe out during effort instead when this is risky.

Objectives written to be specific, measurable, attainable, relevant, and time-bound, which makes progress easy to track and supports adherence to the program.

A behavior-change framework describing precontemplation, contemplation, preparation, action, and maintenance, used to match coaching and education to a client's current readiness.

A person's belief in their own ability to perform a specific task or behavior successfully; higher self-efficacy predicts better exercise adherence and persistence.

A collaborative counseling style using open-ended questions, reflective listening, and affirmation to help clients voice their own reasons for changing behavior.

The degree to which a client follows the agreed exercise plan over time; supported by realistic goals, social support, self-monitoring, and programming the client enjoys.

A comprehension check in which the client explains or demonstrates the instruction in their own words, revealing gaps the trainer can then correct.

Giving full attention to a client's words and feelings and reflecting them back, which builds trust and uncovers barriers, concerns, and preferences.

The legal and ethical boundaries of what a certified personal trainer may do: assess and program exercise, but not diagnose, treat, or prescribe diets or therapy.

Failure to give the care a reasonable professional would provide in similar circumstances, proven by duty, breach of that duty, causation, and resulting damages.

The level and type of care a competent professional with comparable training would provide in like circumstances; it is the benchmark used in liability claims.

A voluntary agreement given after the client understands the purpose, procedures, risks, benefits, and alternatives of assessment or exercise, documented in writing before participation.

A written, rehearsed procedure that assigns roles and specifies equipment locations, emergency contacts, and response steps for injury, cardiac arrest, or other crises.

A portable device that analyzes heart rhythm and delivers a shock for certain cardiac arrests; trainers should know where it is kept and how to apply it.

United States law governing how protected health information may be used and disclosed; fitness professionals keep client records private, secure, and shared only as permitted.

A policy that covers claims of injury or negligence arising from services provided; it supports but never replaces careful practice and thorough documentation.

The ongoing process of identifying hazards, reducing exposure through policies, paperwork, facility checks, and staff training, and preparing responses to emergencies.

A defined group of potential clients with shared needs and characteristics that a fitness business chooses to serve and aims its marketing messages toward.
