Here is one simple hip flexor stretch which you can do to improve your hip and knee ranges of movement. It is important that you do not bend your knee further than is comfortable. Also try not to arch your back, but rather tighten your tummy muscles and try to gently push your pubic bone downwards into the mat, in order to stretch the hip flexors more effectively.
