Xercizer Reformer Program Practice Test

Which exercise is named Single Knee Extension?

Pelvic Stabilization #6 Pelvic Stabilization #8 Pelvic Stabilization #9 Pelvic Stabilization #7

Correct Answer:

Pelvic Stabilization #8

Explanation:

The move tested is about naming and recognizing a specific leg movement within the Pelvic Stabilization set. Single Knee Extension describes extending one knee while keeping the pelvis stable and level. That focus—one leg extending, with the pelvis remaining steady—is why the variation that carries this name fits best. It trains knee extension control without allowing the pelvis to tilt or rotate, which also helps protect the lower back and cue proper alignment. Other Pelvic Stabilization variations involve different tasks or alignments that don’t center on extending a single knee, so they aren’t labeled Single Knee Extension.
