Weighted Sandbag Carry Shoulders

  • Intermediate
  • Compound
  • Timed hold
  • Back
  • Lower legs
  • Shoulders
  • Upper legs
  • Waist

This functional carry builds exceptional core stability and lower-body endurance by forcing the body to stabilize a shifting, uneven load across the upper back. It targets the traps and core for stability while the legs drive the movement through a constant state of tension.

Setup

  1. Stand with feet shoulder-width apart and the sandbag on the floor in front of you.
  2. Clean the sandbag up to your chest, then carefully transition it over your head to rest across your upper traps.
  3. Grip the handles or the ends of the bag firmly to secure it tightly against your shoulders.
  4. Stand tall with your ribs tucked, glutes squeezed, and your core fully braced.

How to do it

  1. Begin walking forward using short, controlled steps to maintain balance against the shifting weight of the sand.
  2. Maintain a rhythmic breathing pattern, taking shallow breaths into a braced core to maintain internal pressure.
  3. Walk for the prescribed distance or time, keeping your torso perfectly vertical and avoiding any forward or backward lean.
  4. To finish, stop completely before carefully hinging at the hips to lower the bag to the floor.

Form checklist

  • Keep your chest up and shoulders pulled back to prevent the bag from rounding your spine.
  • Maintain a neutral neck position; do not let the weight push your head forward.
  • Ensure your hips stay level with every step, avoiding any side-to-side swaying.
  • Keep your core 'braced for a punch' throughout the entire duration of the carry.

Pro tips

  • Focus on 'crushing' the handles or the bag with your hands to create irradiation, which increases shoulder and core stability.
  • If the sand shifts to one side, resist the urge to tilt; use your obliques to counteract the lateral pull and stay centered.

Make it harder

  • Perform the carry on an incline or uneven terrain to significantly increase the demand on your calves and stabilizers.
  • Incorporate 'stop-and-go' intervals where you pause every five steps to hold a static, braced position for 3 seconds.
