START BY BODY REGION
Spine & rib cage
Begin with breathing mechanics and comfortable trunk movement before adding speed, range, or load.

Asymmetric Weight Shift
People rarely load both sides exactly equally. A weight shift becomes useful to explore when it is new, painful, difficult to control, or clearly limits a task.
Excessive Anterior Pelvic Tilt
An anterior pelvic tilt is an observation that can vary with stance, anatomy, breathing, and the task. Focus on comfort, function, and change after movement rather than appearance alone.
Excessive Forward Trunk Lean
Forward trunk lean can be an efficient strategy depending on body proportions, load, and task. Explore it when the position is uncomfortable, difficult to control, or limits the activity you want to perform.
Excessive Posterior Pelvic Tilt
A posterior pelvic tilt can appear during sitting, standing, or loaded movement and may be a normal task strategy. Explore alternatives when it is paired with discomfort, stiffness, or reduced movement options.
Forward Head Posture
A forward head position is a common observation, not a diagnosis by itself. Use workstation changes and low-load movement to see whether comfort, control, or task tolerance improves.
Rib Flare
The lower ribs may appear prominent because of anatomy, breathing strategy, trunk position, or the task. Appearance alone is not a diagnosis; focus on comfort, breathing ease, and movement choices.
Rounded Shoulders
Shoulders resting forward can reflect habit, task demands, anatomy, or fatigue. Resting appearance alone does not diagnose a problem; movement comfort and function matter more.
Scapular Anterior Tilt
The shoulder blade changes orientation as the arm moves, and resting position varies between people. Explore anterior tilt only when it accompanies pain, poor control, or limited reaching—not from appearance alone.
Shoulder Elevation
Shoulders naturally elevate during many reaching and loading tasks. Explore the pattern when it is paired with neck effort, pain, asymmetry, or reduced task tolerance rather than trying to keep the shoulders down at all times.
