The Science of Suffering: Why Fat Grips + Farmer’s Carries = Unmatched Gains

Your grip is your body’s handshake with the world. Weakness here ripples upward—limp deadlifts, shaky presses, fragile shoulders. Fat grips (2”+ diameter) force your forearms, brachialis, and deep finger flexors to work 30% harder than standard handles. Paired with the Farmer’s Carry—a full-body stability drill—you’re not just building Popeye forearms. You’re forging:

  • A rock-solid core (anti-rotation, anti-flexion)
  • Bulletproof shoulders (scapular stability under load)
  • Grip endurance that laughs at deadlift PRs

Who Should (and Shouldn’t) Attempt This

  • Crave forearms that stretch shirt sleeves
  • Play sports requiring grip dominance (MMA, climbing, strongman)
  • Struggle with deadlift lockouts or shaky overhead presses
  • Want a time-efficient finisher (5-10 minutes max)
  • Have active wrist/elbow injuries (this will aggravate them)
  • Prioritize pure hypertrophy over function
  • Can’t deadlift 1.5x bodyweight (build foundational strength first)

Execution: How to March Without Crumbling

Step 1: Grab fat grip attachments (or wrap towels around dumbbells).
Step 2: Deadlift the weight, squeeze handles like you’re strangling fate.
Step 3: Walk with a proud chest, abs braced, shoulders packed down.
Step 4: Aim for 30-60 seconds of marching. When your grip fails, rest 90 seconds. Repeat 3-5x.


Muscles Worked:

Muscle GroupSpecific Muscles TargetedThe Action
Forearms (Primary)Wrist Flexors (Flexor Carpi Ulnaris, Flexor Carpi Radialis, Palmaris Longus) Wrist Extensors (Extensor Carpi Ulnaris, Extensor Carpi Radialis Longus & Brevis) Brachioradialis Various Grip Muscles (Intrinsic Hand Muscles)Maintaining a crushing grip on the fat grips to prevent the weights from slipping. The thicker diameter significantly increases the challenge to these muscles.
Upper Back & Traps (Primary – Isometric)Trapezius (Upper, Middle, Lower Fibers) Rhomboids Levator ScapulaeWorking isometrically to stabilize the shoulder blades, maintain an upright posture, and prevent the weight from pulling your shoulders down and forward.
Core (Primary – Isometric)Transverse Abdominis (TVA) Obliques (Internal & External) Rectus Abdominis Erector SpinaeEngaging isometrically to stabilize your torso, resist lateral flexion (side-to-side bending) caused by the unilateral load shift with each step, and prevent excessive spinal movement.
Shoulders (Secondary – Isometric)Deltoids (Anterior, Lateral, Posterior)Working isometrically to stabilize the shoulder joint and support the weight being held at your sides.
Legs (Secondary – Dynamic)Quads Hamstrings Glutes CalvesWorking dynamically to propel you forward during the walk, maintaining balance and stability under load.
Lats (Secondary – Isometric)Latissimus Dorsi (Lats)Assisting in stabilizing the shoulders and preventing the arms from being pulled away from the body by the heavy load.

Now, let’s explore some progressions to keep challenging yourself:

ProgressionThe AdjustmentIncreased Challenge/FocusA Different Angle
Increase the WeightUse heavier dumbbells, kettlebells, or specialized farmer’s carry implements.Directly increases the load your entire body needs to stabilize and carry.The most straightforward way to build overall strength and grip endurance.
Increase the DistanceCarry the same weight for a longer distance.Primarily challenges grip endurance, core stability over time, and cardiovascular fitness under load.Turning it into more of a loaded march, testing your staying power.
Increase the Duration (Timed Carries)Carry the weight for a set amount of time rather than a specific distance.Similar to increasing distance, emphasizing endurance and mental fortitude.Holding on against the clock, pushing your limits of sustained effort.
Uneven Loads (Unilateral Farmer’s Carry with Fat Grip)Carry a heavy weight in only one hand with a fat grip.Dramatically increases the demand on your core to resist lateral flexion and rotation.A significant challenge to your anti-lateral flexion strength and balance.
Faster Walking SpeedAttempt to carry the weight at a brisker pace.Increases the dynamic stability demands on your core and legs.Adding a speed element, requiring more active stabilization.
Obstacle Course CarryIncorporate simple obstacles like walking over low boxes or around cones while carrying the fat grip weights.Challenges your balance, coordination, and ability to maintain stability while navigating varied terrain.Adding a functional movement component, mimicking real-world scenarios.
Overhead Farmer’s Carry with Fat Grips (Advanced)Press the fat grip weights overhead and walk for a short distance.Significantly increases the demand on your shoulders, upper back, and core to stabilize the load overhead while walking.An advanced progression requiring substantial shoulder stability and core strength.
Fat Grip Pinch Carries (Pinch Blocks or Plates)Instead of a full grip, pinch thick plates or specialized pinch blocks with fat grips attached and carry them.Severely increases the grip challenge, specifically targeting pinch strength.A focused assault on a different aspect of grip strength.

The Trade-Offs: Pros vs. Cons

ProsCons
Forearms that look CNC-machinedGrip fatigue can limit other lifts
Core stability on steroidsNot ideal for pure mass seekers
Fixes “office posture” (upright!)Requires equipment (fat grips)
Time-efficient (10 mins = done)Brutal on calluses

You’ve got the basics down—now let’s dig into the gritty details most lifters overlook. These six Q&As tackle the unspoken questions, the “what-ifs,” and the secrets to turning this exercise from a grind into your advantage.

Q1: Can I use fat grips for other exercises to boost carryover?

Absolutely. Attach them to pull-ups, rows, or deadlifts for compound grip challenges. Just avoid overuse—your forearms need recovery to grow.

Q2: How does this compare to traditional forearm workouts?

Static holds (like plate pinches) build raw strength. Fat grip carries add dynamic tension and full-body coordination—think “functional hypertrophy.”

Q3: Will this help with elbow tendonitis?

Surprisingly, yes—if you’re pain-free. Light carries improve blood flow and tendon resilience. But heavy loads? Proceed with caution.

Q4: What’s the ideal floor surface for max gains?

Uneven terrain (grass, gravel) forces stabilizer muscles to work harder. Save smooth floors for beginners or deload weeks.

Q5: Can desk jockeys benefit without bulking up?

Yes. Light carries combat “typing hands” and improve posture. Think endurance over mass—go lighter, walk longer.

Q6: Why do strongmen swear by this for grip contests?

It mimics real-world demands: sustained crushing strength under fatigue. No gadget replicates that primal, time-tested stress.

Final Word: “The farmer’s carry doesn’t care about your excuses. It only cares if you quit.” – Eugene Thong, CSCS.
