2 Moves to Bigger Traps (Trap Workout Musts!)
Summary
Jeff Cavaliere of Athlean-X explains why most people fail to fully develop their traps by training them in the wrong movement plane. By understanding the actual anatomy and fiber orientation of the trapezius, two targeted exercises can more effectively stimulate the upper, mid, and lower portions of the muscle.
Key Points
- The trapezius is a large muscle that originates at the back of the skull, runs down the spine, and attaches at the outer third of the clavicle and acromion — it does not run purely vertical.
- Standard vertical shrugs do not align with the true angle of the trap fibers, leaving significant muscle activation on the table.
- Angling your body relative to a cable or resistance source better separates the origin and insertion points, maximizing stretch and tension on the muscle.
- The traps perform multiple actions: elevation (shrugging), scapular retraction, and rotation — all three should be incorporated for full development.
- The lower and mid traps are just as important as the upper traps; they stabilize the scapula against the rib cage and help prevent shoulder impingement and injury.
- When performing plate raises, the traps only become the primary mover from roughly the mid-point upward — the front deltoid dominates the lower portion of the lift.
- The trapezius is built for muscular endurance, so training it with high rep ranges exposes it to the sustained tension it responds best to.
- Keeping the shoulder blades down and back during trap exercises reinforces proper scapular mechanics and maximizes trap engagement.
Exercise Details
1. Angled Cable Shrug with Rotation
- Target Muscles: Upper trapezius (primary), mid trapezius
- Setup: Position yourself at an angle to a low cable pulley so that the origin (skull/neck) and insertion (outer clavicle) are as far apart as possible at the start position.
- Form Cues:
- Begin with a shrug (elevation)
- Follow with a scapular retraction (squeeze shoulder blades together)
- Finish with a quarter-turn rotation of the torso
- The combined motion should feel fluid: shrug → rotate → pull
- Common Mistakes to Avoid:
- Performing only a straight vertical shrug, which ignores the diagonal fiber orientation of the muscle
- Neglecting the rotational component, which limits full trap recruitment
2. Incline Plate Raise (Modified)
- Target Muscles: Mid and lower trapezius, with upper trap involvement at the top of the range
- Setup: Rest a 25 lb plate on an inclined bench to serve as the starting (low) position, eliminating the lower range where the front delt dominates.
- Form Cues:
- Begin the raise from the incline bench level — not from hip height
- Raise the plate overhead in a controlled arc
- Lower eccentrically with control, then repeat
- Keep shoulder blades down and back throughout the movement
- Common Mistakes to Avoid:
- Starting the raise from a fully lowered position (hip/thigh level) — this shifts emphasis to the anterior deltoid rather than the traps
- Training exclusively for strength with low reps, missing the endurance-oriented nature of the trapezius
- Sets/Reps: Train to failure with high rep ranges to match the endurance capacity of the trap muscle fibers.
