THE PROBLEM
Don't Let Your Home
Don't Let Your Home
Gym Hold You Back.
Five things every home lifter knows by heart — and the lifts they keep you from doing.
Traditional Barbells Don't Fit Home Gyms
Long bars scrape the walls and a full rack with plates eats your whole garage.
Stuck Without Real Barbell Lifts
No bench, squat, or deadlift — and two-dumbbell presses get dangerous past 60s.
Can't Push Past Plateaus
Compound lifts plateau the moment your weight options run out.
Training On The Road Is A Struggle
Hotels rarely have more than dumbbells — your routine collapses the second you leave.
INTRODUCING THE BAR THAT FIXES ALL OF IT
The
The
Hyperbell Bar.
The Original Dumbbell-to-Barbell Converter.
The dumbbells you already own become a full barbell in under a minute.
No new weights. No bulky equipment. No drive to the gym. No DIY pipe-and-prayer setup.
Just clamp, lock, and lift — and you've got bench press, squats, deadlifts, rows and presses on demand, in the space you already have.
The missing piece between "I have dumbbells" and "I have a real gym."
HOW IT WORKS
Three Steps.
Three Steps.
Under A Minute.
Every Time.

Lock It.
Twist the locking collar shut. The harder you load it, the tighter it grips. Patented clamshell engineering, drop-tested to 200 lbs total.
03
Lift It.
Bench. Squat. Deadlift. Row. Press. Curl. 25+ barbell-grade lifts your dumbbells alone could never do — using the gear already in your house.

Questions?
We've Got You.
The most common questions from people right before they hit "add to cart."
WILL IT WORK FOR ME?
Most likely yes. The Hyperbell Bar fits any standard dumbbell with a handle at least 4.5″ long and no thicker than 1.5″.
Confirmed compatible: Bowflex SelectTech 552, hex/rubber hex, Peloton, JaxJox, MX Select, CORE Fitness, Weider, Snode, NordicTrack (orange), and Bowflex 1090s purchased before 2010.
Not compatible: PowerBlock, NuoBell, FitRx, Bowflex 1090s after 2010, and neoprene-coated dumbbells.
For most home lifters, yes — 200 lbs total covers full progressive overload for bench, squat, deadlift, row, and press. If you're already moving 200+ lbs on the big lifts, you're in advanced territory. For the 95% of home lifters between beginner and intermediate-advanced, the Hyperbell Bar has years of progression in it.
WILL IT HOLD UP?
No — and this is the part most people don't understand until they try it. The patented clamshell locking system tightens harder under load. There's no torque, no thread, no way for the clamp to back off mid-rep. Every bar is drop-tested under real load before it ships, backed by a 2-year warranty.
Hyperbell is over-engineered on purpose. High-end steel bar. High-strength polycarbonate clamps. Full system drop-tested, fortified, and built for daily, rugged use. If anything fails within 2 years, we replace it free.
WHAT IF I DON'T LOVE IT?
Send it back within 30 days for a full refund. No questions, no restocking fee, no fine print. If it doesn't unlock new lifts the first time you use it, we don't want your money.
Free shipping on all US orders. Most orders ship within 1–2 business days and arrive in 3–5 business days after that. You'll get a tracking number the moment it leaves the warehouse.

Customer Reviews
Overall rating: 4.3 / 5 from 9197 reviews.
Send all the parts needed. I can't even use the equipment because all the parts did not show up. I sent in a complaint to no avail.
More sturdy and of much better quality than the last chin bar I had. Really impressed with the product.
Normally I don't do these surveys and reviews because I feel very put upon -- every single company asked this every single time you buy anything, always. It's a lot of extra time to put in. You already have my money. What more do you want? I didn't ask for a refund so I must like the thing. You got five stars. Here's the rest of my experience.
It is like having my gym on the go! I love it!
It's a great option for home gym set-ups that don't require any permanent fixtures, but it is a lot harder to actually expand and set up than it should be.
Very good product and design.
Jayflex CrossGrips have been a great addition to our home workouts! They’re compact, easy to set up, and simple to pack for trips. My husband especially enjoys using them for push-ups. He was skeptical that something so small would feel sturdy enough for him at over 200 pounds, but he’s been pleasantly surprised by how supported he feels. I love that they can be used on the floor or attached to a compatible doorframe, giving us different workout options without bulky equipment taking up space.
Overall, I really love these cross grips. They are great for traveling because it brings your pull-up bar wherever you're going. They hang easily on a doorframe, and I can also use them for push-ups. They work really well with my regular workout routine. I don't need to use my giant pull-up bar in the garage; I can just put this on a doorframe and go. So overall, I highly recommend these.
I like that the CrossGrips are very convenient and makes it easy to get in a quick work out. I did not like the struggle of putting them on the door frame. I actually had to have my husbands help, but after they are up and positions I really like them.
Work great with Blowflex Selectech 562
I thought all in all this is a great product for home workout lovers. It is really compact for storage as it takes up less than half the space of usual pull up bars. I was also not worried at all about pulling my door frame down which was a huge plus. One down side is that first installation wasn’t easy but once you get the hang of it, it is pretty quick to put up and take down.
Obsessed with these! They are super compact, easy to fold and store, and make push-ups so much easier on the wrists while giving a killer range of motion.
Overall, a great product for the price, only improvements that could be made would be wider handles and thicker handles.
I absolutely love these JayFlex cross grips. They are super convenient and easy to travel with. I love how compact they are and easy to set up. They really add a new dynamic to my travel and at home workout routine.
These allow me to work out wherever I travel and incorporate more exercises than before when I only had exercise bands. I actually prefer these over bands for upper body workouts because they are so simple to use!
It’s been great so far I use it mainly for decompressing my spine before an arm workout as I have shoulder and spine issues, it seems to be helping a lot to decompress my spine before I do any movement exercise exercises.
Really easy to install and high quality materials. Love it
Very happy so far. The grips, and therefore your body weight, are held up by the door trim. I haven’t pulled any trim off yet! I can hardly do one pull-up unassisted, but the bands work well. I’ll get there! I put the band over both grips so that the assist point was in line with my body.bbthis shortens the band, and also makes it all more stable, rather than having it off to one side.
It takes a little practice setting up, but once set up they are sturdy. I like how easy they are to travel with since they fold up nicely.
Nice to help me workout at home after surgery
I absolutely love the hyperbell cables from JayFlex! Hooks up conveniently to any door. Comes with multiple attachments. Has a spot for you to attach a handweight to be the weight you’re pulling down. High quality. Will be repurchasing!
Good product.
Great fast and works for what I need
These cables are super easy to set up and really adds an awesome dimension to a home gym! You can even take it on the go, all you need is a dumbbell. The various attachments are super nice as well!
Love my EZ curl
Great piece of equipment!
The chin bars should be able to fit all doorways..
Great home workout system! Compact, easy to store and set-up! Definitely recommend!
Super easy cable pulley system to set up. Works well with my dumbbells. I especially love it for tricep workouts. I like the attachments that come with it as well. I think it’s essential for home and won’t take up any space. I already have a pull up bar so it attached to that flawlessly. Overall, great product for my needs.
What an awesome piece of equipment to have in your home. I have mine set up downstairs near my bike and tread so that it’s easy to set up and quickly get in a hardcore workout. I love that this cable set comes with D handles, a bar and a rope. The pulley is made of quality material and makes for a smooth pull thru the pulley system. How great is it that it also allows you to choose different weights for different body workouts.
It works great and I feel good after using it.
Super impressed with these hyperbell cables. They make my workouts so much more versatile. I love that you can transform your dumbbells into a cable pulley system right in your home gym. I highly recommend these
Almost 72. Goal for a pullup, or 10, this year!
I've had these pullup grips 1 week now and I'm loving them. I put them in my master bathroom doorway and I'm averaging 10 to 20 additional reps per day just because of the convenience. So easy to knockout a set a few times a day. They feel really stable and no damage to wall or door frame so far.
Thank you so much , I use it everyday after work to do exercises at home
The description says if it’s door jams 4 1/2 to 7 1/2 inches wide however there is no way to expand the width so it definitely does not fit mine. I have pictures as well.
Easy to clamp onto my dumbbells. Feels very sturdy and well made. For the price you would be silly to not add this to your workout equipment
I am a 74 year old male who lives in a duplex. Though spacious, space must still be used effectively and efficiently. So already having a nice range of Cap dumbbells, and wanting a straight bar, but not enough room to add plates and a rack. Then I saw the Jayflex Hyperbell bar, I knew it would meet my workout needs perfectly, and I was right. It is the best thing since sliced bread. The sturdy construction, simple disassembly, ease of attaching dumbbells, and safe. I use a lot of dumbbell exercises, due to the stabilizing muscles they develop. The Hyperbell Bar is worth every penny. ☆☆☆☆☆ 🤘
I recently purchased the Jayflex CrossGrips, and so far I’ve been very happy with them. I mainly use them for pull-ups, and they’ve made my workouts more enjoyable and versatile. I try to do pull-ups 3–4 times a week, and the CrossGrips have been really helpful in keeping me consistent with my routine. They’re easy to use, feel solid, and give me some flexibility with my grip and exercises. Overall, I’m very pleased with the purchase and would definitely recommend them to anyone looking to add some variety to their pull-up workouts.
I love that they created this since I don’t have a gym membership. It’s well made and I’ll be adding it to my lower body routine! I did notice, though, that I need to find something to sit on that will elevate me a little higher so I can get a greater range of motion. Overall, I’m really happy with it!
