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

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.

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!
I ordered my jay flex pull up bars last week and received them a few days later. Great service. Fast shipping and quality equipment. Ive been using them for 7 straight days and Im starting to feel a difference. Ill be ordering some more accessories for them as well.
Maybe I'll actually achieve unassisted pull-ups with the help of these bands. Love them.
So easy & convenient!
I really like them. I bought the bundle and couldn’t be happier. The ez curl bar is perfect, the straight bar has been great and the kettlebell is handy.
It doesn't fit my Bowtech as your ad states
Great for small spaces, and idea for older adults who can use these systems without a lot of assistance.
Love this curl bar. I highly recommend it for your work outs…..
The black grips that protect the door jam are coming off and may eventually damage my door. It also pinches my skin if I hold it a certain way attaching it to the door. If they could fix these things it would be perfect
Works great!
Love this! Works so well and makes training so much better with how many movements you can use it for. 10/10 recommend!
The crossgrips fit just right on my door I have been struggling on the old pull up bar that used to hang on my door frame because it was to long but with the crossgrips I have space and it's easy to fold back up and put away. I RECOMMEND
I am loving it so much!
The rubber ripped the 2nd time I used them.
The replacement is missing the loop for hanging. The part that has a lot of rust on the original. I sent a message, but haven’t heard back
The jayflex hyperbell straight bar is an amazing product and the originality behind the idea of using your own dumbbells is unparalleled. The bar itself is very sturdy and the 200lbs limit is more than enough weight I'd ever use for it (I'm using Snode AD80s). After a few uses, I assessed the practicality of the product as it pertains and fits into my own workout split. PROS 1. Rigidity and strength. I must say the bar itself is engineered to last. I'm aware the foam inserts can be replaced after wear and tear (after I found that out it was the final check box for me to purchase). The plastic nuts to tighten it seem to hold up just fine so far (I've attached up to 160lbs thus far). It does make a loud *CLICK* on one of the sides, when initially lifted off the ground with that much weight. I'm hoping it's just a "break in" period and not defected. It seems okay but I will monitor it. CONS: 2. The rubber grip could probably be replaced altogether by a pattern of knurling instead, and maybe swap the plastic nuts with aluminum. Definitely would have been a 5/5 stars from me with these two adjustments. Another pet peeve that you guys might want to consider on a more "premium model option" of this product (maybe verses the current standard model?) is the option of *swivelling clamp ends" so the low center of gravity can always be swivelling to the ground during a repetition. Now, I personally like the "wonkier* feeling of doing curls and having to lap the entire curve of the dumbbells into one rep (it really slows the rep down and forces you to really work it), but others might not. Find a way to swivel the end clamps; and I think the broader market for this sweet little bar will increase tenfold. Just my humble opinion. Overall: FANTASTIC PURCHASE for my little indoor office / home gym. Glad I found this and didn't go with some knock off version on Amazon. Thank you!
The curling bar fits into my mostly dumbbell home gym and easily adds exercises that I can add to my workouts. I am happy with my purchase.
Would be 5 stars but hard to pull apart to get over door jam
Love the ease in assembly. Depending on what I want to work on I can easily switch based on me needs. I love that I can do more than just barbells and it has really helped my home workout.
Edit 2: the attachment hook broke and I can no longer safely anchor the tool. Works well but would be better if came with the attaching clamps and anchor points.
The system is easy to work with and comes with well-built components. I’ve added a lat pull bar and lower pulley system. It breaks up the workout routine having more options.
Great tool to enhance your home gym! Holds up to 200lb very well. I love how simple it is. It has elevated my routines. The material is great and feels firm. No complaints
Works great with my Bowflex weights
Hyperbell EZ Curl Bar- BACKORDERED DUE TO HIGH DEMAND, SHIPS 5/22
Love the bar! Can do so much with it. Well built.
I love it and the will deal 🤝
I live in a 150 year old home, and the door frame is larger than younger homes. I can barely fit my fingers through to grip the bar, and I can’t fit them to do a hammer pull up. The ab straps are great though.

🌟The Jay Flex Ab Straps have been a game-changer for our gym! All of our trainers, including myself, absolutely love them. We use them almost daily, and the durability and quality of the material are top-notch. Plus, the defined color fits perfectly with our gym’s theme!Thank you, Jay Flex, for creating such a superb product! These straps have become a key addition to our inventory of fitness equipment , helping both our trainers and clients elevate their fitness journeys. We’d love the opportunity to partner with you and showcase your amazing gear even more! Taking fitness to the next level together! 💪
5 star review because I think the concept is awesome, but in the next version of these please make them adjustable for door frame thickness, I have them fully expanded and taped to fit my door frame and it is still loose. The grip material could also be made to be more comfortable. If my door frame was standard size there would be no problems.
Love it! It’s so portable & easy to use. This takes the place of a whole set of different size kettlebells! Such a smart product:-)
I was really hoping to use this with the CORE Fitness Adjustable Dumbells I already have. The website had said it worked with them at the time of purchasing them and I had watched videos of other people using them with it. Unfortunately the handle is JUST barely too big on these dumbells for it to fit. My wife's generic rubber Walmart Hex dumbells fit (like in the picture) but they're kind of loose and move up and down when working out. It works but not as elegantly as I expected. It is well made but a bit short in length. I really hope Jayflex will consider making different sized clamps for different sized dumbells. It seems like an easy fix since the clamps can be quickly removed from the bar. Then people could choose the clamp that works with their dumbell when purchasing it and more people could buy it. I'm not sure if I'll keep it or go through the trouble of returning it. I dont want to make my simple set up bigger by collecting separate dumbells that fit this bar just to use with it.
They work great. Stable when doing pushups and chinups. Easy to put on and take off a door frame. Did't leave any marks.
Store owner replied: Hi Daniel, Thank you for the great review! We’re glad to hear the crossgrips feel stable during workouts and that the easy setup and no-mark design are working well for you. We appreciate your support!
Thanks for getting me a replacement so quickly. The new unit is fantastic!
Store owner replied: Hi Karambir, Thank you for your patience throughout the replacement process! We’re happy to hear the new crossgrips are working fantastic and meeting your expectations!
Love these bars, super easy to use!
Store owner replied: Hi Jessie, That’s exactly what we hoped for — effective and easy to use. Thanks for your support!
Love the barbell. It’s well constructed and allows me to do more workouts at home.
Store owner replied: Hi Oluwaseyi, Thank you so much for the great review! We’re thrilled to hear you love the hyperbell and that it’s helping you expand your workouts at home. We put a lot of focus into quality and durability, so it’s great to know that came through. Enjoy your training, and thanks again for your support!
