Sagittal Plane
Forward-and-back movement. Many familiar strength exercises live mostly here.

Planes of Motion: Training in Different Directions
A simple interactive model showing how exercises move through the sagittal, frontal, and transverse planes.
Plain-English concept
The body moves in more than one direction.
A plane of motion is a simple way to describe the direction of movement. Some exercises move mostly forward and backward, some move side to side, and some rotate.
This model is intentionally simplified. It helps explain the idea clearly, but real exercises can combine directions and can change based on setup, intent, and anatomy.
Interactive model
Play a movement and watch the plane it lives in.
Pick an exercise and watch the dotted trail it draws. The highlighted sheet is the plane that movement mostly stays in. Switch to front, side, or top view to see it straight on.

What this means in training
Why planes of motion matter
You do not need to memorize the names. The point is understanding what direction your body is being challenged.
Side-to-side control
Frontal Plane
Movement away from the midline or back toward it. This matters for hips, shoulders, and lateral control.

Rotation and anti-rotation
Transverse Plane
Rotational movement around the body. This can include turning, resisting rotation, or throwing.
