Suitcase Carry: A Complete Guide

Quick Intro

Suitcase Carry, also called the Single Arm Carry, is a loaded carrying exercise performed by holding a heavy dumbbell or kettlebell in one hand only, the way a suitcase would be carried, and walking a set distance while keeping the torso upright and level. It tests the core’s ability to resist tipping sideways, using a single weight as the only equipment.

Equipment Needed

Suitcase Carry needs one dumbbell or one kettlebell, held in a single hand, plus enough open floor space to walk 20 to 50 yards without obstacles. No rack or bench is required, making this an easy exercise to set up anywhere there’s room to walk.

Why Suitcase Carry Matters

Carrying a heavy weight in one hand while walking draws heavily on the trunk’s ability to resist tipping toward the loaded side: the side muscles of the abdomen (obliques) and the deep core muscle wrapping the midsection (transverse abdominis) both work hard against that pull for the entire walk. The side of the hip (gluteus medius) stabilizes the pelvis with each step, the upper back (trapezius) holds the loaded shoulder in place and the forearm (forearm flexors) grips the weight the whole distance. A deep muscle of the lower back (quadratus lumborum) and the muscles along the spine (erector spinae) help hold the trunk level, and the glutes (gluteus maximus) drive each step. Muscular endurance is the main demand, since the anti-tipping brace has to last the length of the walk. Strength and balance matter nearly as much, because the load is heavy and sits off-center while the body moves.

When to Do It

Suitcase Carry works well near the end of a session, often as a finishing exercise for the core and grip after the main strength work is done. It also carries over directly into everyday tasks like carrying a bag or bucket in one hand.

There’s no major population that needs to avoid this exercise, since walking with a single weight carries low general risk. Anyone with a current lower back issue should keep the weight moderate at first, since resisting the sideways pull asks sustained work from the spine’s supporting muscles.

Getting Ready

A few minutes of easy walking warms the whole body before any load gets involved. A short walk holding a light dumbbell in one hand previews the anti-tipping brace and confirms the torso can stay level before adding weight.

Starting with a lighter weight than expected for the first working set, since resisting the sideways pull for a sustained walk feels considerably harder than holding the same weight still, helps settle on the working load for the day.

Step-by-Step Instructions

1. The setup. Pick up the dumbbell or kettlebell in one hand, letting the arm hang naturally at the side.

2. The brace. Brace the core hard, stack the ribcage over the pelvis and set the torso upright and level before taking the first step.

3. The walk. Walk forward in a straight line for the target distance, resisting any lean to either side and keeping the trunk facing straight ahead with no twist.

4. The finish. Set the weight down under control once the distance is covered, then switch sides if training both.

How Many, How Often

Suitcase Carry is dosed by distance or time, since the whole point is sustaining an upright, level torso against a one-sided pull for a stretch of walking.

A torso that stays upright and level through the entire distance matters more here than how far or how heavy the carry is, since leaning away from the loaded side is exactly what removes the anti-tipping challenge this carry is built around.

Modifications and Variations

Suitcase Carry has one alternative, the two-handed carry that balances the load, and one harder version.

As an alternative that balances the load across both hands, Farmer’s Carry carries a weight in each hand at the sides while walking, trading the anti-tipping core challenge for a more straightforward grip and posture demand.

For a harder version, Suitcase Carry with Rotation adds a small, controlled turn of the trunk with each step, which layers a second control task on top of the same level-trunk base. It is worth trying only once the plain carry stays level and facing forward for the full distance.

Common Mistakes to Avoid

Leaning away from the loaded side. It directly defeats the point of the exercise: tilting the torso toward the unloaded side to counterbalance the weight lets the lean, not the core, do the work of balancing the load. Keeping the torso perfectly level, resisting that lean actively, is the entire challenge this carry is built around.

Letting the loaded shoulder rise up toward the ear. Shrugging the shoulder to help support the weight adds tension to the neck and takes work away from the core. Keeping the shoulder relaxed and down keeps the load where it belongs.

Rushing the walk to finish the distance faster. Walking quickly to get through the set trades control for speed, exactly the wrong tradeoff for an exercise built around sustained anti-tipping control. A steady, unhurried pace that keeps the torso level matters more than covering the distance quickly.

Letting a twist creep into the walk. The plain carry has no rotation in it. A trunk that turns toward or away from the weight with each step is giving up part of the bracing the exercise is for.

Loading more than the distance can support. A weight that causes a lean partway through is too heavy for that distance. The first sign of tilting is the cue to set the weight down and rest.

After Your Set

A minute of easy walking without any load settles the whole body before anything else. Standing and reaching one arm overhead while leaning gently away, then switching sides, stretches the side of the torso that just resisted a one-sided pull. Rolling the shoulders through a few slow circles loosens the joints after sustained time carrying an off-center load.

Going Deeper

Suitcase Carry usually sits as a finishing exercise, added after the main strength work of a session since its value comes from sustained anti-tipping control at a moderate load. It pairs naturally with Farmer’s Carry on the same day, covering both a one-sided and a balanced loaded walking pattern in one session.

Progress here tends to stall on the anti-tipping brace before it stalls on grip or arm strength: a lifter who can already carry a heavy load in both hands may still find a single-sided carry humbling purely because resisting a constant sideways pull is its own separate skill from simply gripping and walking. Practicing shorter, lighter one-sided holds without walking, then adding the walk back in once the torso stays level, tends to build that control faster than simply adding weight to a carry that’s already leaning.

Someone new to this exercise generally finds a stable, level torso within the first couple of sessions, and works up to a full working distance and weight somewhere in the three to five week range as the core’s anti-tipping strength catches up to the demand.

How to Know You’re Improving

1. A torso that stays upright and level through the entire walk, with no lean toward either side
2. A loaded shoulder that stays relaxed and down, with no shrug creeping up toward the ear
3. A working weight that stays demanding through the final stretch of the walk
4. A working weight and distance that feel close to even between the left and right side

A torso that stays level through the whole distance, not how far or how heavy the carry gets, is the marker of progress here.

Muscles Worked

• Forearm Flexors (the forearms, holding the entire load in one hand for the whole distance)
• Obliques (the muscles along the sides of the waist, resisting the sideways bend the single load creates)
• Transverse Abdominis (a deep core muscle that wraps around the torso like a corset, bracing against a pull on one side only)
• Gluteus Medius (a smaller glute muscle on the side of the hip, keeping the pelvis level under an uneven load)
• Trapezius (the upper back and neck muscle, stopping one shoulder being dragged down)
• Quadratus Lumborum (a deep muscle of the lower back, holding the pelvis level against the one-sided load)
• Erector Spinae (the muscles running along the length of the spine, keeping the trunk upright)
• Gluteus Maximus (the largest glute muscle, driving each step)

FAQ

How is this different from a regular Farmer’s Carry? The weight is held in one hand only, which creates a sideways pull the core has to resist for the whole walk, unlike the more balanced posture demand of a two-handed carry (see Modifications and Variations above).

Is it normal for this carry to feel much harder on one side than the other? Yes, a difference between sides is common at first and is exactly the kind of imbalance this exercise is good at surfacing. Training both sides for equal distance and weight closes that gap over time.

Why does my lower back feel worked here even though I’m just walking? Resisting a constant sideways pull for the length of the walk asks sustained work from the deep core and lower back muscles, even without any bending or twisting motion (see Why Suitcase Carry Matters above).

Should I keep my head and eyes forward the whole walk? Yes. Looking ahead, and not down at the weight, helps keep the trunk aligned and makes a developing lean easier to feel and correct.

When should I try the version with rotation? Once this carry feels fully controlled over the full distance on both sides, with the trunk level and facing forward.

Should I use the same weight on both sides? Yes, matching the weight between sides is the standard approach, so any difference in how the carry feels reflects a strength gap, not an unequal load.
