The ACE IFT Model for the CPT Exam: Six Phases, Three Intensity Zones and Five Movement Patterns

The ACE IFT Model splits training into a cardiorespiratory and a muscular component, each with three phases. Here is what each phase focuses on, how VT1, VT2 and the talk test define ACE's three intensity zones, how the five movement patterns fit in, and the mix-ups that cost points.

Short answer

The ACE Integrated Fitness Training (IFT) Model has two training components, cardiorespiratory and muscular, and each has three phases. Cardiorespiratory training moves from Base Training to Fitness Training to Performance Training, with intensity set by three zones separated by the first and second ventilatory thresholds (VT1 and VT2). Muscular training moves from Functional Training to Movement Training to Load/Speed Training, built on five movement patterns: bend-and-lift, single-leg, push, pull and rotation. A client can be in a different phase for each component.

The ACE IFT Model in one table

ACE's IFT Model page describes two training components, cardiorespiratory training and muscular training, "comprised of three training phases." Depending on health, fitness and goals, ACE says "every client will fall within one of the phases for each training component." The phase names and focus below come from ACE's free IFT Model Exercise Programming Template, checked on October 27, 2026, in Passy's own words.

PhaseCardiorespiratory trainingMuscular training
1Base Training: moderate-intensity exercise below the talk-test thresholdFunctional Training: postural stability and kinetic chain mobility
2Fitness Training: adds intervals in zone 2, from VT1 to just below VT2Movement Training: trains the five primary movement patterns, with Functional Training exercises in the warm-up and cool-down
3Performance Training: adds intervals in zone 3, at and above VT2Load/Speed Training: loads the movement patterns toward load and speed goals, still with Functional Training in the warm-up and cool-down

The two columns are independent. A client can be in Fitness Training for cardio and Functional Training for muscular work at the same time, and a scenario question can turn on that.

How the ACE IFT Model shows up on the ACE CPT exam

The ACE Personal Trainer Exam Content Outline doesn't use the name "IFT Model." It lists the job tasks the model organizes. Domain II asks you to monitor cardiorespiratory responses with "heart rate, ventilatory thresholds, rating of perceived exertion" and to design cardio programs "based on individualized exercise responses (e.g., heart rate, ventilatory thresholds)." Domains I and III name the foundational movement patterns (bend-and-lift, single-leg, push, pull, rotation) and their variations and modifications.

ACE's study program teaches those tasks through the IFT Model, so expect scenario questions that ask, in effect: which phase is this client in, which zone is this intensity, and what should change next? That's Passy's reading of the outline and the study program, not an ACE statement about item counts. Because the model spans several domains, it helps to see all four domains planned for full ACE CPT prep and where cardio and movement tasks sit among them.

ACE's three intensity zones, VT1 and VT2

ACE's January 2025 Certified article, Talkin' About the Talk Test: Intensity Matters, sets out the three-zone intensity model used with the IFT Model's cardio phases:

ZoneHeart-rate rangeTalk test
Zone 1Below VT1Can talk comfortably
Zone 2From VT1 to just below VT2Not sure talking is comfortable
Zone 3At and above VT2Definitely can't talk comfortably

The two thresholds are the boundaries:

  • VT1 (first ventilatory threshold). The article explains that at about VT1, breathing rate rises and comfortable speech is no longer possible. That's why the talk test can find it. ACE Answers notes that other texts call VT1 the lactate threshold or the anaerobic threshold.
  • VT2 (second ventilatory threshold). A second, sharper rise in breathing. The article says VT2 matches the onset of blood lactate accumulation and is the highest intensity a well-trained person can sustain for 30 to 60 minutes. ACE Answers adds the alternative name respiratory compensation threshold.

ACE uses VT1 and VT2 rather than "anaerobic threshold" because, as ACE Answers puts it, that term "has come to mean different things in various parts of the world." On the exam, use ACE's terms.

How each ACE cardio phase uses the zones

  • Base Training stays below the talk-test threshold, with the focus on enjoyment and on more frequent, longer sessions. The article says clients stay in this phase until they can do at least 20 minutes of cardio below the talk-test threshold at least three times a week.
  • Fitness Training introduces vigorous intervals, with work in zone 2 and recovery in zone 1.
  • Performance Training uses periodized programs that spend time in all three zones.

Three ACE field tests for the thresholds

TestWhat it estimatesWhat it needs
Talk testWhether intensity is below, near or above VT1 (and, roughly, whether it has reached VT2)Nothing. Ask the client to recite something familiar, then ask whether they can speak comfortably
Submaximal talk test for VT1The heart rate at VT1Continuous heart-rate monitoring and small stepwise increases in intensity
VT2 threshold assessmentAn estimate of VT2A 20-minute bout at the highest steady intensity the client can hold. It requires high conditioning and pacing experience

ACE Answers draws the line clearly: the talk test monitors intensity without measuring heart rate, while the submaximal talk test is a formal assessment that measures heart rate at VT1.

Questions that combine a client's talk-test answer with a program decision are a natural fit for scenario practice. Planned ACE CPT questions on IFT phases and ventilatory-threshold zones work through that kind of decision, with each option explained.

ACE IFT muscular training: Functional, Movement and Load/Speed

The muscular side builds from control to patterns to load:

  1. Functional Training is phase 1. The template's focus is postural stability and kinetic chain mobility: in plain terms, controlling posture and having the mobility each joint in the chain needs, before adding complexity.
  2. Movement Training trains the five primary movement patterns. The outline lists them as bend-and-lift, single-leg, push, pull and rotation. Functional Training exercises stay in the warm-up and cool-down.
  3. Load/Speed Training loads those patterns for clients whose goals call for more load or speed, while Functional Training work stays in the warm-up and cool-down.

ACE's free resources include assessment protocols for each pattern (bend-and-lift, single-leg, push, pull and rotation) among its ACE Answers forms. The handbook says video items show "a common exercise movement," so these patterns are a sensible place to practice. If you can describe good form in each pattern and spot its typical deviations, you're preparing for both kinds of question at once. The ACE CPT exam format guide explains how the silent video items work.

A worked ACE IFT cardio example (fictional client)

This is Passy's own illustration, not an ACE exam item. It applies only the Base Training benchmark and the talk-test reading from ACE's article.

Rosa, 41, cardio. She walks briskly for 25 minutes four times a week and can chat throughout. She wants to improve her fitness. She already meets ACE's Base Training benchmark (at least 20 minutes below the talk-test threshold, at least three times a week), so the next step is Fitness Training: zone 2 intervals with recovery in zone 1.

Rosa, during an interval. Asked to recite a familiar phrase, she says she can talk "but I'm not sure it's comfortable." By ACE's talk-test reading, she's around VT1, the start of zone 2. If the goal was a zone 2 interval, the intensity is about right.

ACE IFT mix-ups that cost points

  • Base vs Functional. Both are phase 1, but Base Training is cardio and Functional Training is muscular. Read which component the question is about.
  • ACE's zone 2 starts at VT1. In ACE's model, zone 2 runs from VT1 to just below VT2. If you've seen "zone 2" used elsewhere for easy, conversational training, don't carry that meaning into an ACE question. Easy, conversational work is zone 1 in ACE's model.
  • VT1 vs VT2 names. Lactate threshold and anaerobic threshold map to VT1. Respiratory compensation threshold and onset of blood lactate accumulation map to VT2.
  • One phase for everything. Each component has its own phase. A question may give you a client who is advanced in one and a beginner in the other.
  • Talk test vs submaximal talk test. The first needs no heart-rate data. The second exists to find the heart rate at VT1.

Where behavior change fits into the ACE IFT Model

ACE's IFT page says the model emphasizes "active listening, collaborative goal setting, and rapport development." Its behavior-change side is the ACE Mover Method, which ACE's Mover Method page puts into practice through the ABC Approach:

  • Ask open-ended questions to learn what the client hopes to achieve
  • Break down barriers with probing questions about what could get in the way
  • Collaborate to set SMART goals and specific action steps

On the exam, that means a programming question can turn on a coaching detail: the right next step may be a question to the client, not a new exercise. The outline also names OARS, the GROW model and the transtheoretical model, and GROW, OARS and the other coaching terms are planned as ACE CPT flashcards alongside the movement patterns.
