  • The Pflexx® Compression Knee Trainer has patented Power Springs providing functional fitness resistance training. Our Power Springs are fitted on either side of the knee joint and work naturally against physical movement to strengthen the knee joint and build muscle in the quad, hamstring, calf, and glutes.

  • The high compression knee sleeve is made from Advansa Thermo°Cool® textile which keeps you warm when cold and cool when hot. The level of compression helps keep the blood flowing and disperses lactic acid, speeding up recovery time and reducing tiredness.

  • The Pflexx® Compression Knee Trainer can be worn anytime: during day-to-day activities or when exercising.

It can be used to:

  • Strengthen the knee joint prior to surgery.
  • Help rebuild muscle strength after surgery.
  • Boost power and strength for sports performance.
  • Help people suffering from arthritis.
  • Pflexx® Compression Knee Trainer minimises recovery time and maximises training results meaning you can get back to a fitter lifestyle faster. It is ideal for athletes who want to improve performance but limit recovery times.
  • The patented Power Springs come in three resistance levels making sure you have the right resistance.

After 13 years and numerous knee operations, I have lost considerable muscle mass around my knee. The Pflexx Knee Exerciser is a revelation, working my knee to improve muscle mass and stability. Although not officially a support, an added bonus is that I also feel more confident wearing the brace. Huge thanks to John, who has been fantastic answering all my questions and his customer service second to none. Here's to a bright & more active future for me (my husband also has one which he uses for skiing).

Absolutely miraculous product. My husband had a knee injury and couldn't put any weight on it! Within a few days of wearing the Pflexx Knee Exerciser he was back to work with full knee movement.The doctor couldn't believe the recovery in such a short period of time!

Les, thanks a million for the Pflexx Knee Exerciser. Six weeks ago i was in a bad way barely able to walk..... The Pflexx arrived and you saved my leg..... I could literally run a marathon now. What a result, I owe you one! Have a great New Year and continued success with an incredible ingenious product.

The Pflexx Knee Exerciser is really easy to use you just slide it on. Following my knee operation I was lacking confidence and my knee felt unstable but using the PFlexx Knee Exerciser not only felt like it provided support. But also the slight feeling of resistance makes you understand that it's working your knee whilst you carry out everyday activities. My knee feels strong now and I was back playing rugby again within 5 weeks of my meniscus operation.
