You’re staring at this tiny black box in the corner of the gym or on a late-night infomercial and thinking, "There is no way that replaces a rack of dumbbells." It looks like a footstool. Honestly, the first time I saw the Fitt Cube HIIT machine 2 cords setup, I figured it was another gimmick destined to become a very expensive clothes hanger. But then you actually sit on it. Or jump on it. Or try to pull those resistance bands while your quads are screaming.
It’s weird. It’s compact. And for people trying to squeeze a metabolic blast into a 15-minute window between Zoom calls, it’s surprisingly effective.
We need to talk about the "2 cords" part specifically. Most people get confused here because there are different versions of the Fitt Cube floating around. The standard model—the one that actually makes sense for home use—relies heavily on those dual resistance bands to bridge the gap between simple plyometrics and actual strength training. Without the cords, you’ve basically just bought a very sturdy, multi-sided box. With them? You’ve got a cable machine that fits under your coffee table.
Why the Fitt Cube HIIT machine 2 cords design actually works
High-Intensity Interval Training (HIIT) is built on the idea of maximal effort in minimal time. The Fitt Cube is a literal 45cm cube designed by New Image to hit every pillar of that philosophy. You’ve got a step side, a bench side, a platform for jumps, and the resistance cord attachment points.

Balance. If you’re doing a seated row or a bicep curl on a single-cord system, your stabilizer muscles have to work overtime just to keep you from tilting. The Fitt Cube HIIT machine 2 cords configuration allows for symmetrical loading. You can do chest presses, flyes, or even wood-choppers with a level of resistance that feels "cleaner" than a single bungee. Each cord typically offers about 7kg (roughly 15.4 lbs) of resistance. That doesn't sound like much to a powerlifter. However, when you’re doing high-rep burners at the end of a Tabata circuit, that 7kg feels like 70.
The genius is in the 10-plus positions. You aren't just standing there. You're using the cube's own weight—which is about 15kg—as an anchor.
The physics of the "Little Black Box"
Most home equipment fails because it's too light. If you try to do a door-anchor resistance band workout, the door creaks or the band snaps back and hits you in the face. The Fitt Cube doesn't budge. Because it’s a steel-framed box, your body weight keeps it pinned to the floor.
Think about it. You flip the cube to the "Power" side to do box jumps. Then, you immediately flip it to the "Strength" side, sit down, grab those two cords, and go straight into shoulder presses. No rest. No adjusting plates. That's how you keep the heart rate in the anaerobic zone. It’s basically a circuit training gym shrunk down into something you can shove in a closet.
Breaking down the cord resistance
Let’s be real: resistance bands have a "power curve." Unlike a dumbbell, where the weight is constant, the Fitt Cube HIIT machine 2 cords provide more resistance the further you stretch them.
This is great for joint health. It’s less stress on the start of the movement (the "bottom" of the rep) and max tension at the peak contraction.
- The Lat Pulldown: You can sit on the floor, anchor the cube with your feet, and pull the cords toward your hips.
- The Seated Row: Use the built-in bench side, plant your feet against the frame, and work the mid-back.
- Tricep Extensions: Flip it so the cord anchors are low, lean over, and kick back.
One thing people hate? The cords aren't infinitely adjustable. If you’re 6'5", you might find the "top" of the range of motion gets a bit tight. If you're 5'2", you might need to wrap the cord once around the handle to get the tension to kick in earlier. It’s a bit of a DIY fix, but it works.
Is it actually "Human Quality" cardio?
Let’s look at the science of HIIT for a second. Dr. Izumi Tabata’s original research focused on 20 seconds of ultra-intense work followed by 10 seconds of rest. The Fitt Cube is built for this.
I’ve seen people try to use this for long-form cardio. Don't do that. You will get bored out of your mind staring at the floor while doing "steps" for 45 minutes. That is not what this machine is for.
The Fitt Cube HIIT machine 2 cords is for the person who wants to sweat so hard they can’t breathe after 12 minutes. You rotate through the sides:
- Box Jumps (Plyo side) - 30 seconds
- Seated Resistance Rows (2 cords side) - 30 seconds
- Mountain Climbers (Grip handles) - 30 seconds
- Step Ups (Stepper side) - 30 seconds
Repeat that four times. You're done. Your metabolism is spiked for the next several hours due to Excess Post-exercise Oxygen Consumption (EPOC).
Where the Fitt Cube falls short
No piece of equipment is perfect. Let's be honest about the Fitt Cube.
The "stepper" component is... okay. It’s a mini-stepper. If you’re used to a StairMaster at the local Mega-Gym, this is going to feel like a toy. It has a short range of motion. It's meant for quick, rapid-fire steps to keep the heart rate up, not for a long-distance trekking simulation.
Also, the built-in monitor is basic. It tracks your reps and time, but it’s not going to sync with your Apple Watch or provide 4K scenic views of the Swiss Alps. It’s a digital counter. That’s it.
And the cords? They are durable, but they are rubber. Over two or three years of heavy use, they will eventually lose some of their "snap." The good news is that they are replaceable, but it’s something to keep in mind if you’re planning on passing this down to your grandkids.
The "2 Cords" vs. the "No Cords" versions
You might find some older or "Lite" versions of the cube that lack the resistance bands. Avoid them.
The whole point of the Fitt Cube HIIT machine 2 cords is the versatility. Without the resistance elements, you lose the ability to do any meaningful upper-body pulling movements. You're left with pushing (push-ups on the handles) and legs (jumps/steps). Adding the cords completes the "full body" promise. It allows for bicep curls, upright rows, and lateral raises. It turns a box into a gym.
Real-world durability: Will it break?
The frame is steel. You could probably drop it off a truck and it would be fine. The padding on the "seat" side is surprisingly thick, which is a mercy for your tailbone during Russian twists.

The most common "failure" point isn't the machine itself; it's the floor. Because it’s a compact cube, if you're doing aggressive box jumps on a hardwood floor, it might slide an inch or two. Get a cheap rubber mat. It saves your floor and keeps the cube anchored so you can focus on the workout instead of chasing the machine across the room.
Practical Next Steps for Your Workout
If you've just picked up a Fitt Cube or you're about to hit "buy," don't just wing it. The biggest mistake is trying to treat it like a traditional weight bench.
Start with the "30-15-30" rule. Choose one cardio side (like the stepper) and go for 30 seconds. Take 15 seconds to flip the cube to the cord side. Do 30 seconds of resistance rows.
Focus on the "Flipping" flow. The Fitt Cube is designed to be rolled. Learn the sequence. If you know that the "Step" side is opposite the "Power" side, you can transition faster. The less time you spend looking for the right face of the cube, the higher your heart rate stays.
Check your cord tension. Before you start a heavy set, pull the cords to their max length once just to make sure they're seated properly in the clips. You don't want a handle popping off mid-rep because it wasn't clicked in after you unboxed it.
Integrate "Off-Cube" movements. Don't feel like you have to stay touching the cube the whole time. Use it as a marker. Do a set of bicep curls with the Fitt Cube HIIT machine 2 cords, then drop the handles and do 10 burpees over the cube.
This machine is a tool for intensity. It’s not a magic box that builds muscle while you watch TV. You have to put in the work. But if you're short on space and hate the idea of a treadmill taking over your spare bedroom, this 45cm steel box is probably the smartest piece of engineering you can put in your house.

Get a mat, grab the handles, and start with a simple 10-minute circuit. You'll realize pretty quickly why those two little cords make all the difference.
