Suitcase Carry: Understanding, Benefits, and Proper Execution for Core Strength

What is a Suitcase Carry for Core?

The suitcase carry is a highly effective, unilateral loaded exercise designed to challenge and strengthen the core's ability to resist lateral flexion, mimicking the real-world demands of carrying an uneven load.

Understanding the Suitcase Carry

The suitcase carry is a foundational core exercise belonging to the family of "loaded carries," which includes variations like the farmer's walk, overhead carry, and rack carry. What distinguishes the suitcase carry is its unilateral loading: you hold a single heavy weight (like a dumbbell, kettlebell, or even a literal suitcase) in one hand, allowing the other arm to hang freely. This asymmetrical load immediately creates a significant challenge for your core musculature. Unlike traditional abdominal exercises that focus on flexion (e.g., crunches) or rotation (e.g., Russian twists), the suitcase carry primarily targets the core's anti-lateral flexion capabilities, forcing the muscles of the trunk to work intensely to prevent the body from bending sideways towards the loaded side.

Anatomy and Biomechanics: How it Engages the Core

The efficacy of the suitcase carry lies in its direct engagement of the core's deep stabilizing muscles. When you hold a heavy weight in one hand, gravity attempts to pull your torso towards that side. Your body's core, particularly the muscles on the opposite side of the load, must powerfully contract to maintain an upright, neutral spine.

• Key Muscles Involved:

  • Quadratus Lumborum (QL): This deep abdominal muscle, running from your pelvis to your lowest rib, is a primary anti-lateral flexor. On the side opposite the load, the QL contracts isometrically to prevent your spine from bending.
  • Internal and External Obliques: These muscles, particularly those on the side opposite the load, work in conjunction with the QL to stabilize the trunk and resist lateral bending and rotation.
  • Transverse Abdominis (TVA): As the deepest abdominal muscle, the TVA acts like a natural corset, providing circumferential stability to the entire lumbar spine and pelvis. It plays a crucial role in bracing the core throughout the movement.
  • Erector Spinae: These muscles along the spine work to maintain an upright posture and resist flexion or extension, contributing to overall spinal stability.
  • Gluteus Medius: While primarily a hip abductor, the gluteus medius on the stance leg helps stabilize the pelvis, which is critical for maintaining an upright torso during gait.

• Mechanism of Action (Anti-Movement): The suitcase carry is an "anti-movement" exercise. Instead of creating movement (like a sit-up), the core's primary role is to resist unwanted movement. In this case, it's resisting lateral flexion and, to a lesser extent, rotation. This type of training is highly functional, as our daily lives and athletic endeavors constantly demand our core to stabilize against external forces rather than just produce movement.

Benefits of Incorporating the Suitcase Carry

Integrating the suitcase carry into your training regimen offers a multitude of benefits that extend far beyond aesthetics.

• Enhanced Core Stability and Strength: It builds robust, functional core strength that translates to better performance in nearly all physical activities and sports. It teaches the core to brace effectively under load.
• Improved Posture: By strengthening the muscles responsible for maintaining an upright posture and resisting imbalances, the suitcase carry can help correct postural deviations and alleviate associated pain.
• Increased Grip Strength: While a core exercise, the isometric contraction required to hold the heavy weight significantly taxes the forearm and hand muscles, leading to substantial improvements in grip strength.
• Functional Strength and Real-World Application: This exercise directly mimics real-life scenarios like carrying groceries, luggage, or even a child, making you stronger and more resilient in daily tasks.
• Reduced Risk of Lower Back Pain: A strong, stable core is paramount for protecting the lumbar spine. By training the anti-lateral flexion capabilities, the suitcase carry helps prevent injuries often caused by instability or sudden, unbalanced loads.
• Improved Balance and Proprioception: The unilateral load challenges your balance and forces your body to constantly make small adjustments, enhancing your proprioception (your body's awareness in space).

Proper Execution of the Suitcase Carry

Executing the suitcase carry correctly is crucial to maximize its benefits and minimize injury risk.

• Starting Position:

  • Stand tall with your feet hip-width apart, spine neutral.
  • Place a dumbbell, kettlebell, or other heavy object on the floor beside one foot.
  • Squat down with a straight back to grasp the handle firmly.
  • Stand up, holding the weight in one hand, allowing the other arm to hang naturally by your side.
  • Ensure your shoulders are pulled back and down, and your chest is proud. Avoid shrugging the loaded shoulder.

• Movement:

  • Maintain a tall, upright posture throughout the entire movement. Resist the urge to lean away from the weight.
  • Brace your core as if preparing to be punched in the stomach. This engages the TVA and obliques.
  • Walk slowly and deliberately, taking controlled steps. Focus on maintaining balance and spinal neutrality.
  • Keep your gaze forward.

• Key Cues:

  • "Stay Tall": Imagine a string pulling you up from the crown of your head.
  • "Brace Your Core": Think of creating a rigid cylinder around your torso.
  • "Shoulders Down and Back": Prevent the weight from pulling your shoulder up towards your ear.
  • "No Leaning": Actively resist the lateral pull of the weight. Your goal is to keep your torso perfectly perpendicular to the floor.

• Common Mistakes to Avoid:

  • Leaning Away from the Weight: This indicates the weight is too heavy or you're not engaging your core properly.
  • Shrugging the Loaded Shoulder: This puts undue strain on the trapezius and neck muscles.
  • Rounding the Back: Compromises spinal integrity.
  • Rushing the Movement: Slow, controlled steps are key for maximizing core engagement.
  • Letting the Weight Swing: Keep the weight close to your body.

Programming Considerations

• Weight Selection: Start with a moderate weight that challenges your core without compromising form. You should be able to maintain a perfectly upright posture. Progress gradually as your strength improves.
• Distance/Time: A good starting point is walking for 20-40 meters (60-120 feet) per side, or for 30-60 seconds per side. Perform 2-4 sets.
• Integration: The suitcase carry can be incorporated in various parts of your workout:
  • Warm-up: As a core activation drill.
  • Accessory Work: After your main strength lifts.
  • Finisher: To tax the core and grip at the end of a session.
• Progression: Increase the weight, increase the distance/time, or try performing it with bare feet to enhance proprioception.
• Regression: Decrease the weight, reduce the distance, or perform it for shorter durations.

Who Can Benefit?

Virtually anyone looking to improve functional strength and core stability can benefit from the suitcase carry. This includes:

• Athletes: Enhances performance in sports requiring unilateral loading or rotational stability (e.g., baseball, golf, tennis, combat sports).
• General Population: Improves daily functional tasks and reduces the risk of lower back pain.
• Individuals with Desk Jobs: Helps counteract the effects of prolonged sitting by strengthening postural muscles.
• Those Recovering from Injuries: Under professional guidance, it can be a valuable tool for rebuilding core stability after certain injuries.

Conclusion

The suitcase carry is an indispensable exercise for building a truly functional and resilient core. By specifically targeting the core's ability to resist lateral flexion, it strengthens the deep stabilizing muscles that are often neglected by more traditional abdominal exercises. Its direct translation to real-world strength and its profound benefits for posture, injury prevention, and overall athleticism make it a cornerstone movement for anyone serious about comprehensive fitness and long-term health.
