Key takeaways
- Farmer carries (bilateral, symmetrical) build grip strength and general trunk stability; they’re lower-demand and can be done frequently.
- Suitcase carries (unilateral, asymmetrical) demand anti-rotation core tension and build real trunk stiffness; they’re higher-demand and require careful load and frequency management.
- Load farmer carries at 60–70% of single-arm deadlift max; suitcase carries at 50–60%.
- Duration: 30–90 seconds per set or per side. Longer carries (>2 minutes) shift focus to grip endurance.
- Frequency: farmer carries 3–5× per week; suitcase carries 2–4× per week, never on consecutive days at high load.
- Suitcase carries should come earlier in a session than farmer carries if both are programmed together.
- Progression is load-first, then duration, then frequency—not all three at once.
The difference: farmer vs. suitcase carry
Farmer carries use symmetrical load (kettlebell in each hand or same weight on each side). Your trunk stays centered. Grip and general postural endurance are the limiting factors.
Suitcase carries use unilateral load (one kettlebell, one side). Your core must resist lateral flexion and rotation. The loaded side pulls your torso down and sideways; your anti-rotation muscles must brace to keep you upright and square.
For trunk strength specifically, suitcase carries are the primary tool. Farmer carries are excellent for warm-up, finisher, or grip-building, but they don’t demand the same anti-rotation tension.
Both improve posture and resilience. Both are safe when load and form are correct. The difference is specificity: suitcase carries train the exact stability your spine needs under asymmetrical load.
Load selection and starting points
Farmer carry load:
Start with 60–70% of your single-arm deadlift max, or pick a kettlebell you can hold for 90 seconds without your grip failing. If you don’t know your deadlift max, use a kettlebell that feels moderately heavy but not crushing—something you could carry across a room without dropping.
Suitcase carry load:
Start with 50–60% of single-arm deadlift max. This is lighter than farmer carries because the anti-rotation demand is higher. A weight that feels “moderate” in a farmer carry will feel significantly heavier in a suitcase carry.
Load progression rule:
Increase load by one kettlebell size (4–8 kg) only after you can complete all prescribed sets and reps at the current weight with perfect form (shoulders level, no torso tilt, no compensation). Do not add load and duration in the same week.
Duration, distance, and time under tension
Time-based carries (recommended for trunk strength):
– Beginner: 30–45 seconds per side (suitcase) or per set (farmer).
– Intermediate: 45–75 seconds per side or set.
– Advanced: 60–90 seconds per side or set.
Beyond 90 seconds, you’re training grip endurance and metabolic capacity more than trunk strength. If your goal is anti-rotation stiffness, stay under 90 seconds and use heavier load.
Distance-based carries (alternative):
Walk 40–60 meters (farmer) or 20–40 meters per side (suitcase). Useful if you have a defined space but no timer. Distance and time are interchangeable; pick whichever fits your environment.
Rest between sets:
– Farmer carries: 60–90 seconds (grip recovery).
– Suitcase carries: 90–120 seconds (core and grip recovery).
Do not rush. Fatigue degrades form, and poor form in a suitcase carry teaches your spine bad habits.
Sets, reps, and frequency
Farmer carries:
– 3–5 sets of 45–90 seconds, 2–3 times per week.
– Can be done daily at light load (40–50% max) as a warm-up.
– Excellent as a finisher after strength work.
Suitcase carries:
– 3–4 sets of 30–60 seconds per side, 2–4 times per week.
– Never on consecutive days at high load (>60% max).
– Alternate sides within a session (e.g., right side, rest, left side, rest) or across sessions (Monday right, Wednesday left, Friday both).
Weekly volume rule:
Total carry volume (sets × duration) should not exceed 15–20 minutes per week for suitcase carries. Farmer carries can be higher (20–30 minutes) because they’re symmetrical and lower-demand.
| Movement | Load (% max) | Duration | Sets | Frequency | Notes |
|---|---|---|---|---|---|
| Farmer carry | 60–70% | 45–90 sec | 3–5 | 2–5×/week | Symmetrical, lower demand, can be frequent |
| Suitcase carry | 50–60% | 30–60 sec/side | 3–4 | 2–4×/week | Unilateral, high anti-rotation demand, needs recovery |
| Farmer carry (light) | 40–50% | 30–60 sec | 2–3 | Daily | Warm-up or finisher only |
Progression pathways
Phase 1: Load establishment (weeks 1–3)
– Pick a load you can carry for the full duration with perfect form.
– Do 3 sets, 2–3 times per week.
– Goal: establish baseline and groove movement pattern.
Phase 2: Duration extension (weeks 4–6)
– Keep load the same.
– Add 10–15 seconds to each set (e.g., 45 sec → 60 sec).
– Maintain 2–3 sessions per week.
– Goal: build time under tension without adding load.
Phase 3: Load increase (weeks 7–9)
– Increase load by one kettlebell size (4–8 kg).
– Reset duration to 30–45 seconds per side (suitcase) or per set (farmer).
– Maintain frequency.
– Goal: drive strength adaptation.
Phase 4: Frequency increase (weeks 10–12)
– Keep load and duration constant.
– Add one session per week (e.g., 2× → 3× per week).
– Goal: build work capacity and consistency.
Then cycle back to Phase 2 or repeat Phase 3. Do not increase load, duration, and frequency simultaneously.
Common programming mistakes
Mistake 1: Suitcase carries too frequently at high load.
The anti-rotation demand is high. Doing suitcase carries 5–6 times per week at 60%+ load causes cumulative spinal fatigue and poor form. Limit to 3–4 times per week at high load, or use lighter load (40–50%) on extra days.
Mistake 2: Ignoring form breakdown.
If your shoulders start to tilt, your ribcage flares, or you lean away from the loaded side, stop the set. Fatigue teaches compensation. A 30-second set with perfect form beats a 60-second set with a tilted spine.
Mistake 3: Progressing all variables at once.
Adding load, duration, and frequency in the same week is unsustainable. Pick one variable per 2–3 week block. Load first, then duration, then frequency.
Mistake 4: Farmer carries only.
Farmer carries are excellent but don’t demand anti-rotation tension. If trunk strength is your goal, make suitcase carries your primary tool and use farmer carries as a warm-up or accessory.
Mistake 5: Carries on tired legs.
If your legs are fatigued from a heavy lower-body session, your core stability suffers. Program carries earlier in the session or on separate days from heavy squats or deadlifts.
Session integration and placement
Warm-up (5–10 minutes before main work):
Light farmer carries (40–50% load, 30–45 seconds, 2 sets) prepare your grip and core without fatiguing you.
Main work (after strength, before conditioning):
Suitcase carries at moderate-to-heavy load (50–60% max, 3–4 sets, 45–90 seconds per side) when you’re fresh. This is where you build anti-rotation strength.
Finisher (last 5–10 minutes):
Farmer carries at moderate load (60–70% max, 3 sets, 60–90 seconds) or light suitcase carries (40–50% max, 2–3 sets, 45 seconds per side) to accumulate volume without compromising form.
Standalone session:
Carries alone (farmer + suitcase, 15–20 minutes total) work well 1–2 times per week. Example: 3 sets of farmer carries, rest 2 minutes, 3 sets of suitcase carries (alternating sides).
Who this is for
Ideal candidates:
– Adults training for general fitness, strength, or athletic resilience.
– People with desk jobs or poor posture who need core stability work.
– Lifters adding anti-rotation training to a barbell program.
– Anyone building a home gym with minimal equipment.
– Intermediate and advanced kettlebell users.
Proceed with caution:
– Recent spinal injury or chronic back pain: consult a healthcare provider before heavy suitcase carries. Light farmer carries are usually safe.
– Severe grip weakness: start with farmer carries only; add suitcase carries once you can hold a moderate load for 60 seconds.
– Shoulder instability: farmer carries are safe; suitcase carries may aggravate asymmetrical load. Get clearance first.
Not ideal for:
– Absolute beginners with no kettlebell experience: learn basic movement patterns (swing, goblet squat, Turkish get-up) first.
– People with active shoulder or elbow pain: carries load the shoulder and grip heavily.
FAQ
Should I do farmer carries and suitcase carries in the same session?
Yes, but sequence matters. Farmer carries (bilateral, symmetrical) work well as a warm-up or finisher. Suitcase carries (unilateral, anti-rotation) demand more core tension and should come earlier if trunk stability is your goal. Do farmer first, suitcase second, or separate them by 48 hours if you’re emphasizing suitcase load.
How long should a single carry last?
Start with 30–45 seconds per side (suitcase) or per set (farmer). Advance to 60–90 seconds as grip and core endurance improve. Beyond 2 minutes, you’re training metabolic endurance more than trunk strength; keep carries under 2 minutes unless grip work is your primary goal.
Can I do carries every day?
Farmer carries (bilateral) can be done daily or near-daily at moderate load because they’re symmetrical and lower-demand on the spine. Suitcase carries (unilateral) should not exceed 3–4 times per week at high load; the anti-rotation demand and spinal asymmetry require recovery. Alternate sides or use lighter load on consecutive days.
What load should I start with?
Farmer carry: use 60–70% of your single-arm deadlift max, or start with a kettlebell you can hold for 90 seconds without grip fatigue dominating. Suitcase carry: use 50–60% of single-arm deadlift max. If unsure, pick a weight that lets you stand tall, brace your core, and resist tilting for the full duration without compensation.
Do carries build muscle or just endurance?
Carries build both, depending on load and duration. Heavy carries (>70% max) for 30–60 seconds build strength-endurance and trunk stiffness. Lighter carries (40–60%) for 90+ seconds build muscular endurance and grip resilience. For trunk strength, prioritize heavier load and shorter duration.
How do I know if I’m doing suitcase carry correctly?
Your shoulders should stay level and square. Your ribcage should not flare or lean away from the loaded side. Your core should feel braced, not loose. If your torso tilts or your opposite shoulder hikes, reduce load or duration. Video yourself from the front to check alignment.
Can carries replace other core exercises?
Carries are excellent for anti-rotation and isometric trunk stability, but they don’t replace dynamic core work like dead bugs, bird dogs, or pallof presses. Use carries as a foundation and add 1–2 dynamic core exercises per week for complete trunk development.
