Air Squats and kettlebell swings are examples of movements in which plane?

• A. Frontal Plane
• B. Sagittal Plane
• C. Transverse Plane
• D. Diagonal Plane

Answer: (B)

The main idea here is identifying the plane of motion that these movements predominantly use. Air squats and kettlebell swings are focused on forward and backward movement, which corresponds to the sagittal plane. In this plane, joints mainly perform flexion and extension as you bend at the hips and knees on the descent and extend to rise, or hinge at the hips and drive the movement forward and upward in a mostly front-to-back path.

Frontal plane movements would involve side-to-side actions like abduction and adduction, which isn’t the dominant pattern in squats or swings. Transverse plane involves rotation, which is minimal in these two movements. The diagonal plane isn’t the standard classification for these primary motions. So the sagittal plane best describes these movements because of the emphasis on flexion/extension in a front-to-back path.
