“I knew the Nurvani Plate was working when my friends started asking, ‘What are you doing? You look stronger and more toned!’
It’s only been a few weeks, but I can already see and feel the difference—especially in my legs and core. Just a few minutes a day, and it’s become my favorite part of my routine!”

How to use

🛠️ How to Use the Sit-Up Assistant Device

Step 1: Choose a Flat Surface

Make sure you're using a clean, smooth floor such as tile, hardwood, laminate, or marble. Wipe the surface to remove any dust or moisture for maximum suction.

Step 2: Attach the Device

Place the suction cup flat on the floor.
Firmly press down and lock the lever to activate suction. You should feel it grip tightly.

Step 3: Adjust the Foam Bar (if applicable)

Some models include an adjustable height setting. Set the bar height so it feels snug but comfortable on the top of your feet.

Step 4: Position Your Feet

Slide your feet (with shoes or barefoot) under the padded foam bar. Ensure your heels are close to the base for maximum stability.

Step 5: Begin Your Workout

You're ready to go! Perform sit-ups, crunches, leg lifts, planks, or even resistance training using the foot support.

✅ Pro Tips:

For maximum suction, use on non-textured floors.

Always double-check the lock lever before beginning exercise.

To remove, gently lift the lever and pull the tab on the suction base to release.

What Our Customers Are Saying

⭐⭐⭐⭐⭐ "Finally, a core trainer I’ll actually use consistently!"

By Megan A., Verified Buyer

I’ve tried so many ab workout tools in the past, and they all ended up collecting dust or being too bulky for my space. This sit-up assistant, though, is a total game-changer. It’s compact, easy to set up (literally takes seconds), and it sticks incredibly well to my tile floor. I was honestly shocked by how stable it feels.

The padding is just right — soft enough that I don’t dread putting my feet under it, but firm enough to hold me in place during reps. I’ve been using it every day for two weeks and I’m already seeing more tone in my core. I even use it as a foot anchor when stretching or doing resistance band work.

If you're like me and need just a little support to stay committed to working out at home, this is the perfect tool. Highly recommend it for anyone who wants better results from their core training without a gym membership or expensive equipment.

⭐⭐⭐⭐⭐ "As a mom of two, this is a godsend for my home workouts."

By Rachel T., Verified Buyer

I barely have time for myself these days between work, house chores, and taking care of my two kids. Going to the gym is out of the question — so having simple, effective equipment at home is everything. I came across this sit-up bar on TikTok and decided to give it a try.

WOW. I can do sit-ups without my feet flying up or asking someone to hold them (which, let’s be real, never actually works). The suction is surprisingly strong, and it holds on both my hardwood floors and even the laminate in my kitchen. I also use the resistance band to stretch or do arm work while the baby naps.

It’s lightweight enough to move from room to room, and it doesn’t look bulky or ugly, which matters when you’re tight on space. I love how this has helped me regain my core strength postpartum. It’s small, but mighty. Worth every penny!

⭐⭐⭐⭐⭐ "This is the underrated fitness tool you didn’t know you needed."

By Jordan C., Verified Buyer

I’ve been into fitness for years and thought I had everything I needed — dumbbells, kettlebells, yoga mats — you name it. But this little sit-up assistant surprised me. I bought it kind of on a whim after seeing a few people mention it online, and now I use it almost daily.

First off, it anchors you perfectly for ab exercises. No more using a couch or holding onto your dresser. Second, it’s great for improving your form. I noticed that with this device, I don’t strain my neck or hip flexors as much during sit-ups and crunches. It keeps me grounded and allows for more controlled movement.

It also travels well — I brought it with me on a recent business trip and used it in my hotel room without any issues. Suction worked well on both tile and hardwood.

Whether you're a beginner or advanced, this is one of those tools that elevates your routine without taking up space or requiring a learning curve. Highly recommended.
