Designed By Those Who Understand RSI.

Our trainer has been designed and created to help those who battle RSI. Unlike exercise routines that only provide mild pain relief, our trainer was made by those who understand RSI and how to battle it. Amongst many programs, therapies and other exercising tools, at 'Persisted' we study how RSI problems occur and how they progress. This has allowed our team to design a trainer which is able to stimulate the arms in the most beneficial way and provide in most cases, a complete relief from all symptoms.ย 

How It Works:

Our trainer works primarily with the use of gyroscopic resistance. Once the user starts spinning, the trainer will start accelerating its core resulting in an increase of resistance felt in the users hands. This resistance affects the hands, wrists, tendons and muscles directly, resulting in a subtle yet effective rehabilitation exercise.

Using the trainer consistently is important for effective pain relief. We recommend spinning for at least 10 minutes a day to ensure a good level of stimulation in the arms. This should be done in intervals as using the trainer for long periods of time continuously, proves to be a challenge!

The spinning technique is easy to learn and very intuitional. Please do not hesitate to contact us with any issues. Simply start the trainer using our Auto-start system, and spin away. Most users start noticing results after only a couple of days of use. Most of our customers are ableย to completely eliminate their symptoms after consistently using our trainer everyday.

Relieve & Rehabilitate:

Using the Powerball for as little as 4 minutes a day can effectively rehabilitate and prevent RSI, relieve muscle soreness, help with fracture recovery and increase vascularity. This is achieved, by involving not only your muscles during training but also your joints and tendons. The isometric resistance stimulates the entire muscle in an endurance exercise, which allows all stated tissues to work in harmony whilst under load. The endurance exercise will allow you to improve your vascularity by ensuring an increaseย in heart rate and blood circulation. All of this is achieved whilst saving our customers from having to undergo surgery and spending ยฃ1000s on medication or ineffective physiotherapy.ย 

Areas of Improvement:

  1. Wrist Muscles: Our trainer specifically targets the muscles in the wrists, helping to strengthen and condition them. This is beneficial for individuals who perform activities requiring repetitive wrist motions, such as typing on computers, playing musical instruments, or sports like tennis and golf.

  2. Forearm Muscles: As you spin the trainer, it creates resistance that engages the muscles in the forearms. Regular use can help build forearm strength and endurance, which is useful for various activities such as rock climbing, weightlifting, or even everyday tasks that involve gripping and lifting objects.

  3. Grip Strength: The trainer requires a firm grip to control and spin the device. By consistently using it, you can improve grip strength, which can be advantageous in activities like weightlifting, martial arts, and sports such as basketball, baseball, or racquet sports.

  4. Finger Muscles: The spinning motion of the Powerball RSI Trainer engages the muscles in the fingers, promoting strength and dexterity. This can be particularly beneficial for musicians, gamers, and individuals involved in activities that require fine motor skills and finger control.

  5. Upper Arm Muscles: While the Powerball primarily targets the wrist and forearm muscles, the engagement of these muscle groups can indirectly benefit the upper arm muscles, such as the biceps and triceps. This can provide additional toning and conditioning of the upper arm region.

  6. Hand and Wrist Flexibility: Regular use of our RSI trainer can improve flexibility and mobility in the hands and wrists. This can be helpful for individuals recovering from injuries, those with conditions like arthritis, or anyone looking to maintain or enhance their overall hand and wrist flexibility.

Having stated the above, It is important to note that our trainers main goal and advantage, is to provide relief from RSI symptoms, pains and discomfort. This includes pains and discomfort in the areas of the fingers, wrists, forearms, biceps and triceps and even in the shoulder area.

Automatic Start:ย 

Our trainer, comes with an Auto-Start system designed to maximize convenience and practicality. Simply, rotate the ball core in the correct direction and release for an automatic start. This makes our trainer very practical and easy to use on-the-go. It is always ready to spin.

Highย Build Quality:

Our Gyro, constructed from a military-grade plastic shell, ensures to be drop-resistant even in the toughest of scenarios. The stainless-steel rotor axle, keeps the Gyro 100% vibration-free during your endurance exercises. The built-in grip band around the Gyro, ensures to provide maximum grip.

Aside from providing relief from pains of RSIs, our trainer also serves as a perfect warm-up tool for any exercise routine, while at the same time preventing potential injuries and strains related to training. This makes the Gyro, arguably the most important tool in the 'ESSENTIALS' collection.

What the experts say.

Imran Hassan, University of South Wales.

RSI & tendon fatigue research program.

"Whilst studying the RSI trainer, we have noticed its ability to work flawlessly in adapting to many different cases of RSI conditions. We were particularly stunned by the trainer being able to target all common areas of RSI discomfort all whilst using the same type of exercise routine. We can see, that this type of trainer will soon quite possibly remove the need of using physiotherapy services in order to eliminate RSI conditions and symptoms.

To conclude, we sincerely recommend the RSI trainer to anyone who might be struggling with pain and or discomfort, and wants to start self-treating from the comfort of their own home."
