OMG MY NEW GYM PARTNER. I have a small one bedroom apartment so I take it with me to the gym. I feel the results when I use it. I'm seeing results and I've only had it for a week. I use it daily. I love it. Best addition to my workout — I get more sit-ups and because it's almost like my back is being massaged, I don't have lower back pain like I used to."

What Makes It Different
Spring Assistance That Actually Works
Most ab machines just hold your feet down and let you grind through the pain. Corux™ actively assists you on the way up — the high-strength torsion spring absorbs the strain and puts the isolation exactly where it belongs. In your core, not your neck or lower back.
Built To Take A Beating
A 3cm heavy-duty steel frame and 2cm high-strength torsion spring that has been stress-tested through thousands of cycles without deformation. This isn't plastic held together with wishful thinking. It supports up to 330lbs and it won't wobble, creak, or give out mid-rep.
The Only Machine You'll Actually Keep Using
Every piece of fitness equipment you've ever owned became a clothes hanger within a month. Corux™ folds flat in 2 seconds and slides under the sofa. Out of sight until you need it. No guilt, no tripping over it, no excuses.
6 Exercises. 10 Minutes. Real Results.
Sit-ups, push-ups, glute bridges, scissor kicks, triceps, forearm work — all printed right on the pad. No app. No subscription. No guessing. Just pick up where you left off and get it done.
FAQs
Absolutely. The spring-assisted mechanism was specifically designed so that someone who hasn't exercised in years — or ever — can complete their first session without frustration or injury. Start at Level 1, get comfortable, and progress at your own pace. The machine does the hardest part until your body catches up.
Most customers feel the difference after their first session — that deep core soreness the next morning tells you muscles were activated that haven't fired in years. Visible results like a firmer, more defined midsection typically show within 2–4 weeks of consistent daily use. Ten minutes a day is genuinely all it takes.
This is one of the most common reasons people choose Corux™ specifically. The 3cm padded base eliminates the hard floor pressure on your spine, and the spring assistance means your lower back never has to compensate for a weak core mid-rep. Multiple customers with chronic back conditions use it daily and report relief rather than aggravation. We always recommend checking with your doctor before starting any new exercise program.
Six in total — all printed directly on the pad so you never forget them. Sit-ups, push-ups, glute bridges, scissor kicks, forearm and bicep work, and quads and glutes resistance training. It targets arms, back, core, legs, and glutes in a single piece of equipment.
None at all. Open the box, place it on the floor, start your first rep. No tools, no instruction booklet, no wasted time. It arrives fully assembled and ready to use immediately.
There are 3 levels. Level 1 provides maximum spring assistance — ideal for beginners, seniors, or anyone returning from injury. Level 2 offers balanced resistance for intermediate users. Level 3 reduces the assist to a minimum, putting maximum demand on your core for advanced training. You can switch between levels in seconds.
Almost none. When folded it collapses to just 5.7 inches tall — slim enough to slide under a standard sofa, fit in a car boot, or tuck into any corner. The footprint is 18.5 x 19.88 inches, roughly the size of a large laptop bag laid flat.
It's light enough to carry with one hand. Customers regularly take it to the gym, to the office, on trips — one customer takes hers from her apartment to the gym floor daily. It goes where you go.
