The most common plane of movement, the sagittal plane, divides the body into right and left halves. In this plane, we use the strength of our muscles to move forward or backward (flexion and extension). Key muscles such as the quadriceps, gluteals and biceps are typically worked in the sagittal plane: for example, a lunge forward or backward, which can be made more challenging by adding another sagittal exercise such as a bicep curl.
The transverse plane, the plane most overlooked in exercise routines, divides the body into top and bottom halves. Movements in this plane are rotational in nature and critical in sports for pivoting, batting and golf swings. Common transverse plane muscle groups include the gluteal and adductor muscle groups and the rotator cuff. An example of an exercise in this plane would include a chop with a medicine ball.
