Capacity

Grip and carrying: what does holding and carrying weight show?

The short answer

Carrying a heavy weight in each hand tests three things at once: walking under load, holding on, and keeping your posture. In Systematic's Farmer's Carry, the distance you cover shows how much controlled loaded walking you sustained. It is not a measure of walking speed or grip strength on its own, and the carry ends at the first of six stop conditions.

What Systematic recommends

Where to start

  • Hold one equal weight in each hand, approximately 5–15 pounds in each hand, with your feet about hip-width apart and heels in contact with the wall.
  • Maintain contact with the wall through the heels, butt, back, back of the head. Stack the pelvis and ribcage in a neutral position. Keep the midline stable and aligned throughout the hold. Breathe smoothly and effortlessly while maintaining the stacked, rigid midline.
  • Retract the shoulder blades and press them gently toward the wall behind you. Depress the shoulder blades by drawing them downward. Maintain both scapular retraction and depression throughout the hold.
  • Hold the position for 30 seconds. Rest for 30 seconds. Repeat for 3 total cycles. Stop and reassess if you feel pain or discomfort, if you are unable to maintain the wall contact points, or if you can no longer hold the neutral stacked position with smooth, comfortable breathing.

What this capacity is

Systematic calls this capacity loaded locomotion, sustained grip and postural control. The Farmer's Carry combines controlled walking with holding two weights and keeping the trunk, shoulder girdle, spine and pelvis in position under that load.

Distance is the result. It reflects how much controlled loaded walking you sustained and how well you kept moving through space under external load, not walking speed or grip strength or trunk bracing in isolation.

How it is tested

The total load is 50 percent of your body weight, divided equally between two matching weights. Carrying it takes postural and trunk control under a load pressing down through the spine.

End at the first of (1) 120 seconds; (2) either weight dropped or deliberately set down; (3) material upper-back slump/collapse; (4) material or excessive pelvic tilt out of alignment; (5) transition to jogging/running; or (6) the assessment's global safety-stop. Record the feet completed at termination. There are no penalty points.

What the research shows

Muscle-activation and biomechanics studies of the farmer's carry show that walking under load materially changes how the trunk works and how you walk. Work comparing the farmer's walk with unloaded walking found that stride and forces changed, and so did the mechanics of the legs and trunk.

Comfortable walking speed varies by age and sex. A 2023 systematic review of 51,248 apparently healthy adults found that pattern, and a 2011 meta-analysis gives age and sex walking-speed reference values that Systematic uses to scale its provisional carry model. These describe unloaded walking, not carrying.

Grip strength and grip endurance

Grip has been studied in two different ways. The PURE study measured squeeze strength on a hand dynamometer and found it strongly associated with mortality and cardiovascular outcomes across a very large international cohort. That is evidence about squeeze strength, and it gives no norms for holding a weight or hanging from a bar.

Holding on over time is different. A study of climbers doing sustained dead hangs to failure found that, as fatigue built, the work shifted from the finger and forearm muscles toward joints closer to the trunk and the postural muscles. It studied hanging, not carrying.

The evidence

Each cited source is labeled according to how it supports the particular claim on this page. Direct test evidence, underlying-capacity findings and population reference values are distinguished from Systematic-defined protocols and standards. Historical development notes are retained internally rather than presented as public evidence. A study of an underlying capacity is never presented as validation of the Systematic test itself.

  • Direct test evidence

    Ellestad et al. (2024). The Quantification of Muscle Activation During the Loaded Carry Movement Pattern. International journal of exercise science.

    What it found. Muscle-activation and biomechanics work on the farmer's carry shows that walking under load materially changes trunk activation and gait.

    What it does not show. It does not show long-term health outcomes or give age and sex norms.

  • Underlying-capacity evidence

    Winwood et al. (2014). A Biomechanical Analysis of the Farmers Walk, and Comparison with the Deadlift and Unloaded Walk. International Journal of Sports Science & Coaching.

    What it found. Compared with unloaded walking, the farmer's walk changed stride and forces as well as leg and trunk mechanics.

    What it does not show. It does not show that carry distance is the same as walking speed or grip strength.

    What it found. In a review of 51,248 apparently healthy adults, comfortable walking speed varied by age and sex.

    What it does not show. It is about unloaded walking and says nothing about how long a person can carry a load.

    What it found. Gives age and sex reference values for normal walking speed, which Systematic uses to scale its provisional carry model.

    What it does not show. It does not measure carry distance or grip endurance.

    What it found. Dynamometer squeeze strength was strongly associated with mortality and cardiovascular outcomes in a very large international cohort.

    What it does not show. Squeeze strength is not sustained grip under load, and the study gives no norms for carrying or hanging.

    What it found. In climbers hanging to failure, coordination shifted from the wrist and forearm toward joints closer to the trunk and the postural muscles as fatigue built.

    What it does not show. It studied a dead hang in climbers, not carrying, and gives no Farmer's Carry standards or health outcomes.
