Question #: 43
Topic #: 5
A trainer is preparing to have a client perform an active kneeling hip flexor stretch. Which of the following instructions should the trainer give the client?
A.
"Perform 2 sets of 12 to 15 repetitions."
B.
"Perform as quickly as can be controlled for 10 repetitions."
C.
"Hold the stretch for 30 seconds and perform 1 to 3 repetitions."
D.
"Hold the stretch for 2 seconds and perform 5 to 10 repetitions."
The active kneeling hip flexor stretch falls under active stretching in NASM’s flexibility continuum. Active stretching uses the agonist muscle to move the limb through a range of motion while the antagonist is stretched, typically holding the end range for about 1–2 seconds before returning to the start position. The NASM CPT7 Study Guide specifies that active stretches are performed for 5–10 repetitions, holding each for 1–2 seconds.
This technique is most often applied in the strength level of the OPT model, often following the warm-up and before resistance training to prepare muscles for dynamic activity. Options A and C represent repetition and hold counts more typical of resistance or static stretching, while Option B’s “as quickly as can be controlled” describes dynamic stretching or plyometric work—not an active isolated stretch. Therefore, the correct coaching instruction is to hold for 2 seconds and perform 5–10 repetitions.
