The Better-Fly - Full Body Isolation Exercise Cuffs (Pair)

★★★★★+ - Finally made my chest—not my triceps—the limiting factor

This is one of the rare gym accessories that did not merely make an exercise slightly more convenient—it materially changed how effectively I could train the target muscle.

My biggest problem with cable chest exercises was that my triceps and arms would give out before my chest was actually close to failure. I could tell that my chest still had more work left in it, but the set would end because I could no longer maintain the position or continue transferring the resistance through conventional handles. I tried changing angles, handles, machines, and technique, but the same basic bottleneck kept returning.

The Better-Fly solved that problem, immediately.

By transferring the cable resistance through the cuffs instead of requiring me to hold and control everything through my hands and triceps, it allows me to concentrate on the movement that actually matters: bringing my upper arms together and contracting my chest. I no longer have to spend most of the set thinking about whether my arms will fail before the muscle I am trying to train.

During my first serious chest workout with The Better-Fly, I was able to progress through substantially higher resistance settings and continue until my chest—not my triceps—was finally the muscle approaching failure. The difference was not subtle. I felt much clearer tension in my chest throughout the movement, obtained a much stronger chest stimulus, and could focus on squeezing and controlling the contraction instead of fighting an unrelated arm limitation.

The following day, I had the clearest and most significant chest soreness I had experienced from this type of cable fly training. Soreness is obviously not the only measure of an effective workout, but in this case it matched exactly what I had felt during the sets: the intended muscle was finally receiving the workload instead of being protected by an earlier triceps bottleneck.

That is the real value of this product. It is not simply a padded alternative to a normal cable handle. It changes where the limiting factor occurs. For anyone who feels that their hands, forearms, or arm muscles are ending a set before the target muscle has been trained hard enough, The Better-Fly may completely change the usefulness of cable exercises.

It is also far more versatile than I initially expected. In addition to chest fly variations, I have used the cuffs for cable-based lower-body and glute-focused movements. They make an ordinary cable station capable of supporting a much wider range of exercises, which is especially valuable in a busy gym when the exact machine I planned to use is occupied.

The design is simple to integrate into a normal workout, the attachment hardware feels substantial, and the cuffs remain secure once they are positioned and adjusted correctly. There is a brief learning curve in finding the best placement and tightness for each movement, but once that is established, the cuffs allow me to focus almost entirely on the target muscle.

Customer service was also excellent—responsive, thoughtful, and genuinely helpful.

I have purchased many small gym accessories that ultimately turned out to be optional conveniences. The Better-Fly is different. It solved a real biomechanical bottleneck that had been limiting my training, and it has already become a regular part of my chest workouts.

I would absolutely recommend it to everyone. Highly recommended.

LOVEEEEE the betterfly Cuffs!! I do a lot of cable kickbacks for glute building and THESE are fire!!! 🔥 the isolation it has on the Maximus is TOP NOTCH. I also love how versatile these cuffs are!! I can hit an upper day with them as well and they create more isolation on the muscle you are wanting to target such as lat pull downs, chest flys, single arm lat pull downs, and so on! I RECOMMEND TO ALL MY CLIENTS. 🙌🏽🔥

Happy to be stronger, and a lot more pain free in my joints, especially my hands and wrists.

I absolutely LOVE these cuffs. Not only are they durable,the quality is A1 and they can be used for multiple different exercises/workouts. I use them for both leg day and upper body. The thickness of it is also what I love, unlike the previous band I was using, these are stronger, more durable, and super simple to use. Recommend 10/10!!!

After a major achilles surgery, I was starting to become really depressed by the decrease in strength and mobility that I was experiencing. Even months into recovery, ankle straps would dig into my scar tissue and make things very uncomfortable after only a few reps. Luckily, I found the Better-Fly, which has been an absolute GAME CHANGER. I can do all of my lower body cable work completely pain free, and I can even do it from home and still spend time with my kids! It's nice to know that my entire lower body doesn't have to suffer just because of a tendon injury! This may potentially save me multiple long drives to physical therapy. 10/10 would recommend the Better-Fly to anyone with an ankle injury.

Love using the betterfly, it’s everything I expected it to be, made with quality materials with a soft grippy inner, and hard outer shell to allow it to hold shape when in use. Being able to resize it opens up the door to more exercises but boy does it feel great for cable flys!

Bottom line. You can use more weight using these with pinpoint focus than without. Additionally less joint pain. Five stars!

I’m so grateful for that product which allow me get back to workout and give me hope back 😍🥹🫶

As someone who has their own branded fitness app that trains women worldwide/I HIGHLY recommend the butterfly attachment. It hands down has been the best attachment to help activate my glutes over products I have bought in the past from other companies.

fantastic products for individual training

The BetterFly is a top tier attachment. Synches up, non slip, and padded for comfort! Makes removing joint action and weak points from tons of lifts and allows you to focuson working the muscle you’re targeting, only! If you’re a serious lifter, you need to give this a shot!

I have my degree in exercise science, I’m a Certified Strength and Conditioning specialist, Ortho-Kinetics Specialist Trainer, and have been training individuals and teams for over a decade now. If you want to level up your hypertrophy training, The Betterfly is by far the best cuff on the market for isolating joint actions. It’s much more comfortable, versatile, and very well built with high quality materials. It will completely open the door for many different variations of isolation movements and truly allow you to target the muscles you want to train and build your dream physique. Chest has always been a weak point for me but I have noticed some rather impressive gains in a short amount of time implementing the betterfly into my routine. If you’re on the fence about purchasing it, GET IT, you will not be disappointed. Of you don’t take my word for it let the EMG comparisons speak for themselves! -Quinton

If you are looking to take care of your joints and at tge same time get that true mind muscle connection then The Better Fly is a perfect addition to your workout. My chest has never had this kind of stimulation in 40 years of lifting. Highly recommended!

It‘s a really high quality device. I love it for chest flys, abs and especially for lateral raues und rear delt fly.

Very effective and appreciated

I just used my Better Fly for the first time today. I found it to be absolutely amazing! I suffer from a lot of joint pain. With the Better Fly, it seems to eliminate most of the pain while working out. You can immediately tell how much more it works your muscles. 👍🏼Frank Trombetto

The Better-Fly Cuffs are very comfortable and do a great job of improving the mind-muscle connection. I have been using ankle weights and ankle straps with many of my clients but I believe the Better-Fly cuffs do a better job of training the glutes and hips due to their location at or near the knees, which provides a better feel and more intense work. The Better-Fly cuffs are also great for lat pulldowns. The quality of the cuffs and the design process make these a great product for everyone who trains. Definitely recommed!

This is an absolute revolution!! I have never worked cables like this before. an absolute game changer! There are so many creative ways to use The Better-Fly. The videos don't do it justice; you got to try it for yourself!! 🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥

Honestly a fantastic product! Been using it for a lot of my work outs to strengthen my chest and legs. Learning how to use it for my back as well! All in all great way to work out! I would highly recommend the betterfly to anyone.
