Beastmaker Workouts and Training Plans
Most hangboard companies design a product and call it a day. Lattice Training designed an entire training ecosystem, then built the hangboard to match. Founded by crack climbing legend Tom Randall and sports scientist Ollie Torr, Lattice built the world's largest database of climber performance metrics — over 50,000 athletes — and engineered their boards around one question: what does a hangboard need to look like to produce reliable, comparable testing data? This review covers the flagship Triple Rung, the science behind it, and whether the data-driven approach is worth it for your training.

Data-driven climbers who want accurate, comparable finger strength measurements. If you care about knowing exactly where you stand relative to 50,000+ other climbers and tracking progress with real data, the Triple Rung was built for you.
The Brand Behind the Board
Founded in 2015 in Sheffield, UK, by Tom Randall and Ollie Torr, Lattice Training started as a coaching company obsessed with data. Tom Randall is one of the "Wide Boyz," a crack climbing legend with first ascents like Century Crack (5.14b) and The Kraken (V13), plus over 20 years of coaching experience. Ollie Torr is a V13 boulderer, former competitive gymnast, and holds a degree in Sports Science.
Together, they built what has become the world's largest database of climber performance metrics, collected from over 50,000 athletes across every discipline and ability level. The lattice hangboard lineup grew out of that data. Rather than designing a board packed with features and calling it complete, Lattice asked a different question: what does a hangboard need to look like to produce reliable, comparable testing data?
The answer became the Triple Rung, and it changed how the climbing world thinks about fingerboard design. For a full overview of how Lattice fits into the broader market, check out our Hangboard Brand Guide.
The Science Behind Lattice
What makes Lattice different from every other training company is their commitment to research-backed methodology. This is not marketing fluff. Their finger strength testing protocol has been validated in peer-reviewed academic research ("The reliability and validity of a method for the assessment of sport rock climber's isometric finger strength," published on ResearchGate in 2020).
Here is the core insight: most hangboards introduce uncontrolled variables during testing. Sharp edges allow climbers with thick finger pulp to fold their skin over the edge, increasing friction and artificially boosting their scores. Pocketed designs let climbers "nest" their index finger against the side wall, redirecting force to the shoulders instead of measuring true finger flexor strength. These variables make it nearly impossible to compare results between climbers or even between your own sessions.
Lattice solved this by engineering their edges with the largest radius of any board on the market (50% of the edge depth). This large radius prevents skin folding, creating a more controlled testing environment. Combined with a continuous edge (no pockets), the lattice board climbing community now has a standardized tool that produces genuinely comparable data across their entire global dataset.
This matters because your finger strength numbers are only useful if they are accurate. A number that looks good but was inflated by edge geometry does not help you train.
Product Review: The Lattice Triple Rung
The Triple Rung is the flagship lattice hangboard and the board that the entire Lattice dataset is built upon. Released in 2020, it takes a deliberately minimalist approach to edge selection.
The Three Edges
45mm flat edge (top): A generous jug rail that sits about two finger pads deep. Perfect for warming up, pull-ups, scapular stability work, and front levers. This is where every session starts.
20mm edge (bottom): The star of the show. This is the "Lattice benchmark" edge used in every Lattice assessment worldwide. At one finger pad deep, 20mm is the standard training edge for most climbers, and this particular 20mm feels noticeably more comfortable than the same depth on other boards thanks to that generous radius.
10mm edge (middle): A fingertip-depth micro edge for dedicated small-edge strength work. Once you are comfortable on the 20mm, the 10mm gives you a clear progression target.
Three edges might sound sparse compared to boards loaded with pockets, slopers, and jugs. But Lattice makes a compelling argument: you only need a warm-up edge, a training edge, and a progression edge. Want to train pockets? Hang off fewer fingers. The continuous edge design lets you choose your hand width rather than being locked into whatever pocket spacing the manufacturer decided on.
Build Quality and Comfort
The most consistent feedback about the lattice training fingerboard is how comfortable it feels. The large radius edges, combined with the wood construction, make extended sessions far less punishing on skin than resin or polyurethane boards. Wood is naturally less abrasive, so your skin stays in better shape between sessions.
The wider-than-average board (55cm vs. the typical 48cm) is a thoughtful touch. Climbers with broader shoulders can hang at a more natural width, and the extra space allows for wide-grip pull-up variations on the 45mm edge. The single-piece seasoned wood construction feels solid and durable. There are no moving parts, no adjustable components, and nothing to break. It is a beautifully simple piece of training equipment.
The Testing and Assessment System
Buying a lattice hangboard gives you more than a piece of wood. It plugs you into Lattice's entire assessment ecosystem.
My Fingers (Free Assessment)
Every Triple Rung comes with instructions to perform a finger strength self-assessment. But you can also use Lattice's free "My Fingers" tool online. Test your max hang on a 20mm edge, input your data, and Lattice compares your results against their global dataset of climbers. You will get a report showing whether your lattice finger strength scores are strong, average, or weak relative to other climbers at your grade.
This is genuinely powerful. Instead of guessing whether you need more finger strength or should focus on technique, endurance, or power, you get an objective answer backed by the largest climbing dataset in existence. Test as often as you want to track progress over time.
Paid Assessments and Coaching
Beyond the free tool, Lattice offers comprehensive paid assessments covering multiple performance metrics and personalized coaching plans delivered through their app. Their coaching has supported over 50,000 climbers, from total beginners to professional athletes. The lattice training hangboard is designed to integrate directly with these plans, since every protocol references the same 20mm benchmark edge.
How to Integrate the Triple Rung into Training
The Triple Rung works with any standard hangboard training protocol. Here are two proven approaches:
Max Hangs (Eva Lopez Progressive Loading)
The 20mm edge is perfect for max hang protocols. Load up with added weight (or remove weight with a pulley) and perform 3 to 5 sets of 7 to 10 second hangs at high intensity, with 3 to 5 minutes rest between sets. Progress by adding weight or moving to the 10mm edge. Research by Eva Lopez showed strength gains up to 28% over 8 weeks using this approach.
Repeaters (Anderson Brothers Protocol)
Use the 20mm or 10mm edge for 7 seconds on, 3 seconds off, repeated for 6 cycles per set. This targets strength endurance and is excellent for building the sustained grip you need on longer routes and boulder problems.
The beauty of the Triple Rung's simplicity is that it removes decision paralysis. You are not choosing between twelve different holds. You pick an edge, pick a protocol, and train. For more protocol breakdowns and board comparisons, check our guide to the best hangboards.
Strengths
Data-Backed Design
No other hangboard can claim peer-reviewed validation of its testing accuracy. The lattice hangboard was engineered for reliable measurement first and training second, which means you always know exactly where you stand.
Edge Comfort
The large radius and wood construction make the Triple Rung one of the most comfortable boards on the market. Sessions feel better, skin lasts longer.
Ecosystem Integration
The free My Fingers assessment, paid coaching plans, and the Lattice app create a complete training loop. The board is not just a tool; it is the entry point to an entire system.
Wider Build
At 55cm, climbers of all frames can find a comfortable hanging position without feeling crowded on the board.
Simplicity
Three edges. No gimmicks. This board does exactly what it needs to do and nothing more.
Limitations
Minimalist Edge Selection
If you want slopers, pinches, or multiple pocket widths on a single board, the Triple Rung does not have them. The philosophy is intentional, but climbers who want more variety will need a second board or supplementary tools.
No Mounting Hardware
You will need to source your own wood screws (6 required). Standard for many boards but worth noting for first-time buyers.
UK-Based Pricing
Shipping outside the UK and EU can add cost. US retailers like PhysiVantage and Training for Climbing now stock it domestically, which helps.
Testing Specificity
The full value of the lattice hangboard emerges when you use it with the Lattice assessment system. If you are not interested in testing and just want a general training board, you are paying for features you will not use.

vs. The Hangboard
The Hangboard offers six labeled standard-depth edges in a clean, single-piece beech wood design for $89.99. If you want simplicity with standard edge sizes that match any published protocol, The Hangboard is the cleaner and more affordable fit. The Lattice wins if data-driven testing and global comparison matter to you — but for pure training utility, both boards get the job done.
vs. Beastmaker 2000
The Beastmaker 2000 offers far more hold variety: pockets, slopers, and edges in a beautiful tulipwood build. It is the more versatile board for general training. The Lattice Triple Rung counters with scientific rigor — validated testing, a global dataset, and the most comfortable edges in the game. Many serious climbers own both.
vs. Tension Grindstone
The Tension Grindstone is a dedicated edge-training board with labeled depths from 30mm to 8mm — more edge options than the Triple Rung. It is widely considered one of the most comfortable hangboards available. The Lattice distinguishes itself through the assessment ecosystem: free testing, coaching integration, and the global database. For pure edge variety, the Grindstone wins.

Labeled beech wood edges from 40mm to 10mm at $89.99
If you want standard-sized labeled edges that match any published training protocol, The Hangboard delivers beech wood, six depths from 40mm down to 10mm, and simple single-piece mounting for $89.99. All the training utility without the premium price — simplicity and structure at a competitive price.
The Verdict
The Lattice Triple Rung is not trying to be the most versatile hangboard on the market. It is trying to be the most accurate and reliable, and it succeeds. The combination of peer-reviewed edge design, the world's largest climber dataset, free finger strength assessments, and integration with professional coaching plans makes this lattice climbing board something genuinely unique.
If you want to know exactly how strong your fingers are, track your progress with real data, and train on the same standardized edge used by over 50,000 climbers worldwide, the Triple Rung is the board. The science is real, the comfort is excellent, and the ecosystem around it turns a simple piece of wood into a complete training platform.
If you want more hold variety or a lower price point, boards like The Hangboard, the Beastmaker 2000, and the Tension Grindstone all offer strong alternatives. But for the data-obsessed climber, nothing else comes close to what Lattice has built.

The Lattice Triple Rung features three edges: a 45mm flat edge for warming up and pull-ups, a 20mm "benchmark" edge used for standardized finger strength testing, and a 10mm edge for small-edge strength training. All three edges use a large radius design for comfort and consistent testing.
Yes. The 45mm edge is comfortable for anyone to start on, and the continuous edge design lets you choose your own hand width. Beginners can use feet-on-the-ground modifications to reduce load, then progress to full bodyweight hangs and eventually add weight. The free My Fingers assessment also helps beginners establish a baseline right away.
Perform a max hang on the 20mm edge (with or without added weight) and input your results into Lattice's free My Fingers tool. Lattice compares your data against their global dataset of climbers and generates a report showing how your finger strength compares to others at your climbing grade. You can retest as often as you like to track progress.
Absolutely. The Triple Rung works with max hangs, repeaters, density hangs, or any other standard hangboard protocol. The 20mm edge is the ideal depth for max hang work, while the 10mm provides progression for advanced training. The 45mm edge handles warm-ups and general upper body exercises.
Pockets introduce variability in testing because climbers can "nest" their fingers against the side walls, increasing friction and making results less accurate. The continuous edge design lets each climber choose their optimal hand width and ensures that finger strength scores reflect true flexor strength rather than edge geometry advantages.
At roughly $170-200 USD, the Triple Rung is a premium investment for a minimalist wooden hangboard. The real value comes from the ecosystem: free finger strength assessment, access to the world's largest climber dataset, and seamless integration with Lattice coaching plans and the Lattice app. If data-driven training matters to you, it delivers outsized value for the price.
