The Atlas stone, a behemoth of concrete and a symbol of raw strength, is a staple in strongman competitions worldwide. Lifting these massive spheres is a test of not only brute power but also technique, grip, and mental fortitude. But the burning question for many, both aspiring strongmen and curious onlookers, remains: how much does an Atlas stone actually weigh? The answer, as you might suspect, isn’t a simple one. Let’s delve into the world of Atlas stones, exploring the variables that affect their weight, the common sizes used in competition, and everything else you need to know about these impressive feats of concrete engineering.
The Variable Weight of Atlas Stones
One of the first things to understand about Atlas stones is that they don’t come in standardized weights. Unlike barbells or dumbbells, which are manufactured to precise specifications, Atlas stones are often custom-made, leading to significant variations in their weight. This variability adds to the challenge and excitement of strongman competitions.
The weight of an Atlas stone is primarily determined by its size (diameter) and the density of the concrete used. While strongman organizations may have guidelines for stone weights in certain events, these are often flexible, and the specific weight of a stone can vary from competition to competition. Even within the same competition, different weight classes may use stones of varying sizes.
Factors Influencing Atlas Stone Weight
Several factors contribute to the final weight of an Atlas stone:
Diameter: The larger the diameter of the stone, the more concrete it contains, and therefore, the heavier it will be. This is the most significant factor affecting the weight.
Concrete Density: The density of the concrete mix can vary depending on the aggregate used (sand, gravel, etc.) and the amount of cement. A denser concrete mix will result in a heavier stone for a given diameter.
Fillers and Additives: Some stone makers might add fillers or additives to the concrete mix to adjust the weight or improve its durability. The type and amount of these materials will affect the final weight.
Coatings: While not directly contributing to the core weight, coatings like paint or rubberized materials can add a small amount to the overall weight. More importantly, the coating affects the grip, which indirectly impacts the difficulty of the lift.
Typical Weight Ranges of Atlas Stones
Although weights can vary, here are some typical weight ranges you might encounter:
- Novice/Beginner Stones: 100 lbs to 200 lbs (45 kg to 90 kg)
- Intermediate Stones: 200 lbs to 300 lbs (90 kg to 136 kg)
- Advanced/Competition Stones: 300 lbs to 400 lbs+ (136 kg to 181 kg+)
Keep in mind that these are just guidelines. Some competitions may feature even heavier stones, pushing the limits of human strength.
Atlas Stone Dimensions and Their Impact on Weight
Beyond weight, the dimensions of an Atlas stone play a critical role in its liftability. A larger diameter stone, even if not excessively heavy, can be significantly more challenging due to the increased distance the lifter needs to travel to get it into position.
Diameter and Circumference
The diameter of an Atlas stone is the most commonly cited measurement. It directly correlates to the amount of concrete used and, therefore, the weight. Circumference, directly derived from the diameter, also provides insight into the stone’s overall size.
As the diameter increases, the difficulty of the lift increases disproportionately. This is because a larger stone sits further from the lifter’s center of gravity, requiring more strength and stability to control.
Impact of Shape on Stone Weight
While most Atlas stones are spherical, slight variations in shape can occur during the molding process. A perfectly spherical stone will distribute weight evenly, while an imperfectly shaped stone might have slight weight imbalances. Though usually negligible, these small shape variations can contribute to the overall challenge of the lift.
Common Atlas Stone Diameters
Here are some common Atlas stone diameters and their approximate corresponding weights:
- 20-inch (51 cm) Diameter: 100-150 lbs (45-68 kg) – Beginner friendly.
- 22-inch (56 cm) Diameter: 150-200 lbs (68-90 kg) – Suitable for novice lifters.
- 24-inch (61 cm) Diameter: 200-250 lbs (90-113 kg) – Stepping up the challenge.
- 26-inch (66 cm) Diameter: 250-300 lbs (113-136 kg) – Getting into competition territory.
- 28-inch (71 cm) Diameter: 300-350 lbs (136-159 kg) – Serious strongman stone.
- 30-inch (76 cm) Diameter: 350-400 lbs (159-181 kg) – Only for the exceptionally strong.
- 32-inch (81 cm) Diameter and Up: 400 lbs+ (181 kg+) – Elite-level stones.
Remember, these weights are approximations. The actual weight will depend on the concrete mix and other factors.
The Role of Grip and Technique in Lifting Atlas Stones
While the weight of the Atlas stone is a primary factor, grip and technique are equally important for successfully lifting and loading these massive spheres. Without a proper grip and efficient technique, even a relatively lighter stone can prove impossible to lift.
Grip Strength: A Prerequisite for Atlas Stone Lifting
Grip strength is paramount when lifting Atlas stones. The smooth, round surface offers little in the way of purchase, requiring the lifter to rely on a strong, secure grip to maintain control of the stone.
Specialized grip training, such as using grip-strengthening devices and practicing deadlifts with thick bars, is crucial for developing the necessary grip strength. Some lifters also use tacky, a sticky substance applied to the hands and arms, to enhance their grip.
Lifting Technique: Maximizing Efficiency and Minimizing Risk
Proper lifting technique is essential not only for successfully lifting the stone but also for preventing injuries. The Atlas stone lift involves a complex sequence of movements, requiring coordination and control.
The typical Atlas stone lifting technique involves the following steps:
- Positioning: Straddling the stone with feet shoulder-width apart.
- Hugging: Wrapping the arms around the stone, getting as much of the stone into the lap as possible.
- Lifting: Squatting down and driving upwards with the legs and back, pulling the stone off the ground.
- Loading: Continuing the upward motion, using the legs and back to heave the stone onto a platform or over a bar.
Each step requires precise movements and careful attention to form. Rounding the back or relying solely on arm strength can lead to serious injuries.
Tacky: The Strongman’s Secret Weapon
Tacky, a resinous adhesive, is widely used in strongman competitions to improve grip on Atlas stones. It provides a significant advantage, allowing lifters to maintain a secure hold on the stone even when it’s covered in sweat or dirt.
However, the use of tacky is not without controversy. Some argue that it diminishes the importance of raw strength and technique, while others maintain that it is an essential part of the sport. Rules regarding the use of tacky vary from competition to competition.
Training to Lift Atlas Stones
Lifting Atlas stones requires a specific training regimen that focuses on developing both strength and technique. It’s not simply about lifting heavy weights; it’s about building the specific muscles and skills needed to handle these unique objects.
Strength Training for Atlas Stone Lifting
A well-rounded strength training program should include exercises that target the key muscle groups involved in lifting Atlas stones:
- Back: Deadlifts, rows, and pull-ups to build back strength and stability.
- Legs: Squats, lunges, and leg presses to develop lower body power.
- Core: Planks, Russian twists, and dead bugs to improve core stability and control.
- Grip: Grip-strengthening exercises like farmers walks, dead hangs, and using grip-strengthening devices.
Focus on compound exercises that work multiple muscle groups simultaneously. This will help you build the overall strength and power needed to lift Atlas stones.
Technique Practice: Mastering the Art of the Lift
In addition to strength training, it’s essential to practice the specific technique of lifting Atlas stones. Start with lighter stones and gradually increase the weight as your technique improves.
Focus on maintaining proper form and control throughout the lift. Pay attention to your body position, grip, and the way you’re using your legs and back. Consider working with a coach or experienced strongman competitor to get feedback on your technique.
Progressive Overload: Gradual Improvement Over Time
Progressive overload is the key to long-term progress in any strength training program. This means gradually increasing the weight, reps, or sets over time as you get stronger.
When training with Atlas stones, start with a weight that you can comfortably lift with good technique. As you get stronger, gradually increase the weight or the number of reps. Be patient and consistent, and you will see results over time.
Atlas Stones in Strongman Competitions
Atlas stones are a staple in strongman competitions around the world, testing the athletes’ strength, technique, and mental fortitude. The Atlas stone event typically involves lifting a series of stones of increasing weight and loading them onto platforms or over a bar.
The Atlas Stone Event: A Test of Strength and Skill
The Atlas stone event is often one of the most challenging and visually impressive events in strongman competitions. It requires athletes to lift extremely heavy stones and load them onto platforms of varying heights.
The event tests not only the athletes’ raw strength but also their technique, grip, and mental toughness. Athletes must be able to maintain their grip on the stone, even when it’s covered in sweat and dirt, and they must be able to push through the pain and fatigue to complete the lift.
Variations in Atlas Stone Event Format
The format of the Atlas stone event can vary from competition to competition. Some common variations include:
- Loading Stones onto Platforms: Athletes must lift the stones and load them onto platforms of increasing height.

What is the typical weight range for Atlas stones used in Strongman competitions?
The weight of Atlas stones used in Strongman competitions varies significantly based on the level of competition and the specific event requirements. Generally, men’s competitions feature stones ranging from approximately 200 lbs (91 kg) to over 400 lbs (181 kg). The heavier stones are typically reserved for elite-level competitions and final events.
Women’s competitions usually involve lighter stones, typically ranging from around 100 lbs (45 kg) to 250 lbs (113 kg). The exact weight of each stone will be dictated by the organizers of the competition, considering the experience level of the participants and the overall challenge they aim to create. This variance allows for a broader range of athletes to participate and progress within the sport.
How does the size of an Atlas stone influence its perceived weight and difficulty to lift?
While the weight of the stone is the primary factor, the size and shape of an Atlas stone significantly impact its perceived weight and difficulty. A larger diameter stone, even if relatively lighter, can be harder to grip and maneuver due to the increased distance the athlete needs to wrap their arms around it. This requires a stronger grip, core, and back to maintain control.
Additionally, the irregularity in shape that some stones possess (even when cast) can create uneven weight distribution, further complicating the lift. A perfectly spherical and smooth stone might be easier to grip than a slightly oblong one with surface imperfections, even if they weigh the same. Therefore, athletes need to adapt their technique based on both weight and dimensions of each specific stone.
What materials are commonly used to make Atlas stones, and how do these materials affect the stone’s weight?
Atlas stones are most commonly made from concrete due to its affordability, durability, and ease of molding. Concrete allows for creating stones of various sizes and weights relatively inexpensively. The density of the concrete mix, including the type of aggregate used (such as gravel or sand), can influence the final weight of the stone.
In some cases, stones can be made from natural stone, although these are less common due to cost and difficulty in shaping. Natural stones often require specialized equipment for cutting and shaping, and finding stones of the desired weight and size can be challenging. The specific gravity of the material will also determine the weight of the final product, as higher density stone types will result in a heavier finished stone for the same size.
Can I adjust the weight of an Atlas stone I already own, and if so, how?
Adjusting the weight of an existing Atlas stone can be challenging and often involves modifying the stone itself, with limited options available. If the stone is concrete, it’s possible to add weight by embedding metal objects or adding an external layer of concrete, though this requires careful planning and execution to maintain the stone’s integrity and shape. Adding weight is easier than removing it.
Removing weight is more difficult and potentially destructive. You could theoretically chip away at the stone, but this would compromise its structural integrity and create an uneven surface, making it dangerous to lift. Therefore, the best approach is typically to purchase or create a new stone that matches the desired weight, rather than attempting to modify an existing one drastically.
What safety considerations should I keep in mind when lifting Atlas stones, especially heavier ones?
Safety is paramount when lifting Atlas stones, particularly heavier ones. It’s crucial to have proper training and coaching to learn the correct technique, including how to safely wrap your arms around the stone, engage your core, and lift with your legs. Always use a tacky substance on your arms and the stone to improve grip and prevent slippage.
Additionally, ensure you have a clear and safe lifting area, free from obstructions. Use spotters, especially when attempting heavier weights, to assist if you encounter difficulty. Consider wearing appropriate protective gear, such as lifting shoes, a lifting belt, and even shin guards if you are prone to scrapes. Proper warm-up and cool-down routines are also essential to prevent injuries.
What are the key differences between using an Atlas stone and lifting other types of weights, such as barbells or dumbbells?
Lifting Atlas stones is significantly different from lifting traditional weights like barbells or dumbbells due to the stone’s unique shape and instability. Unlike barbells which offer a balanced and stable load, an Atlas stone is a round, often irregularly shaped object that challenges the lifter’s grip strength, core stability, and overall coordination. This makes the lift more of a full-body effort.
The uneven weight distribution and lack of handles also necessitate a different lifting technique. While barbells emphasize symmetrical strength, Atlas stone lifting demands a more adaptable and functional strength. Furthermore, the “loading” component of lifting a stone (i.e. getting it onto the platform or over a bar) introduces an element of athleticism not as prevalent in traditional weightlifting.
How does the surface texture of an Atlas stone affect the grip and overall lift?
The surface texture of an Atlas stone plays a significant role in the grip and overall ease of the lift. A rough or textured surface provides better traction, allowing the athlete to maintain a secure grip, which is crucial when lifting heavy, awkwardly shaped objects. This is why many stones are intentionally cast with a slightly rough finish.
A smooth surface, on the other hand, can be very slippery, especially when combined with sweat or other environmental factors. While some athletes might prefer a smoother stone to reduce friction during the rolling or carrying portion of the lift, a lack of grip can significantly increase the risk of dropping the stone and causing injury. The use of tacky substances is crucial to overcoming a slippery surface.
