GROWL combines advanced hardware, software and content to create an interactive, personalized boxing and fitness experience at home.
Here’s how each component works together:
- Immersive Projection: A life-sized virtual coach is projected onto the bag, guiding you through each workout as if they’re right there beside you, combined with additional information such as score and statistics projected on the sides of the wall.
- Interactive Sensing: Multi-directional time-of-flight sensors, located above the punching bag, capture every punch with pinpoint precision—measuring power, speed, and accuracy—and transform the bag into a responsive, touch-sensitive surface.
- AI-Powered 3D Motion Tracking: Our on-device, multi-camera 3D motion tracking continuously monitors your form and provides real-time, personalized insights to sharpen your form and technique with every round.
- Advanced Gaming Power: GROWL harnesses the power of a dedicated Nvidia GPU and Unreal Engine 5 to create immersive, gamified environments that react dynamically to your actions, making every workout feel like an exciting, interactive challenge.
- Revolutionary Boxing Bag: Our boxing bag is unlike any other, designed with a multi-layer composite architecture to provide the perfect balance of resistance—accessible for beginners yet challenging for advanced boxers.
- Dynamic Lighting & Sound: Integrated LEDs and premium speakers sync music, lighting, and effects with your punches, bringing the energy and atmosphere of a high-energy fitness studio into your home.
Yes, GROWL works in both darkness and normal indoor lighting conditions, delivering crisp and immersive visuals.
However, very bright or direct sunlight reflecting on the bag may reduce projection clarity and vibrancy, which can impact the overall experience.
For the best results, we recommend placing GROWL in a spot where you can dim the lights or close the blinds–similar to how you’d prefer a dimmed environment when watching a TV screen for optimal picture quality.
Yes. GROWL’s “workout together” circuit mode turns your home into a mini fitness studio for two.
One person takes on the bag while the other tackles exercises projected onto the wall. Then you switch stations—just like a tag-team, crossfit-style challenge that keeps both of you moving, motivated, and having a blast.
It’s a perfect way for friends or family members to bond, sweat, and smash their fitness goals together!
GROWL is recommended for ages 10 and up (with a recommended height of at least 4’8″), making it a great option for families to stay active together.
GROWL is designed to adapt to a variety of home environments, including guest rooms, fitness spaces, garages, and basements.
Installation Requirements:
- Ceiling Height: A minimum of 7’9” is required for proper installation.
Recommended for the Best Workout Experience:
- Floor Space: 10′ x 10′ to allow full freedom of movement during workouts.
- Unobstructed Wall Space: 10′ to accommodate GROWL’s interactive projection and features.
That said, GROWL is adaptable–you can still enjoy effective workouts in slightly smaller areas by modifying certain of your movements if your space is smaller.
We provide professional white-glove delivery and installation to ensure a flawless setup.
Before installation, our support team will work with you to select the ideal location for GROWL in your home. Once confirmed, a two-person team will deliver your GROWL, expertly mount it to your wall, connect it to WiFi, and ensure everything is running perfectly.
The process is quick, clean, and hassle-free—similar to mounting a flat-screen TV—leaving your walls pristine and your GROWL ready for action.
