Took it to my gym once… now people ask if they can borrow it. Spoiler: they can’t.

Super light, super easy to move. I take it out to the backyard and inflate in under a minute. Game changer.

Switched from a wooden plyo box to this and instantly felt the difference. Way less impact.

I’m a personal trainer and it fits in my trunk. Clients love it. Looks cool too.
