Purpose: General conditioning for the legs with minimal joint impact Start Position: When sitting on the bike seat with the pedal crank in the 6:00 position (down), the knee should be bent approximately 15 degrees. Action: Rotate legs around pedals Parameters: Start with minimal resistance for 8-10 minutes and increase as strength, endurance and joint tolerance improves Tips: If the angle is greater than 15 degrees, raise the seat. If the angle is less than 15 degrees, lower the seat. If the range of motion of the knee is insufficient to allow a smooth revolution on the exercise bike then this may not be an appropriate activity
