GROWL offers a variety of workouts, including fitness boxing, technical boxing, gamified sessions, strength and conditioning, yoga, and flexibility routines. GROWL uses advanced projection technology to display a life-size coach directly on the bag. The AI-powered 3D motion tracking captures your movements in real time, offering personalized feedback to help you improve.
No prior boxing experience is required. GROWL is built to welcome everyone, from first-timers to seasoned pros.
You’ll find step-by-step tutorials, progressive training programs, and real-time coaching that help beginners learn proper technique while pushing advanced users to new heights.
Definitely. GROWL’s punching bag has been rigorously tested by users of all shapes, sizes, and skill levels—including professional boxers, MMA fighters, and even a former UFC Heavyweight Champion. Its multi-layered, durable construction can take your hardest punches without breaking a sweat, ensuring you can unleash your full power with total confidence.
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.
Absolutely. Your GROWL membership includes unlimited user profiles, making it an ideal choice for families and households of all sizes.
Everyone aged 10 and up can create their own profile, access personalized workouts, and track individual progress. Whether it’s parents, teens, or siblings, each user enjoys customized coaching, goals, and content—ensuring that GROWL fits everyone’s fitness journey under one roof.
GROWL is designed to adapt to a variety of home environments, including guest rooms, fitness spaces, garages, and basements.
Recommended ceiling height for best workout experience: A minimum of 7’9” is required for proper installation.
Recommended floor space for best workout experience: 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.
