Which plane divides the body into the right and left sides?

The sagittal plane is the plane that divides the body into right and left sides. It runs vertically from front to back and allows for movements that involve flexion and extension, such as bending forward or backward, or raising and lowering arms and legs. This division is significant in understanding body movements and positioning in various exercises, as many activities occur in this plane. For example, actions like squats and lunges primarily happen in the sagittal plane, as they involve movement forward and backward, targeting muscles appropriately on either side of the body.

The other planes mentioned define different divisions of the body. The frontal plane divides the body into anterior (front) and posterior (back) sections, allowing for movements such as side lunges and jumping jacks. The transverse plane splits the body into upper (superior) and lower (inferior) parts, focusing on rotational movements like twists. Lastly, the term "coronal plane" typically refers to the same concept as the frontal plane. Thus, understanding these planes is crucial for a comprehensive grasp of body movements and their applications in fitness training.
