Qmulus Cube is loved by thousands
I needed something quiet, compact, and easy to throw into my chaotic day. This thing is shockingly effective—I work up a sweat in minutes, and it doesn’t shake the whole apartment like my jump rope used to. Love that I can stash it under the bed, too.
I train clients recovering from knee injuries, and I’ve tested just about every “low-impact” product out there. The Qmulus Cube is one of the few that actually delivers. It absorbs shock beautifully—no jarring on the knees or ankles. And bonus: it’s actually fun. Clients feel safe and challenged, which is rare.
I sit all day. My back and hips were getting stiff, and traditional cardio was just too much impact. Qmulus lets me move, stretch, and sweat without pain. Feels like I’m jumping on something soft, but it fires up my whole body. I’m low-key obsessed.
Honestly, I was skeptical. A cube? Really? But it’s not just any cube—it’s like a bounce pad that tones your legs and glutes like crazy. The material feels premium, and it doesn’t slide around. I use it barefoot and it feels so natural.
My joints were done with burpees. Qmulus gave me a way back into high-intensity workouts without the punishment. It’s weirdly satisfying to jump onto, and it keeps me moving without flaring up my knees.
I’ve had two ankle surgeries. Wasn’t sure I’d ever jump again. This cube gave me a safe way to rebuild confidence and mobility. It’s soft but stable, and doesn’t wobble under pressure. Worth every penny.
I needed something that wasn’t noisy, didn’t take up space, and didn’t need Wi-Fi to work. Found it. The Qmulus Cube lives behind my couch and gets pulled out every evening for quick bursts of cardio. And yeah, it looks cool too.
I use the Cube with my students for agility and jump drills. It teaches proper landing mechanics and keeps injuries down. Plus, they think it’s “cooler than cones,” so that’s a win in my book.

I can finally workout while the baby naps—no loud machines, no heavy thumping. It’s like a portable fitness mat that helps me sweat safely. And it’s kinda cute? Which matters when it lives in your living room.
We use this during downtime at the station. Great for lateral hops, single-leg work, and mobility drills. The impact absorption is next level—it protects our knees without compromising intensity.
I’m on my feet 12 hours a day. My calves and knees used to ache. Started using the Cube for quick 10-min routines before work and I swear it’s made a difference. It’s like a mini rebounder but way more stable.
I love incorporating it into warm-ups and active recovery sessions. Clients find it approachable, even if they’re intimidated by traditional fitness gear. Plus it’s easy to clean—essential for studio life.
Working from home wrecked my energy. I use the Cube for short cardio bursts between meetings. It’s quick, joint-safe, and surprisingly motivating. 15 minutes feels like a full-on session.
Back pain used to stop me from working out consistently. This thing absorbs enough impact that I don’t get that post-workout soreness anymore. And it’s helping me stay consistent, which is half the battle.
It’s a beautiful balance tool. My clients use it for grounding, jumping, and even seated stretches. The texture’s just right—not slippery or too soft. It’s earned a permanent place in my studio.
Can’t afford a gym. Don’t need one. This little cube is way more brutal than it looks. Jump squats, lateral bounds, knee tucks—it turns my dorm room into a conditioning circuit.
I wasn’t trying to get “ripped”—I just wanted to move more without pain. The Qmulus Cube makes me feel strong without punishment. I actually look forward to using it, which is saying something.

Back pain used to stop me from working out consistently. This thing absorbs enough impact that I don’t get that post-workout soreness anymore. And it’s helping me stay consistent, which is half the battle.
It’s a beautiful balance tool. My clients use it for grounding, jumping, and even seated stretches. The texture’s just right—not slippery or too soft. It’s earned a permanent place in my studio.
Can’t afford a gym. Don’t need one. This little cube is way more brutal than it looks. Jump squats, lateral bounds, knee tucks—it turns my dorm room into a conditioning circuit.
I wasn’t trying to get “ripped”—I just wanted to move more without pain. The Qmulus Cube makes me feel strong without punishment. I actually look forward to using it, which is saying something.
I can finally workout while the baby naps—no loud machines, no heavy thumping. It’s like a portable fitness mat that helps me sweat safely. And it’s kinda cute? Which matters when it lives in your living room.
We use this during downtime at the station. Great for lateral hops, single-leg work, and mobility drills. The impact absorption is next level—it protects our knees without compromising intensity.
I’m on my feet 12 hours a day. My calves and knees used to ache. Started using the Cube for quick 10-min routines before work and I swear it’s made a difference. It’s like a mini rebounder but way more stable.
I love incorporating it into warm-ups and active recovery sessions. Clients find it approachable, even if they’re intimidated by traditional fitness gear. Plus it’s easy to clean—essential for studio life.
Working from home wrecked my energy. I use the Cube for short cardio bursts between meetings. It’s quick, joint-safe, and surprisingly motivating. 15 minutes feels like a full-on session.

Whether you’re on your living room floor or squeezing in a session between Zoom calls, it fits right into your life (and your space).
Our mission? Simple. Help real people move better, feel better, and actually enjoy working out—without needing a full gym or punishing routine.
