Lattice Hangboard Review: Science-Based Training Board
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 Tom Randall and Ollie Torr in Sheffield, UK, Lattice has the world's largest database of climber performance metrics — over 50,000 athletes — and a peer-reviewed testing protocol that no other board can claim.
The Brand Behind the Board
Lattice Training was founded in 2015 in Sheffield, UK, by Tom Randall and Ollie Torr. 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 directly out of that data. 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. 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 skin over the edge, artificially boosting scores. Pocketed designs let climbers "nest" their index finger against the side wall, redirecting force to shoulders instead of measuring true finger flexor strength.
Lattice solved this by engineering edges with the largest radius of any board on the market (50% of the edge depth). This large radius prevents skin folding, creating a controlled testing environment. Combined with a continuous edge (no pockets), the Lattice board produces genuinely comparable data across their entire global dataset.
This matters because your finger strength numbers are only useful if they're accurate.
Lattice Triple Rung
Peer-reviewed edge design with the world's largest climber dataset
The Three Edges
45mm flat edge (top): A generous jug rail, about two finger pads deep. Perfect for warming up, pull-ups, scapular stability work, and front levers.
20mm edge (bottom): The star of the show. This is the "Lattice benchmark" edge used in every Lattice assessment worldwide. The generous radius makes it noticeably more comfortable than the same depth on other boards.
10mm edge (middle): A fingertip-depth micro edge for dedicated small-edge strength work. Clear progression target once you're comfortable on the 20mm.
Three edges might sound sparse. But Lattice makes a compelling argument: you only need a warm-up edge, a training edge, and a progression edge. Want pockets? Hang off fewer fingers. The continuous edge design lets you choose your hand width rather than being locked into the manufacturer's pocket spacing.
Build Quality and Comfort
The most consistent feedback is how comfortable the Triple Rung feels. Large radius edges combined with wood construction make extended sessions far less punishing on skin. The wider-than-average build (55cm vs typical 48cm) lets climbers of all frames find a comfortable hanging position.

- Full value requires using the Lattice assessment system
Data-driven climbers who want accurate finger strength measurement, structured training, and access to the world's largest climber dataset for comparison. If you care about knowing exactly where you stand, this is the board.
The Testing and Assessment System
My Fingers (Free Assessment)
Test your max hang on a 20mm edge, input your data, and Lattice compares your results against their global dataset of 50,000+ climbers. You get a report showing whether your finger strength scores are strong, average, or weak relative to other climbers at your grade. Test as often as you want to track progress over time.
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.
Paid Assessments and Coaching
Beyond the free tool, Lattice offers comprehensive paid assessments and personalized coaching plans delivered through their app. Their coaching has supported over 50,000 climbers, from total beginners to professional athletes.
How to Integrate the Triple Rung into Training
The Triple Rung works with any standard hangboard training protocol:
| Protocol | Edge | Structure | Best For |
|---|---|---|---|
| Max Hangs | 20mm | 3–5 × 7–10s, 3–5 min rest | Peak finger strength |
| Repeaters | 20mm or 10mm | 7s on / 3s off × 6 cycles | Strength endurance |
| Abrahangs | 20mm | Sub-max, 2×/day | Tendon adaptation |
The beauty of the Triple Rung's simplicity is that it removes decision paralysis. You pick an edge, pick a protocol, and train. Eva Lopez's research showed strength gains up to 28% over 8 weeks using max hangs on a 20mm edge.
How It Compares
The Triple Rung occupies a unique space. Most boards compete on how many hold types they can cram onto one piece of material. The Lattice approach is the opposite: do fewer things, but do them better than anyone else.
| Board | Price | Edges | Labeled | Assessment | Best For |
|---|---|---|---|---|---|
| Lattice Triple Rung | $170–200 | 45, 20, 10mm | Yes | Free + paid | Testing & data-driven training |
| Tension Grindstone Mk2 | $170.90 | 8–30mm | Yes | No | Premium edge progression |
| The Hangboard | $89.99 | 10–40mm | Yes | No | Best value edge range |
| Beastmaker 2000 | ~$149 | ~15–33mm | No | App | Advanced hold variety |
If your priority is accurate finger strength measurement and structured, data-driven training, no alternative matches this ecosystem. If you want a board with slopers, jugs, and varied pocket sizes for general training variety, a multi-hold board like The Hangboard or the Beastmaker 2000 is a better fit.
Many serious climbers own both: a feature-rich board for variety and a Lattice board for testing and benchmark training.

The Verdict
The Lattice Triple Rung is not trying to be the most versatile hangboard on the market. It's 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 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 turns a simple piece of wood into a complete training platform.
The most scientifically validated hangboard available. Best for climbers who prioritize accurate testing, data comparison, and structured progression. Pair with a multi-edge board for maximum training coverage.

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 use a large radius design for comfort and consistent testing.
Yes. The 45mm edge is comfortable for anyone. Beginners can use feet-on-ground modifications and progress to full bodyweight hangs. The free My Fingers assessment helps establish a baseline right away. See our beginner's guide for more.
Perform a max hang on the 20mm edge (with or without added weight), input your results into Lattice's free My Fingers tool, and Lattice compares your data against their global dataset of 50,000+ climbers. You can retest as often as you like.
Pockets introduce variability because climbers can "nest" fingers against side walls, increasing friction and making results less accurate. The continuous edge design ensures finger strength scores reflect true flexor strength rather than edge geometry advantages.
At $170–200, it's a premium investment for a minimalist board. The real value is the ecosystem: free finger strength assessment, access to the world's largest climber dataset, and integration with Lattice coaching plans. If data-driven training matters to you, it delivers outsized value.
