The active quadriceps stretch is an effective warm up exercise for the knee by taking it through the full range of motion.

  • Stand with feet shoulder width apart. 
  • Keep the hips and abdominals tight so that as you raise your right lower leg, the upper leg stays in line with the left leg (doesn’t move forward or back). 
  • Return to the starting position and alternate legs for a total of 10 repetitions (5 per leg).
