Secure the band around a stable post, such as a table leg, chair leg, etc. The band should be a circle (meaning the ends of the band should be secured together). Step into the band with your affected leg and pull the band up so it rests behind your bent, affected knee. Be sure the knee is bent. Stand up straight and extend, or straighten, your knee. Focus on using your quadriceps muscles. Step back from the stable post to increase the resistance. The goal is to perform at least 10 times. If you can perform more than 15 easily, then step back further and/or change the band to increase resistance.
