Introducing Exerfly’s Motorized Technology

Eccentric Resistance Boost

Exerfly’s Motorized Technology gives athletes the option to add an additional eccentric overload of up to 80%, based on the force put into the concentric 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.

How does it work?

Eccentric Max utilizes smart electric motor technology to provide more energy to the flywheel in the eccentric phase of a movement, based on how much energy the user produces in the concentric phase rep-by-rep.

For example, if the Eccentric Overload Boost is set to 20%, the flywheel will be given 20% more energy in the eccentric phase of a movement than it had in the concentric phase. The flywheel will spin faster, and the user will get an increased eccentric overload. The statistics in the app will reflect this.

How do you set it up?

Exerfly's Motorized Technology can be added to the Exerfly Platform or Exerfly Rack-Mount. Through the Exerfly app, athletes can simply add an eccentric overload of up to 80%.

Once on the machine, the equipment will beep several times, warning the athlete the machine is about to start. The beeps will speed up, and once the athlete is in position, the Motorized Technology will kick in during the eccentric phase with the selected overload.

Who is it for?

Exerfly’s Motorized Technology is perfect for trained individuals who want to increase their eccentric strength and overall speed and power. Because you can train at a quick pace and with constant load throughout the entire movement, exercising with the motorized option is a powerful addition to your workout.

Ranging up to 80% in eccentric overload, Exerfly’s Motorized Technology allows elite athletes to achieve a level of unparalleled forceload for strength and conditioning. Our motorized option is ideal for elite athletes performing at a high level who are looking to boost their results and train supramaximally.

Why should I use the eccentric overload?

This advanced motorized technology is extraordinary for achieving and measuring high levels of eccentric overload. Traditionally, achieving eccentric overload is possible using assistance via the hands of a partner or relaxing specific braking following the full range of motion during the concentric phase. However, you are not able to select how much you are going to eccentrically overload the user.

With Exerfly's motorized technology, high loads of eccentric force is easily achievable and managed in a safe and measurable way. The eccentric overload force requires no external parties for help and can be applied throughout total movements, with the option of supramaximal if needed. Used by elite sports teams, athletes and strength trainers around the world, this motorized technology has seen success implemented in sports that require fast, explosive and powerful movements.

Why did we innovate Exerfly's Motorized Technology?

Being a New Zealand company, we are part of a small population, so we've had to be very innovative with our equipment when competing on the world stage in elite sport. When discussing with New Zealand leading coaches, it became apparent that the biggest point of difference and highest performance increases were when the eccentric phase was targeted and boosted for certain exercises and periods.

Athletes with traditional flywheel training are limited to a certain point, but are able to choose the eccentric overload for exercises with our equipment. We work with a variety of different sporting professionals, so we received an overwhelming positive response from coaches and athletes alike.

We responded to the demand of adding Exerfly's motorized technology to the Rack Mount as well as the Platform, and now athletes are able to now re-create a range of different sporting movements such as boxing punches and shot put throws with our equipment. This was a total game changer within the industry, as it had never been done before, and resulted in increases in sports performances and motor control.

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.
