This new startup wants to be your AI-powered boxing coach

The connected fitness boom of pandemic-era lockdowns is long behind us (hopefully), but Growl, a new startup, is still looking to bolt a workout to the wall of your home. Think of Tonal, except instead of resistance training, it's a boxing-inspired heavy bag session. The wall-mounted Growl is, according to the company, powered by AI and Unreal Engine and appears to have overhead projectors, which beam the image of a life-sized coach onto the convex punching surface. Besides the projection, the bag has an interactive coaching system to help motivate users. It also supposedly supports side-by-side training, which works great for training partners.
