Sandbag training might sound niche, but for those who’ve embraced it, the results speak volumes.
Cody from The Stone Circle has spent years mastering the art of lifting bags filled with sand to build muscle and develop what he calls “connected strength.”
His methods have transformed thousands of practitioners, proving that this primal form of training delivers gains that traditional barbells simply can’t replicate.
In a recently recovered training session, Cody breaks down the four foundational sandbag movements that form the backbone of his training philosophy—movements that have helped athletes pack on lean muscle while developing functional, full-body strength.

Why Sandbag Training Demands Respect
Sandbags aren’t just an alternative to conventional weights. They represent a unique training stimulus that exposes weaknesses throughout the entire kinetic chain.
Don’t be intimidated by sandbag. You don’t have to be a huge strong man to get started. Like, I’m just a little guy and just get a sandbag and pick it up and you’ll see. It’s really fun and I just want everyone to have fun with their training and enjoy it cuz that’s what life’s about, right?
Unlike barbells with fixed weight distribution, sandbags shift unpredictably. This instability forces constant micro-adjustments that recruit stabilizer muscles often neglected in traditional training.
Movement One: The Sandbag Row
According to Cody, everything begins with the row. It’s the foundation that makes every other sandbag movement possible.
In my opinion, it’s the foundation of everything. It’s going to train all the muscles you need to be good at lifting sandbags. And in my opinion, a stronger sandbag row means a stronger sandbag everything.
Proper Technique for Maximum Effectiveness
Cody emphasizes specific positioning cues that differentiate sandbag rows from traditional barbell variations:
- Hand placement: Underneath the sides of the bag
- Foot position: Outside the bag for stability
- Hip height: Elevated to create optimal leverage
- Spinal position: Arched lower back with proud chest
The execution involves pulling the bag toward your chest while simultaneously driving feet into the ground. This creates full-body tension that’s impossible to replicate with machines.
Sandbag rows, I think they focus a bit more on the lower back and the hamstrings. Just pretty unique to them.
Grip Variations Matter
Cody notes that individual biomechanics dictate optimal grip strategy. Athletes built for deadlifting can use a false grip with hands completely underneath the bag.
Others benefit from a “claw grip” using primarily fingers. This variation allows for better torso positioning but requires developing significant finger strength over time.
Getting the Bag From Ground to Lap
While not considered one of the “big four,” this transitional movement appears in virtually every sandbag exercise. Mastering it becomes essential for progression.
Cody distinguishes between two primary techniques: the deadlift method and the row method.
In my opinion, starting with the row, it’s made me so much stronger. I was having trouble once I got to the 220 bag when I try to deadlift it up and it was so slow. I’d end up getting it to about here and having to like wiggle it up. Once I started doing the row, focusing on it, it’s like my strength just exploded.
The row technique involves pulling the bag directly to your lap rather than hip-hinging first. This subtle difference creates superior leverage and dramatically improves lifting capacity.
Movement Two: Box Squats (Lap to Chest)
The lap-to-chest movement evolves into something far more potent when performed as box squats. Cody considers this the most comprehensive full-body exercise in sandbag training.
Why Box Squats Trump Standing Variations
Traditional squats require constant tension without rest. This transforms the movement into an endurance challenge where grip often fails before legs reach genuine fatigue.
Box squats allow brief resets between repetitions. You can take a breath, adjust your grip, and refocus on explosive power rather than grinding through metabolic fatigue.
That rest at the bottom lets you reset, makes it so your grip isn’t going to be the limiting factor. So you can just focus on getting those legs, the lower back power off the box.
Momentum Isn’t Cheating
Cody challenges conventional bodybuilding wisdom about strict form. With sandbags, using momentum actually increases training effectiveness.
What I found actually here is if I propel myself off the box, so lean back and throw myself up, what actually ends up happening is that my legs and my back fatigue at an even pace. So now the exercise is hitting more muscle.
This approach allows athletes to complete significantly higher volume. Cody has performed 600 consecutive repetitions using rest-pause methodology—taking 10-20 seconds between reps while keeping the bag in position.
For most practitioners, he recommends 5-30 reps with minimal rest (1-2 seconds) between repetitions.
Optimal Box Height
Cody suggests selecting a box that positions thighs parallel to the ground at the bottom. Below parallel tends to fatigue legs disproportionately. Above parallel requires such heavy loads that the movement becomes impractical.
Movement Three: Bear Hug Carries
Ask sandbag enthusiasts about their love-hate relationship with training, and carries inevitably surface. These deceptively simple movements build extraordinary strength and resilience.
The Ultimate Isometric Back Builder
While carries involve no concentric or eccentric muscle action, they create intense isometric tension throughout the entire posterior chain.
The bear hug carry is basically that for the entire back. So, your upper back is contracting, your lats, in addition to that, there are these tiny shifts. For me, when I started doing the bear hug carry, it just blew up my back.
Beyond muscle development, carries systematically identify and eliminate weaknesses. Initially, biceps typically fatigue first. Once strengthened, grip becomes the limiting factor. Then lower back. Then upper back.
This progression creates balanced, functional strength across all muscle groups simultaneously.
Breathing Strategy Under Pressure
Managing respiration while carrying heavy loads against your torso presents unique challenges. The sandbag compresses your diaphragm, making normal breathing patterns nearly impossible.
Cody recommends positioning the bag slightly below sternum height rather than pressing it high against the chest. This creates space for the stomach to expand during breathing.
If you lower it just a little bit below the sternum height, now you can kind of push your stomach into it. Just this little bit here to here, it’s going to let me go twice as far.
He also suggests taking a deep breath before lifting the bag to your chest, then holding it briefly before beginning slow, controlled breaths. This maintains maximum thoracic expansion against the external resistance.
Practical Applications
Beyond muscle building, carry strength translates directly to real-world scenarios. Being able to transport injured companions, move heavy objects, or simply maintain postural integrity under load represents functional capacity that matters outside the gym.
Movement Four: Sandbag to Shoulder
For many practitioners, this explosive movement represents the pinnacle of sandbag training. It combines power, technique, and athleticism in ways that make it feel less like exercise and more like sport.
For a lot of people, this is the reason to lift sandbags. For me, this is what got me hooked.
The Quadruple Extension Method
Cody’s preferred technique builds on the concept of triple extension (ankles, knees, hips) used in Olympic lifting. He adds thoracic extension as a fourth element, creating maximum power transfer.
The movement sequence:
- Position the bag horizontally
- Wrap arms over the top as high as possible
- Drive hips back as if initiating a jump
- Explosively extend through ankles, knees, hips, and spine
- Throw the bag upward while rotating it
- Slide one arm underneath to catch on the bicep
Cody credits Scottish stone lifter Andy Crawford with inspiring this particular technique.
Landing Position Matters
Proper catching technique protects the bicep tendon. Landing the bag on top of the bicep muscle rather than the forearm eliminates tension on the tendon itself.
This distinction allows athletes to work with heavy loads without the bicep tear risk associated with heavy barbell work.
Multiple Techniques Create Versatility
Unlike barbell movements with strictly defined form standards, sandbag-to-shoulder lifting permits experimentation. Some athletes prefer vertical positioning with a straight hip pop. Others use more rotational power.
That’s the fun of it with the sandbag to shoulder. There are so many different techniques you can do. I think you find the one that just feels fun, you know?
Cody recommends practicing the “throw and catch” as an isolated drill—performing sets of three repetitions to build muscle memory and refine coordination before attempting maximum weights.
The Sandbag Training Philosophy
What separates Cody’s approach from conventional strength training is his emphasis on performance over arbitrary form standards. Using momentum, taking brief rests, and finding techniques that feel natural all serve the ultimate goal: building strength that transfers beyond the gym.
Sandbag training develops what practitioners describe as “connected strength”—the ability to generate and control force through unstable loads that demand coordination between muscle groups.
This approach also naturally regulates training intensity. The bag itself provides immediate feedback. If your technique breaks down or a muscle group fatigues, the movement simply won’t happen.
For those intimidated by the apparent simplicity of lifting bags filled with sand, Cody offers reassurance grounded in experience. Start light, focus on the fundamentals, and let the implement teach you what conventional weights cannot.
The four movements he outlines—rows, box squats, carries, and shoulder lifts—provide a complete training system that builds muscle, eliminates weaknesses, and develops the kind of practical strength that actually matters when you need it most.
