CONTEXT

Elevating Performance Through Structured Practice

Elevating Performance Through
Structured Practice

Brazilian Jiu-Jitsu rewards precision: progressing from beginner to mastery hinges on a deep understanding of technique and deliberate, focused practice. Yet, as the sport grows, practitioners face increasing complexity, with countless techniques to learn, refine, and integrate. Maximising improvement isn’t just about more hours on the mat; it’s about smarter, more targeted training.

THE CHALLENGE

Unlocking Accelerated, Sustainable Growth for Serious Athletes

Unlocking Accelerated, Sustainable Growth
for Serious Athletes

Most dedicated Jiu-Jitsu athletes want to advance quickly, but simply increasing training intensity isn’t feasible(or safe). Too much physical strain risks injury, while unfocused repetition leads to plateaus.

The real opportunity is to transform passive training into intentional, data-driven practice. This empowers athletes to set clear goals, receive actionable feedback, and track progress in ways previously limited to private coaching.

For a solution to deliver real value:

It must be intuitive and adaptable to varying experience levels.

It should break complex sequences into approachable actions without overwhelming users.

It must seamlessly integrate into existing training routines to drive sustained engagement.

UNDERSTANDING THE PROBLEM

Barriers Holding Back Progress

Many motivated but less experienced Jiu-Jitsu athletes lack efficient tools and feedback systems to accelerate skill development. With overwhelming technique variety, unstructured learning, and a lack of integrated tracking, they struggle to structure their practice and pinpoint weaknesses—leading to slower progress.

Jiu-Jitsu athletes lack efficient tools and feedback systems to accelerate skill development. With overwhelming technique variety, unstructured learning, and a lack of integrated tracking, they struggle to structure their practice and pinpoint weaknesses—leading to slower progress.

Overwhelming Skill Organization – Athletes lack efficient, organised systems to manage and review the overwhelming variety of techniques.

Difficulty Pinpointing Weaknesses – Athletes find it challenging to identify and address their weaknesses due to limited personalised coaching and delayed feedback, making it difficult to track and correct recurring small mistakes that impact overall progress.

Fragmented Practice & Tracking Tools– Current note-taking or tracking solutions are generic and unsuited to the dynamic, visual demands of Jiu-Jitsu, leaving athletes without an effective way to bridge learning, practice, and reflection.

CHALLENGE

How might we help beginner Jiu-Jitsu athletes shift from passive repetition to intentional practice, so they can overcome early learning challenges, retain skills, and gain the confidence to advance?

INTRODUCING

Interactive Technique Mind-Mapping

A dynamic visual mind map to help athletes intuitively organise, connect, and revisit an ever-expanding library of Jiu-Jitsu techniques. By attaching personal insights and timestamped video clips to each technique node, learners create a custom knowledge base that mirrors how experts categorise and recall technical details.

Dynamic visualisation– Athletes map techniques as nodes, clarifying relationships and facilitating efficient review.

Colour-coded
nodes

To enhance the visual hierarchy and improve cognitive recognition, we applied distinct colours to differentiate between node types within the technique map.

Positions= Blue : Stability and control, the foundations of BJJ
Transitions= Green : Movement, progress between positions

Submissions = Orange : Energy, High-stakes action of submissions

INTRODUCING

Error Tracking

An integrated micro-tracking system lets athletes log and categorize mistakes with a simple “fail counter” for specific technique details. After training, users can quickly record missed grips, timing errors, or other issues, which the system then visualises as patterns and trends over time.

Athletes gain tailored feedback loops, previously accessible only through one-on-one coaching, that directly inform their next practice focus. This drives measurable progress and user satisfaction, while providing the business with data for future personalised coaching features.

Focused Micro-Error
Tracking

Focused Micro-Error Tracking

Each technique includes a straightforward voting-style control, serving as a “fail counter” to log specific errors during training. Users can filter technique details by recency or frequency of mistakes, and quickly rearrange priorities using a drag-and-drop interface.

INTRODUCING

Effortless Cross-Device Access

Recognising the need for on-the-fly learning, we prioritised a responsive, cloud-synced platform that fits naturally into diverse training scenarios- at home, in the gym, or anywhere.

This ensures knowledge is always accessible, significantly increasing adoption and daily active usage, making Roll Recall an indispensable tool in athletes’ progression.

Universal access ensures users have seamless transitions between desktop (deep analysis) and mobile (instant review) experiences.

Real-time sync supports continuity and consistency, reducing the friction of switching contexts.
