Section 1: The 4x4 Matrix & Functional Exercise Progressions
(Q1–35)
Q1. According to the 4x4 Matrix, what type of resistance is used in a barbell front
squat?
A) 1
B) 2
C) 3
D) 4
Answer: D
Rationale: The barbell front squat is an advanced, full-body exercise using external
load and high stability demands — the "Capacity" phase in the matrix.
Q2. What are the Three R's in the TPI corrective exercise sequence?
A) Reset, Re-Enforce, Reload
B) Restore, Rebuild, Rehabilitate
C) Regress, Regenerate, Rest
D) Reset, Release, Rebuild
Answer: A
Rationale: These represent the corrective sequence — restore movement (Reset),
strengthen pattern (Re-Enforce), and challenge under load (Reload).
Q3. What does JMD stand for in TPI terminology?
A) Joint Mobility Dysfunction
,B) Joint Muscular Deficiency
C) Joint Movement Disorder
D) Joint Mobility Deficiency
Answer: A
Rationale: JMD = Joint Mobility Dysfunction, which limits joint motion. TED =
Tissue Extensibility Dysfunction, which limits soft tissue flexibility.
Q4. What does TED stand for in TPI terminology?
A) Tissue Extensibility Dysfunction
B) Tendon Elasticity Disorder
C) Tissue Elasticity Deficiency
D) Tendon Extensibility Dysfunction
Answer: A
Rationale: TED = Tissue Extensibility Dysfunction, which limits soft tissue
flexibility.
Q5. In the 3x3 strength matrix, which is the first progression?
A) Split Stance
B) Single Leg Stance
C) Bilateral Stance
D) Tandem Stance
Answer: A
Rationale: Split Stance is the first progression in the 3x3 strength matrix. It bridges
bilateral to single-leg work by adding instability but maintaining support.
Q6. What are the four Functional Exercise Positions in the 4x4 Matrix?
A) Supported, Suspended, Stacked, Standing
B) Seated, Kneeling, Standing, Lying
C) Supine, Prone, Side-Lying, Standing
D) Supported, Seated, Standing, Moving
Answer: A
,Rationale: The four functional exercise positions are Supported, Suspended,
Stacked, and Standing. These represent progressive body positions from most to
least stable.
Q7. What are the four Functional Exercise Resistance Types in the 4x4 Matrix?
A) Feedback, Demonstrate, Capacity with Feedback, Capacity
B) Light, Moderate, Heavy, Maximal
C) Isometric, Concentric, Eccentric, Dynamic
D) Bodyweight, Band, Dumbbell, Barbell
Answer: A
Rationale: The four resistance progressions are Feedback, Demonstrate, Capacity
with Feedback, and Capacity. These move from light/assisted to full load under
dynamic conditions.
Q8. Which position in the 4x4 Matrix introduces the client to a weight-bearing hip
and spine first?
A) 1
B) 2
C) 3
D) 4
Answer: C
Rationale: Position 3 in the 4x4 Matrix introduces the client to a weight-bearing
hip and spine first.
Q9. When training, what is the correct progression through the 4x4 Matrix?
A) 1-1 to 1-2 to 2-1 to 2-2 to 3-1 to 3-2 to 4-1 to 4-2, then all 3 and 4 variations
B) 1-1 to 2-1 to 3-1 to 4-1, then complexity
C) 4-4 to 3-3 to 2-2 to 1-1
D) Random order based on client preference
Answer: A
Rationale: The recommended progression is 1-1 to 1-2 to 2-1 to 2-2 to 3-1 to 3-2 to
4-1 to 4-2, then follow up with all the 3 and 4 variations of complexity (resistance).
, Q10. Which exercise is the easiest to perform according to the 3x3 strength
matrix?
A) Split Stance Squat Two Hands One Dumbbell
B) Single Leg Squat One Hand One Dumbbell Contralateral
C) Bilateral Squat with Barbell
D) Single Leg Squat Bodyweight
Answer: A
Rationale: Split Stance Squat Two Hands One Dumbbell is considered the easiest
to perform in the 3x3 strength matrix progression.
Q11. Which exercise is considered harder: Single Leg Squat One Hand One
Dumbbell Contralateral or Split Stance Squat Two Hands One Dumbbell?
A) Single Leg Squat One Hand One Dumbbell Contralateral
B) Split Stance Squat Two Hands One Dumbbell
C) They are equally difficult
D) Neither is difficult
Answer: A
Rationale: Single Leg Squat One Hand One Dumbbell Contralateral is considered
harder due to the single-leg stance, contralateral load, and increased stability
demands.
Q12. What is the most challenging stance for strength training?
A) Single leg stance
B) Split stance
C) Bilateral stance
D) Tandem stance
Answer: A
Rationale: Single leg stance is the most challenging stance for strength training due
to the high stability demands and reduced base of support.
Q13. Any time you pre-activate the core stabilizers before the actual exercise
begins, what type of resistance does this represent?
A) 1
