If you’ve ever been to a boxing workout in a studio, we’re sure you’re as skeptical as we are about how well you can translate that experience of intense sweat, movement and grind into a digital workout, especially if most of us don’t have a bag at home. Somehow Box Union has managed to do exactly that. This Los Angeles based boxing studio provides both live and VOD boxing workouts that leave you with that same absolutely-dead-tired can’t believe I worked out that hard feeling that you get from finishing a class in one of their studios.

Each class is a combination of traditional boxing moves, cardio and high intensity interval training, performing each move to the rhythm of a song. These total body workouts are extremely effective, and even if you’re doing the entire workout with no gloves and no weights, you’ll wake up the next day and wonder where all those muscles in your side body came from. And then you’ll immediately find yourself loading another class, ready to do it all over again.

Yeah, it’s really that good.
