If Your Shoulders Round Forward Three Steps Into Carrying Two Grocery Bags or Moving Boxes
Walking out of a big-box store with two grocery bags loaded in each hand, you probably stand tall for the first few steps, but by the time you reach the middle of the parking lot you notice your shoulders have already rounded forward and your head has drifted ahead of your body without you meaning it to. Carrying a moving box up the stairs with both hands feels similar. You start with your chest up, but by the third flight your back is hunched, your arms are shaking, and the strength in both hands is fading at the same time.
This is a different kind of failure than the side-ache you get carrying a bag in just one hand. With equal weight in both hands, there's no reason for your body to tip sideways, yet you still can't hold on for long — your upper body collapses forward and both hands lose their grip at nearly the same moment. You've built front-to-back trunk stability with planks and grip strength with a hand gripper, so why does everything fall apart this fast in real life?
A farmer's carry (also called a farmer's walk) means holding equal weight in each hand and walking a set distance, and it trains two things at once: "posture endurance" — the ability to stay upright without your trunk collapsing forward — and "grip endurance" — holding on with both hands at the same time without letting go. The suitcase carry covered in an earlier guide loads only one hand and trains anti-lateral flexion, resisting the pull that tips your spine sideways. Because a farmer's carry splits the load evenly between both hands, the left-right torque cancels out, and instead of resisting a sideways pull, you're resisting a straight-down compressive force and the tendency for your upper body to collapse forward under it. These two exercises train different things, so here's how to start a farmer's carry safely and a stage-by-stage plan to build it up.
Why Holding Equal Weight in Both Hands Tests Grip and Posture at the Same Time
What Cancels Out and What Shows Up Instead: A Straight-Down Compressive Load
A suitcase carry, with weight in just one hand, creates torque that pulls the spine sideways. A farmer's carry, with equal weight in both hands, mostly cancels that left-right torque out. What replaces it is the combined weight of both loads pressing straight down through the spine as a compressive force. The body's most common response to this pressure — in the name of "protecting the back" — is to round the upper back and let the shoulders drop forward. But that forward collapse actually distributes the load unevenly across the spinal segments and worsens the arm angle needed to hold the grip. Keeping the ribcage stacked directly over the pelvis while the upper back muscles — the erector spinae, mid-trapezius, and rhomboids — stay continuously engaged to hold the trunk upright: that's the "posture endurance" a farmer's carry tests.
A study by McGill, McDermott, and Fenwick (2009), published in the Journal of Strength and Conditioning Research, compared several strongman events — the farmer's walk (symmetrical), the suitcase carry (one-sided), and an offset carry — measuring spinal compressive load, trunk muscle EMG activity, and spinal motion. Among the carry variations compared, the farmer's walk produced the highest spinal compressive load but the smallest lateral bend angle, with a pattern of the front and back trunk muscles (abdominals and erector spinae) co-contracting together to keep the spine rigid. That said, this study was conducted on a small number of trained strongman competitors, so applying the exact figures to the general population or a rehab setting calls for caution — it's best read as a reference for the underlying direction: symmetrical loading mainly trains resistance to compression, while asymmetric loading mainly trains anti-lateral flexion.
Why Grip Is Twice as Hard
With a suitcase carry, you can switch the weight to your other hand when one gets tired. With a farmer's carry, both hands have to hold on for the exact same duration at the same time — there's no resting hand. That doesn't just mean the total grip demand doubles; it also means the moment one hand's grip gives out first, the other hand is suddenly left holding the entire load — a genuinely risky moment. This gives the farmer's carry a distinct characteristic: the weaker hand's grip sets the limit for the entire set.
A review by Bohannon (2019), published in Clinical Interventions in Aging, compiled research repeatedly linking grip strength to physical function, falls, hospitalization, and mortality in older adults, concluding that grip strength deserves to be called an "indispensable biomarker." Most of the research this review examined was observational or focused on older adults, so it doesn't directly prove that training like a farmer's carry actually improves these outcomes. Still, given that the ability to carry belongings in both hands reflects overall muscle strength, balance, and neuromuscular control combined, there's ample reason to functionally train two-hand grip endurance.
What Changes Once Walking Is Added to a Static Hold
Unlike a static hold performed standing still, a farmer's carry done while walking shifts the pelvis and ribcage slightly forward and back with every step, moving the center of mass. Your body has to keep re-finding the ribcage-pelvis alignment throughout that motion, so a farmer's carry trains not just holding endurance but also the dynamic control needed to reset posture with every stride. As a set goes on, the upper back muscles tend to fatigue first, and that's exactly the point where the shoulders start to round forward — a useful marker of whether that day's training intensity was appropriate.
Signs You Should Not Start the Farmer's Carry Yet
If any of the following applies to you, see a medical professional before starting the lifting and walking techniques described below. A farmer's carry places substantial compressive force on the spine, so it calls for a wider range of caution than the suitcase carry.
- Numbness or a pulling sensation radiating down one leg when bending or lifting weight: this may indicate a disc pressing on a nerve, in which case a medical visit takes priority over self-directed training.
- A bulge or lump you can feel or see in the abdomen or groin area when bearing down: this could be a hernia, and the sharp rise in intra-abdominal pressure from lifting a heavy weight in both hands can worsen the condition, so see a surgeon first.
- A diagnosis of osteoporosis or a history of a vertebral compression fracture: among carry variations, the farmer's carry places one of the largest straight-down compressive loads on the spine, so if bone strength is reduced, confirm a safe starting weight with a medical professional first.
- Lumbar spinal stenosis where extending or standing the back up straight causes numbness or a pulling sensation down the leg: a farmer's carry requires holding an upright, extended trunk posture for an extended time, and for some people that posture itself provokes stenosis symptoms, so see a doctor before starting.
- A wrist or shoulder fracture or ligament injury within the past 3 months, or active numbness from carpal tunnel syndrome: gripping and holding weight in both hands can place direct strain on the affected area.
- Uncontrolled high blood pressure or a heart condition that limits breath-holding or straining movements: the bracing and breath control involved in a farmer's carry can affect blood pressure, so check with your doctor first.
- A feeling of your abdomen separating or bulging forward under intra-abdominal pressure from mid-pregnancy onward (possible diastasis recti): discuss appropriate weight limits with an OB-GYN or a women's health physical therapist first.
- Dizziness or balance impairment that raises fall risk while walking: carrying weight in both hands makes it harder to use your arms for balance, raising the risk of a fall.
If none of the above applies and your goal is simply to functionally build grip and posture endurance, go ahead and start with the sequence below. If pain in your back or wrist keeps recurring after 3-4 weeks, have your form evaluated.
The Farmer's Carry Done Right: It's Decided the Moment You Grip and Set Your Shoulders
As with any loaded carry, what's already decided before your walking posture even matters is the moment you first lift the weight. If your back is already rounding or your bracing is already gone the instant you pick it up, that broken alignment carries through the entire walk.
Positioning Before You Lift
- Set two containers of equal weight — water jugs or bags loaded with books — side by side next to each foot, as close to your body as possible.
- Lower down using a hip hinge to grip both handles at the same time. Picking up one side first and the other second creates a left-right imbalance in that instant, so aim to grip and stand up with both hands together whenever possible.
- Wrap your whole hand around each handle and lock your thumb over your fingers in a full "crush grip," matching the grip on both sides.
The Lift and Shoulder Position
Right before standing up with leg strength, brace first by pushing your abdominal wall outward from the inside. Hold that tension as you extend your legs to stand, lifting your chest slightly and setting both shoulder blades gently back and down, as if pinning them in place. With the suitcase carry, the key check was "are both shoulders level?" With the farmer's carry, the key check is "are both shoulders staying pinned back instead of rounding forward?" Right after standing, check that the bottom of your ribcage is stacked directly over your pelvis and that your head hasn't drifted forward — aim for a feeling of the crown of your head being gently pulled toward the ceiling.
Common Mistakes
- Rolling the shoulders forward as the weight gets heavier: when it gets hard, the instinct is to round the back to take the weight "the easy way," but doing so robs the upper back muscles of the chance to work, reducing the posture-endurance training effect and often leading to neck and shoulder pain. Reset partway through a set by lifting the chest slightly.
- Poking the chin forward: as grip fatigue sets in, the head tends to drift forward unconsciously, throwing off neck alignment. Keep your eyes forward and your chin gently tucked.
- Holding your breath: bracing and holding your breath are not the same thing. You should be able to keep your abdomen braced while still taking short breaths — that's the normal state.
Staying Upright While You Walk: Stride and Upper-Body Sway
Even with a solid brace and shoulder set in place, the wrong walking pattern will break down your form by the end of a set. Where the suitcase carry is about not tipping sideways, the farmer's carry is about not rounding forward the longer you walk.
Shorten Your Stride Slightly and Keep a Steady Rhythm
Shorten your stride by roughly 10-15% from normal and keep short, stable steps, and the front-to-back sway in your upper body with each stride decreases. Point your toes straight ahead and keep your gaze 3-4 meters in front of you, walking at a steady, even rhythm. The more irregular the rhythm, the faster your upper body tires from having to resist that unevenness.
Posture Before Speed
The instinct is to walk fast and get it over with, but the faster you go, the wider the front-to-back sway of the load becomes with each step, tiring the upper back muscles faster. Start at roughly 70-80% of your normal walking speed to get a feel for keeping your shoulders from rounding, then gradually pick up the pace once your form is stable.
Set Check-In Points Along the Way
The longer the distance, the harder it becomes to notice your own form breaking down. Build a habit of doing a quick check — "are my shoulders still back, is my chin still tucked" — every 10 meters, or every time you pass a landmark, so you catch it and reset before your posture fully collapses.
Common Mistakes
- Speeding up your steps in the second half of a set: wanting to finish quickly tends to speed up your steps, which increases upper-body sway right along with it. The harder it gets, the slower and shorter your steps should become instead.
- Carrying the weight out in front of your body: as your arms tire, the handles tend to drift out in front of your torso, which increases the forward pull on your upper body and speeds up rounding. Keep the handles tracking along the side of your body, right next to the outer line of your thighs.
A 6-Week Plan: From the Basic Pattern to a Static Hold
Understanding the bracing and shoulder-set technique intellectually doesn't mean much if you jump straight into a heavy weight over a long distance — your back will likely round or your grip will give out within a few days, and it's easy to lose interest. The program below starts by building the basic pattern with a light weight, then gradually raises the weight and grip difficulty, and finishes with a static hold — standing still rather than walking — that pushes grip endurance to its limit.
Contraindications to Check Before Starting
Consult a medical professional before starting the program below if any of the following apply to you.
- Active disc herniation currently causing leg numbness or altered sensation
- A diagnosed hernia, or a bulging sensation when intra-abdominal pressure rises
- Osteoporosis or a history of vertebral compression fracture
- Lumbar spinal stenosis where extending the back causes leg numbness or a pulling sensation
- Wrist or shoulder surgery or a fracture diagnosis within the past 3 months
- Uncontrolled high blood pressure, arrhythmia, or another condition limiting straining movements
- Mid-pregnancy onward, or suspected diastasis recti — discuss weight limits separately with a medical professional
Stage 1: Build the Basic Pattern With a Light Weight (Week 1)
Starting position: Place two containers of equal weight — water jugs or bags loaded with books — side by side beside each foot, hinge at the hips to lower down, and grip a handle in each hand at the same time.
Movement: Brace first, then stand up using leg strength, lifting your chest slightly and pinning both shoulder blades back. Walk 10-15m with a shorter-than-normal stride.
Breathing: Keep the brace in place while taking short breaths in through the nose and out through the mouth. Be careful not to hold your breath.
Sets and frequency: 3 round trips of 10-15m, 3-4 times per week.
Common mistake to correct: Letting the shoulders round forward the moment the weight is lifted is common. Build the habit of pausing for 3 seconds in the standing position before walking to check shoulder alignment.
Stop signal: Stop immediately and consult a medical professional if you feel a sharp pain in the center of the back or a sharp pain in the wrist while walking.
Stage 2: Increase Weight and Extend Distance (Weeks 2-3)
Starting position: Prepare two weights roughly 15-20% heavier than Stage 1.
Movement: Brace and walk while staying aware the entire time of whether your shoulders are staying pinned back. Check your form briefly every 10m and extend the distance to 20-25m.
Breathing: Keep the same rhythm as Stage 1, and check yourself for unconsciously holding your breath as the grip fatigues in the later part of the walk.
Sets and frequency: 3 round trips of 20-25m, 3-4 times per week.
Common mistake to correct: As the distance grows, the chin tends to poke forward in the second half. Keep your eyes fixed forward and hold a slightly tucked chin throughout the set.
Stop signal: Pain appearing in the lower back rather than the upper back, or a grip that noticeably gives out faster with each set, means the weight should drop back to Stage 1.
Stage 3: Raise the Grip Difficulty (Weeks 4-5)
Starting position: Use the same weight as Stage 2, but wrap a thick towel around each handle to increase grip diameter, or use a thick round object — like a heavy pipe or a weighted bat handle — instead of a bag with a thin strap.
Movement: Walk the same distance as Stage 2, focusing on the sensation of gripping the thicker handle. Since your grip fatigues faster than usual, watch that your grip doesn't give out before your posture does.
Breathing: Keep the same rhythm as Stage 2.
Sets and frequency: 2-3 round trips of 20-25m, 3 times per week.
Common mistake to correct: When gripping gets hard, some people bend the wrist to hook the handle instead of gripping it fully, which places unnecessary strain on the wrist. Keep the wrist straight and maintain the sensation of wrapping the whole hand around the handle.
Stop signal: Stop and reduce grip difficulty immediately if numbness or sharp pain appears on the inside of the wrist, and see a doctor if it keeps recurring.
Stage 4: Extend Grip Limits With a Static Hold (Week 6 Onward)
Starting position: Stand holding whichever weight combination from Stage 3 you handled comfortably, one in each hand.
Movement: Stand still, without walking, maintaining shoulder position and bracing for as long as possible. The moment your grip starts to give out marks the end of that set.
Breathing: Keep a short, steady rhythm, and consciously resist the urge to hold your breath as the hold time increases.
Sets and frequency: 3 sets timed for maximum hold, 2 minutes of rest between sets, 2 times per week.
Common mistake to correct: Shrugging the shoulders up to help support the weight in an effort to hold longer is a common compensation. Keep the shoulders pressed down and rely purely on the grip and upper back muscles to hold the position.
Stop signal: If your hold time drops noticeably compared to the previous session, or wrist or back pain lingers into the next day, reduce the weight and take a recovery period.
Week-by-Week Progression Plan
| Week | Training Focus | Style / Weight | What to Check |
|---|---|---|---|
| Week 1 | Build the basic pattern: bracing and shoulder alignment | Equal weight in both hands, roughly 8-10% of body weight per hand | Whether the shoulders are pinned back right after standing |
| Weeks 2-3 | Extend weight and distance, hold posture through the second half | 12-15% of body weight per hand, distance 20-25m | Whether the chin stays tucked even late in the set |
| Weeks 4-5 | Raise grip difficulty (thicker handles) | Same weight as Weeks 2-3, larger handle diameter | Whether the wrist stays straight rather than bending |
| Week 6 onward | Extend grip limits with a static hold | Whichever combination felt comfortable, timed for maximum hold | Whether hold time holds steady or improves versus the previous session |
The standard for progressing is "do my back and wrist still feel fine the day after finishing that weight and distance." If soreness still lingers a day later, repeat the same stage for a few more days before increasing weight or distance.
Near-Infrared Conditioning for Upper Traps and Forearm Recovery After Training
Starting a farmer's carry can bring on unfamiliar soreness in the upper back (mid-trapezius and rhomboids) and both forearms. These are muscles that planks and hand grippers rarely engage much, so this is a normal response to newly working them — but this same soreness is also what causes some people to give up on training partway through. Some people use near-infrared (NIR) conditioning as a post-training relaxation routine during this period — it's worth understanding accurately that this is not a treatment for muscle soreness or joint problems, but a wellness routine meant to help you keep training consistently.
The Basic Idea
- Cellular metabolism support: near-infrared wavelengths are understood to reach tissue beneath the skin and interact with cellular energy metabolism, an area studied in the field of photobiomodulation.
- Local blood flow changes: a warm sensation along with a temporary local increase in blood flow at the treated area is commonly reported.
- Post-training relaxation: used to support the relaxation of the upper back and forearm muscles that get sore after farmer's carry training.
Many people find themselves using this relaxation routine nearly every day during the first 1-2 weeks, which coincides with when soreness peaks as the body adapts to a new posture pattern. Once the pattern is established and soreness eases from week 4 onward, cutting back to 2-3 times a week is perfectly fine.
How to Work It Into Your Routine
If you use a near-infrared healthcare device like the CIRIUS LED Pro or Compact, keep the following in mind. This is a conditioning support routine, not a diagnostic or treatment procedure for muscle or joint conditions.
- Keep the device 5-10cm from your skin, aiming it at the upper back (trapezius area) and forearms.
- Apply it for 10-15 minutes right after farmer's carry training.
- Using it consistently as a recovery routine once you reach the static hold stage can help you keep training consistently.
- It does not replace existing treatment or a medical professional's instructions — if pain persists or numbness appears, be sure to consult a specialist alongside it.
Choosing a Weight and Matching Both Sides: Details That Prevent Injury
What to Use for Weight
- Split several 2-liter water bottles evenly between two bags with handles, or use two identically sized detergent jugs. Even a small difference in weight between the two sides will pull your body toward the heavier one without you realizing it, so measure both sides with a scale or measuring cup before you start.
- If you have dumbbells or a kettlebell at home, two of equal weight work fine, but the whole point of this training is that it requires no special equipment to begin. Maintaining your brace and shoulder alignment matters far more than which weight you choose.
- Bulky items like moving boxes are more about handle placement than weight. If there's no handle, wrap a rope or strap around the box to create one so your grip doesn't shift around.
Gauge Your Starting Weight by Body Weight, and Always Match Both Sides
Weighing everything on a scale every time is tedious, so use roughly 8-10% of your body weight per hand (about 5-6kg per hand for a 60kg person) as your starting point. Since a farmer's carry only serves its purpose when both sides carry exactly the same weight, get in the habit of measuring water with a measuring cup or checking each container on a scale individually.
Footwear and Flooring
Wear non-slip-soled shoes and train on flat ground with clear visibility. With weight in both hands, the containers will brush past your legs as you walk, so make sure you have enough width to avoid hitting your ankles or shins.
Training Outdoors
If you use an outdoor space like a park or parking lot, avoid uneven ground, and start with a short, straight stretch of about 20-30m before extending the distance once you're comfortable.
Correcting Common Misconceptions
"It doesn't matter which order you learn the suitcase carry and the farmer's carry in"
→ That's not accurate. Because the farmer's carry cancels out left-right torque, it's a comparatively lower-risk, symmetrical exercise that's well suited to learning the basic pattern — bracing, grip, and posture. Once that foundation is in place, moving on to the one-sided suitcase carry lets you train anti-lateral flexion as a separate skill. The two exercises serve different purposes, and reversing the order can expose you to a more demanding asymmetric load before your fundamentals are solid.
"Heavier weight always means better posture-endurance training"
→ Increase the weight while walking with a rounded back and you end up stimulating the wrong compensatory muscles in the shoulders or neck instead of the upper back. The moment your shoulders start rounding forward is your personal ceiling — walking below that weight while maintaining alignment produces a better posture-endurance training effect.
"Training grip alone with a hand gripper is enough without a farmer's carry"
→ A hand gripper is effective for training momentary peak grip strength, but the endurance grip needed to hold on with both hands at once while moving is a separate ability. Since this endurance grip gets used far more often in real life — carrying belongings in both hands — training both together is the ideal approach.
"It's a back-loading exercise, so anyone with a weak back should avoid it entirely"
→ It's true that a farmer's carry places compressive force on the spine, but that's a different kind of demand than the strain that comes from bending and twisting the back. A vertical, straight-down compression on an upright spine, with proper bracing, is manageable for most people. There are exceptions, though, such as the spinal stenosis and osteoporosis cases covered earlier — if either applies to you, be sure to check with a medical professional first.
