In the geometry of climbing, the circle is often overlooked. We train on linear edges, rectangular blocks, and angular planes. Yet true finger mastery demands conversation with every dimension. Imagine a training tool that curves to meet your grip, that holds the entire spectrum of pocket depth within its circumference, that travels with the simplicity of a carabiner and challenges with the complexity of a moon hang board. Stop imagining.
Introducing the Two Stones Modular Pocket Training Rings—where circular design meets linear progression, where warmth of wood meets cold precision of engineering, and where your pocket strength weaknesses finally meet their match.
Chapter 1: The Geometry of Mastery — Multi-Functional Design
This is not a hangboard. This is a pocket university suspended from a carabiner.
The Pull-Up Ring Reimagined
At first glance, it appears as a pair of elegant wooden rings—perfect for pull-ups, rows, and functional upper-body training. But look closer. Embedded within each ring's circumference is a graduated progression of five distinct 4-finger pocket depths. From the generous comfort of a deep pocket to the skin-tight demand of a shallow edge, the entire spectrum lives here.
The Specialist's Arsenal
But why stop at four fingers? Carved strategically into the design are dedicated 2-finger pockets and—for those seeking the ultimate test of connective tissue integrity and mental fortitude—a singular 1-finger pocket. This isn't random variety; it's a calculated training ecosystem. Warm up on the deep four-finger pockets, build capacity on the two-finger slots, and test your limits on the monos. All without changing equipment, all within the natural rotation of a circular tool that encourages proper shoulder and wrist alignment.
Chapter 2: The Warmth of Wood — Skin-Friendly Natural Material
In an era of cold polymers and sharp alloys, we return to what fingers know best: wood.
Nature's Perfect Texture
Each ring is crafted from solid hardwood, selected for its ideal combination of density and grain. The natural surface provides positive friction without abrasion—that magical balance where chalk sticks perfectly but skin doesn't tear. Unlike plastic that becomes slick with sweat or metal that numbs in cold weather, wood maintains consistent, communicative friction across conditions.
Milled to Perfection
Through precision CNC milling, the wood is shaped without compromise. There are no burrs, no sharp edges, no manufacturing artifacts—just clean curves that welcome your fingers. The material itself has a slight give, a microscopic forgiveness that plastic lacks, making prolonged sessions not just possible but productive.
Chapter 3: Minimalist Logistics — The Perfect Traveling Partner
True training consistency happens when your tools match your lifestyle.
The Numbers That Matter
- Radius: 190mm (7.48 inches)—large enough for comfortable pull-ups, small enough for precise pocket work
- Weight: 580g per pair—lighter than most climbing shoes, comparable to a water bottle
- Pack Factor: Stows in any backpack compartment, slips into luggage unnoticed
The Travel-Ready Mindset
These aren't garage-bound implements. They're designed for global mobility. Warm up at the crag before your project. Maintain finger strength during business trips. Transform a hotel doorway, a park playground, or a hostel bunk bed into an instant training station. When training integrates seamlessly into life, plateaus become mere stepping stones.
Chapter 4: Integrity by Design — The Complete Wood Block Philosophy
Strength training requires trust. You cannot commit to hanging from uncertainty.
Unibody Construction
Each ring begins as a single, solid wood block. Through CNC precision milling, the pockets and curves emerge from the whole—no gluing, no laminating, no weak points. The grain flows continuously around each pocket, following the natural strength lines of the material. This is integrity you can feel: when you load a one-finger pocket, the entire ring shares the stress, not just a glued-on component.
The Durability Promise
Solid wood, properly maintained, outlasts generations of training. Unlike plastic that degrades with UV exposure or composites that delaminate with moisture cycling, these rings grow more familiar with time. The wood may darken slightly with chalk and sweat, developing the patina of dedicated use—a visual diary of your progress.
Chapter 5: Universal Language — For Beginners and Advanced Climbers
The most elegant designs speak to everyone in their own language.
For Beginners: The Gateway
Start with pull-ups. The rings' diameter and wooden texture make themmore forgiving than metal bars, reducing joint stress while building foundational strength. Use the deepest pockets for assisted hangs. The circular form naturally encourages proper scapular engagement and grip variety.
For Advanced Climbers: The Laboratory
The shallow pockets demand more than strength—they require precision, body tension, and neurological efficiency. The one-finger pocket becomes a diagnostic tool for connective tissue health and recruitment capability. The variety within a single tool allows for complex workouts: pull-ups on the outer curve, offset training using different pocket depths on each hand, or one-arm progressions with perfect grip options.
Chapter 6: The Details That Matter — Trusted Quality
Excellence lives in execution, not just concept.
The R5 Fillet
Every pocket edge receives the signature R5 fillet treatment—a precisely calculated radius that eliminates hot spots without sacrificing engagement. This isn't merely "sanded smooth"; it's engineered ergonomics. Your fingers meet the wood not at a sharp intersection, but along a gradual transition that distributes pressure optimally.
Triple-Stage Polishing
After milling and filing, each surface undergoes progressive polishing: coarse shaping, fine sanding, and final buffing with fabric discs. The result is a surface that feels simultaneously secure and silken—friction where you need it, smoothness where you don't. The pockets' interior walls receive particular attention, ensuring consistent texture from entry to back wall.
Epilogue: Closing the Circle
The Two Stones Modular Pocket Training Rings climbing training board represent more than clever engineering. They represent a philosophy: that strength should be accessible, that progression should be incremental, and that the best tools disappear into the practice, leaving only the conversation between athlete and obstacle.
They ask a simple question: What if your greatest weakness became your most trained attribute?
The answer lies not in more equipment, but in better design. Not in complicated protocols, but in consistent engagement. Not in waiting for perfect conditions, but in creating them wherever you are.
