Transverse plane cuts the body into top and bottom halves. Twisting movements.
The transverse abdominis muscle is the deepest muscle in the abdomen. It won’t give you the much desired six pack look but this unsung hero of the abdominal muscles, acts as a natural lifting belt keeping our internal organs protected and giving support to the pelvic and lumbar region. So why not try working your transverse abdominis using a transverse plane of movement, such as a cycles (lying on your back with your hands behind your head and feet off the floor, extend one leg while curling up touching your elbow to your bent knee, repeat other side).
