The Rectus Femoris Muscle is one of the 4 Quadriceps muscles of your leg. I hate to disagree with your exercise regime, but the RFM's function is to flex the thigh at the hip joint and to extend the leg at the knee joint. So this should tell you how to be exercising it. Bicycling it great for this to, according to a PT friend of mine. Best of luck with this nagging injury, let me know if I can give you anymore info! jd1963
Also, I should point out that I am not a doctor.
I am an athletic trainer. As an athletic trainer, one of my main focuses is the prevention, diagnosis and rehabilitation of orthopedic injuries.
