Quadruped Shoulder Cars

Quadruped Shoulder Cars Exercise Description

Quadruped Shoulder CARs are an active mobility drill that moves the shoulder through its full, pain‑free range while you stabilize your trunk. From an all‑fours position, you create a large, controlled arm circle that includes flexion, abduction, extension, and internal/external rotation at the glenohumeral joint. The supporting side maintains scapular stability against the floor, encouraging neutral spine and minimizing torso compensation. Primary musculature includes the rotator cuff and deltoids of the moving arm, with the serratus anterior, trapezius, and rhomboids assisting scapular control; the core resists rotation. Use slow, deliberate motion to explore end ranges with control and consistent tension rather than speed.

How To Do The Quadruped Shoulder Cars Exercise

‘- Set up on all fours: hands under shoulders, knees under hips, spine neutral, gaze down.
– Spread fingers and grip the floor; lightly brace your abdomen and keep ribs stacked over pelvis.
– “Pack” the supporting shoulder by gently drawing the scapula down and back without shrugging.
– Extend the free arm straight beside your body with the thumb pointing forward; create light tension in a soft fist.
– Begin the circle: reach the arm forward and up into flexion, rotating externally so the palm turns outward; keep elbow straight.
– Continue across the top, then rotate internally as the arm sweeps behind into extension; keep chest square and hips level.
– Finish the arc back to the start, maintaining smooth, controlled motion and steady breathing.
– Reverse the path for the opposite direction, matching speed and range.
– Stay within pain‑free end ranges; pause briefly at the edges without forcing motion.
– Common faults to avoid: bending the elbow, arching the low back, shrugging, or twisting the torso to “cheat” range.

Quadruped Shoulder Cars Tips

‘- Keep hands directly under shoulders and knees under hips to maintain a neutral spine.
– Spread your fingers and actively grip the floor to help stabilize your supporting side.
– Lightly brace your abdomen so the ribs stay stacked over the pelvis as the arm moves.
– Gently draw the supporting shoulder blade down and back without shrugging to “pack” the shoulder.
– Keep the moving arm straight with a soft fist and thumb pointing forward at the start.
– As you lift into flexion, rotate the arm so the palm turns outward while keeping the elbow locked.
– Keep your chest square and hips level so the trunk doesn’t twist to gain extra range.
– Move in a slow, controlled circle, matching speed and range in both directions.
– Stay within a pain‑free range and pause briefly at the end positions instead of forcing motion.
– Watch for and avoid bending the elbow, arching the low back, shrugging, or twisting the torso.

Quadruped Shoulder Cars Beginner Introduction

Quadruped Shoulder CARs are a shoulder‑mobility drill performed in a hands‑and‑knees position, emphasizing smooth motion at the shoulder while the rest of the body stays steady. One arm supports the torso against the floor, while the other arm moves through a slow, spacious circular path, exploring how far the shoulder can comfortably move in different directions. The action involves lifting the arm, sweeping it out to the side, reaching it behind the body, and rotating it through these positions with steady, controlled effort rather than quick reps.

This pattern highlights the small stabilizing muscles around the shoulder along with the larger shoulder muscles of the moving arm. At the same time, the supporting side, upper back, and chest muscles contribute to steady shoulder blade control against the ground. The core works to limit excess twisting or arching, so the circle comes from the shoulder joint rather than the spine or hips. Overall, the drill centers on slow control, consistent tension, and mindful awareness of comfortable limits in shoulder movement.
