Setup
- Lie flat on your back on a mat with your legs extended or knees bent for lower back comfort.
- Position your arms straight at your sides with your palms facing your thighs.
- Ensure your head, upper back, and sacrum are in firm contact with the floor and your chin is slightly tucked.
How to do it
- Exhale as you shrug your shoulders toward your ears, sliding your shoulder blades upward along the floor.
- Squeeze your upper traps at the top of the movement for a one-second pause to maximize muscle fiber recruitment.
- Inhale as you slowly return your shoulders to the neutral starting position using a controlled tempo.
- Maintain a 2-1-2 tempo: two seconds to shrug up, one second hold, and two seconds to lower.
Form checklist
- Keep your arms straight and relaxed; do not use your arms to pull the weight.
- Maintain constant head contact with the floor to avoid straining the neck muscles.
- Focus on moving the shoulder blades vertically rather than rolling the shoulders forward.
- Keep your core slightly engaged to prevent the lower back from arching off the floor.
Pro tips
- Imagine trying to touch the tops of your shoulders to your earlobes to ensure a full range of motion.
- Focus on the 'slide' of the scapula against the floor to ensure the movement is driven purely by the traps rather than momentum.
Make it harder
- Increase the time under tension by implementing a 5-second isometric hold at the peak of the contraction.
- Perform the movement with your arms raised overhead in a 'Y' position to change the leverage and increase the demand on the trapezius.
