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. 3D motion tracking technology claims to gather information about your form and technique and provide insights.
