The quadriceps are one of the most powerful muscle groups in the body. Used in walking, jumping, squatting, lunging and running, the quads also support knee extension and the patella. (Read more on the STACK Quads page.) You can appreciate why you should stretch your quads before engaging in activity.
I recommend two main quad stretches for athletes: the Standing Quad Stretch and the Lying Quad Stretch. Both quad stretches should both be performed for one or two sets during every stretching routine. Hold each stretch for a slow count of 20 to ensure that the muscle is being thoroughly stretched and to increase its length. Always remember to keep breathing during each stretch.
To add a stretch for the hip flexors and quads, simply tighten your glutes. This should allow you to feel a slight stretch in that area.
