Bhout’s AI-Powered Punching Bag: How Portugal’s Startup Ecosystem is Shaping the Future of Fitness

In the latest episode of our Tech Odyssey series, we ventured beyond the corridors of Startup Portugal to explore one of the innovative startups emerging from the country’s tightly connected innovation ecosystem. This time, we discovered Bhout, a company that’s revolutionizing fitness training with what they claim is the world’s first AI-powered punching bag.

At first glance, the punching bag inside Bhout’s Lisbon gym looks ordinary. But once you throw a punch, the difference becomes clear. The bag barely swings, and the impact feels surprisingly close to striking a human body. A nearby screen instantly displays the data behind each strike—power, speed, location, and movement accuracy.

From Martial Arts Dream to Technological Innovation

Bhout describes their device as the world’s first AI-powered punching bag. According to founder Mauro Frota, the idea started with a dream 11 years ago—though Mauro is not an engineer. His background is in martial arts and the fitness industry, where he spent years observing the same challenge: retention. Getting people to join a gym is easy; getting them to keep coming back is much harder. Training often feels repetitive, and progress is difficult to measure. The concept behind Bhout was simple—turn training into something interactive.

The first prototypes were built in a garage. Over six years, Mauro and his co-founder developed a layered punching bag designed to mimic the resistance of the human body. Sensors embedded throughout the bag work with a 3D computer vision system to track each strike, measuring force, speed, accuracy, and fatigue in real time.

Transforming Data into Motivation

The data transforms training into a game-like experience. Users earn points for every strike and compare scores on gym leaderboards. The system also adapts workouts based on a person’s height, fitness level, and training goals, making it usable for beginners, children, and professional fighters alike.

Beyond gym settings, the technology has also been adopted for neurorehabilitation in Parkinson’s patients and hand-to-hand combat training for military personnel. This versatility demonstrates how fitness technology can transcend traditional boundaries and serve diverse needs.

Scaling the Model Globally

Four years ago, Bhout opened its first gym in Lisbon. According to the company, it has since become the most profitable boxing gym in Portugal. The model is designed to scale: there is no traditional front desk, and most operations—from booking to class management—are handled by software.

As of the end of 2025, Bhout has secured partnerships with more than 500 gyms worldwide, expanding from Portugal and Spain to the United States and Mexico. China is next. Mauro says the company plans to open its first location in Beijing in 2026.

Like many Portuguese startups, Bhout has had to think globally from the beginning. The domestic market is small, and growth depends on international expansion. Portugal’s startup ecosystem, nurtured by initiatives like Startup Portugal, has created an environment where companies can develop world-class innovations and compete on the global stage.

The Future of Fitness is Interactive

What makes Bhout particularly fascinating is how it addresses a fundamental problem in fitness: motivation. By gamifying the training experience and providing immediate, measurable feedback, the company has created a system that keeps users engaged. The leaderboard feature taps into our competitive nature, while the adaptive workouts ensure that everyone from beginners to professionals can benefit.

The company’s success also highlights the potential of combining traditional disciplines like martial arts with cutting-edge technology. By respecting the fundamentals of combat sports while enhancing them with AI and sensors, Bhout has created something that appeals to both purists and tech enthusiasts.

Portugal’s Growing Tech Reputation

Bhout’s journey from a garage prototype to international expansion is emblematic of Portugal’s growing reputation as a tech hub. The country has invested heavily in creating an ecosystem that supports startups, from government initiatives to private investment. Companies like Bhout demonstrate that Portugal can produce not just software startups but also hardware innovations that require significant R&D and manufacturing expertise.

As we continue our Tech Odyssey through Portugal’s innovation landscape, Bhout stands as a testament to how a simple observation about a common problem—gym retention—can lead to a groundbreaking solution when combined with the right technology and entrepreneurial spirit.

The story of Bhout is still being written, but with plans for global expansion and continuous technological refinement, this Portuguese startup is punching well above its weight class in the competitive world of fitness technology.
