What is the plane of movement for leg press?

The plane of movement for the leg press primarily occurs in the sagittal plane, which divides the body into right and left halves. This exercise involves flexion and extension at the knee and hip joints as the legs push the weighted platform away and then return to the starting position. While the primary motion is in the sagittal plane, there can be some stabilization and engagement of muscles in the frontal and transverse planes as well.
