The PFLEXXI Knee Exerciser is a revolutionary product in the field of wearable exercise products. Knee injuries affect a huge number of people, and can really impact you performance in sports, or even your mobility in everyday life. Most braces may give good support and stability to the joint, but they don't have the ability to exercise and strengthen your knee at the same time.

This is where the PFLEXXI stands out from the rest, with built-in resistance in the form of springs that help rehabilitate or even build muscle. These can be interchanged, as the PFLEXXI also comes with various sets of springs of differing resistances, based on your needs.

Who Can Make Gains with the PFLEXXI Knee Exerciser?

The PFLEXXI is a very versatile product and can be worn on the move to build muscle while you carry on with your everyday life, used in training programmes, or to complement a physiotherapy treatment programme. It can be worn at any time, for day-to-day activities or whilst exercising. With a sporty wrap around design, the Knee Exerciser is easy to fit, and comes in a choice of sizes to find the most comfortable fit.

The PFLEXXI comes with three sets of spring resistances, each of which equates to a different load around the knee. A white 3.5 kg resistance comes fitted with the product, but this can be changed to the 5 kg yellow spring set or the 7.5 kg black set. The product is ideal for athletes who want to improve performance and limit recovery times, but is equally suited to people from all age groups and activity levels, due to the various resistance levels and versatile nature of the product.

Please note : It is recommended that you insert springs of the same resistance on either side of the knee.
