Suitcase Carry
Move · Resistance Training · Movement, Typed Supps
Nothing about the carry looks like core training, but the weight is trying to bend you sideways for the entire walk and something has to stop it.
Stage by stage
- Set-up (Single-side load applied): One weight at arm's length creates a sideways bending force on the spine from the moment it leaves the floor.
- During the carry (Obliques hold isometrically): The muscles down the unloaded flank contract steadily to keep the trunk vertical against that moment.
- Each step (Hip abductors resist drop): Single-leg stance asks the gluteus medius to stop the pelvis dropping on the swing side.
- Weeks later (Endurance, not size): Sustained isometric work builds trunk and hip endurance rather than hypertrophy, and shows up as steadier positioning in other lifts.
Muscles trained
- Primary: obliques
- Secondary: abs, forearms, hip abductors, traps
Intensity
5 METs (Carrying 15 pound load (e.g. suitcase), level ground or downstairs).
Time to effect
- Weeks: The ability to resist tipping toward the loaded side improves quickly, and grip endurance on the carrying hand builds fast.
- Months: Oblique and deep core strength build meaningfully, along with grip and trap endurance, often showing up as better resistance to side-bending under load in other lifts.

Common myth
"Suitcase carries and farmer's carries train the same thing." In reality: A farmer's carry balances the load on both sides, so the trunk mostly just resists forward and backward sway. A suitcase carry loads only one side, so the obliques and deep core muscles have to actively resist tipping sideways with every step — it is a genuine anti-lateral-flexion exercise in a way the two-handed version is not.
