The lightest flywheel device yet, train with constant resistance throughout an entire range of movements and exercises with an unlimited load or eccentric overload, with just 4kgs.
We’ve made what every fitness professional needs in their life, this is the RackFly.
Cable machines are regarded as a popular device at the gym, especially for strength training. If your objective is to improve muscular definition and strength, its most likely that you’ll cross paths with one or two exercises with cables.
However, cables can't provide eccentric overload, thus hindering your muscle adaptation. Cables can’t train you at both high speeds and high loads over the full range of movement, thus neglecting your body the opportunity to absorb higher forces. Cables don’t provide constant resistance, nor can they mimic the velocity of your movements.
And finally, cables cannot fit into your lifestyle (unless you plan on moving into the gym?) thus failing to become a transportable device able to be provided anywhere and anytime. For those of us that need consistency when training- whether that be athletes, body builders or dedicated gym goers- devices such as cable machines are just too big and impractical to take with us on our journeys.

For The Physical Therapist Rehabbing Clients
You never would have thought you could fit an entire gym in your office until the Exerfly RackFly. Office (and wallet) friendly, the RackFly’s compact design fits into any small space, meaning you won’t be needing to buy multiple pieces of equipment or rent a large space for a gym. The Exerfly RackFly is particularly advantageous for shoulder or upper body rehabilitation.
Designed for dynamic movements, the RackFly facilitates the rotational exercises necessary for shoulder or rotator cuff exercises. Proven to show significant benefits for injury prevention as well as injury management, the RackFly’s Flywheel technology involves constant resistance, allowing for a fuller training regime that targets all parts of a movement for a rounded, quick recovery.
With traditional weights, the weight is static, so resistance is only felt in the concentric phase. Take a bicep curl, for example. Typically, you pull a weight from your thigh to your chest in a circular motion, experiencing resistance as the weight comes up towards you.
Once the weight has passed 90 degrees, the resistance shifts and you are pushing the weight against gravity, which often leads to suboptimal form, as the body adjusts to the changing resistance. When lowering the weight, you’re no longer pulling against gravity, so there is less resistance and it feels much easier.
With Flywheel training, resistance is felt on the way up and the way day, stimulating the eccentric phase of movement. When engaging in flywheel training, the individual uses their force to spin the flywheel, then to slow the flywheel’s momentum.
When pulling the flywheel, it pulls back with the same force, allowing users to control resistance through the modification of the flywheel inertia and the force production of the users.
Exerfly was built on relationships, and has a long-standing collaboration with elite athletes across the globe from which we implement feedback and suggestions into the design of our equipment.
So, we created a one-of-a-kind transportable device that creates, tracks and measures your progress with eccentric overload- the RackFly.
Maximize your workouts with our in-built sensor and Exerfly app. With an all-new app and in-built sensor tracking data points at 4,000 times per second, now you can monitor your workout data in an easier, more efficient way and receive feedback on every single rep.
Calculate ROI on actual results, track statistics such as force, power, speed, and torque, and watch your performance improve with quantifiable data that allows you to maximize your training and results.
The RackFly can also include Exerfly’s advanced motorized technology, meaning you can take your workouts to the next level with an increased resistance between 1-80% in the eccentric phase.
Overloading eccentrically can be highly beneficial in many different areas, including muscle hypertrophy and injury prevention. For example, if the user selects a 10% boost, then whatever energy they put into the concentric phase of the movement will be amplified by 10% in the eccentric phase.
With the Exerfly RackFly, you can train real sports movements with ease. The RackFly is often a favorite of sports teams based around movements such as throwing, swinging a bat, rowing, punching, or other rotational based movements.
Combined with its small size, it makes the perfect addition to home gyms or traveling sports teams needing to round out their setup with elite equipment.
You can add up to 10 red flywheels for slow isometrics, and to increase the motorized technology, so you have no limit on the load you want to work with.

Both the exerfly portable and platform products will continue to be beneficial for our basketball players. The unique resistance profile can facilitate higher impulse-oriented loading at troublesome joint angles, such as deeper ranges of flexion during squatting exercises.
Traveling with the Exerfly Portable has added immense value to our training on the road. The type of resistance provided by the flywheel is just something that is hard to mimic without the equipment itself. The Portable is extremely easy to set up and break down, and has stood up against the rigors of NBA travel.
The versatility of the Exerfly Platform is unmatched by any other piece of flywheel equipment on the market. Firstly, being able to use 1 or 2 straps is a huge advantage. Unlike other equipment with 1 strap , the Platform can be better set up for things like deadlifts with 2 separate handles or a shoulders elevated hip bridge with a straight bar. This has allowed us to utilize the flywheel stress with most of our exercises.
The Platform motor feature also has huge potential to enhance our training in our foundational exercises like squatting and hinging. Basketball players are subjected to immense forces as they move into and out of positions of ankle, knee, and hip flexion. The Platform motor can increase the speed of the spinning wheel during the eccentric portion of the exercise, facilitating higher force outputs that would be hard to mimic using any other method.
I believe the Exerfly products provide a type of stressor at an intensity that will allow us to make serious improvements in our KPIs.
We are lucky that the Exerfly company has been responsive, open minded, and eager to innovate using the feedback of coaches in the field. They are already ahead of most other companies in this particular space, and we are excited for the continued evolution!
“The sports that I work with predominantly are very measured, so physical performance is a prerequisite. Trying to develop that physicality has become somewhat of an obsession of mine, and I like to find ways of doing things better – which is why I use Exerfly.”
“The athletes I work with are speed and power athletes, so physical performance is a prerequisite. We’ve been using Exerfly for several years now, and the ability to train these high power qualities in different planes, rotationally, and in different aspects has been extremely advantageous. I’m using it because it works.”
“The ability to take Exerfly and travel with it has been something that I’ve never seen before, and there’s a lot of elite athletes around the globe now using Exerfly. And that’s a testimony to the company, that Exerfly has been flexible and has continued to develop.”
“Most of the movements we do in sports are not strength orientated, they’re power orientated. And most of that is high-velocity power. For somebody to jump high or run fast, it’s not a slow grinding strength like you might see in powerlifting – it’s elastic power and high-speed muscle power, and you can train both of these with Exerfly.”
When it comes to strength training equipment for my athletes, I am of the minimalistic camp. I really like the adjustable rack mounted flywheel from exerfly. First of all for its versatility as the adjustable height opens up many possibilities for different exercises as well as stressing different portions of the same exercise. It is also important that the flywheel comes with measuring capabilities and a simple app that tells you what amount of work is done which is not always the case with inertial equipment. I am grateful to exerfly for the quality of their product and the quick customer service they provide despite being exactly on the other side of the world from me.
I like the ability to introduce a different way of training regimen into my schedule and routine. It gives my body a different way of adapting to load and intensity. Exerfly has increased power and endurance during strength sessions and explosiveness. Exerfly equipment has been a great addition to my strength component as well as strength endurance. Full body workouts are very challenging with limitless moderation of effort. I have enjoyed a lot for the communication and introduction to Exerfly and the expertise to get the best out of the equipment.
Exerfly is my equipment of choice in flywheel training technology. The equipment is versatile and easy to use. I have found the rack mounted unity system especially effective in my work with throwers, volleyball players and swimmers. A very versatile tool.
Researchers investigated the influence of a weekly bout of inertial squat resistance exercise offering eccentric overload on lower limb muscle power and patellar tendon complaints on over 80 basketball and volleyball players of both sexes.
They found that adding a weekly eccentric overload squat training bout to a regular basketball and volleyball exercise routine enhances lower limb muscle power without triggering patellar tendon complaints.
