Get on a knee and place the other leg out in front of you. Your front leg should create a 90-degree angle.
Have good posture, and shift your upper body forward.
As you shift your upper body forward, you should begin to feel a good stretch in the hip and groin of the leg that is kneeling.
Shift forward and hold for 30 seconds before doing another set or switching legs.
While doing this exercise, you do not have to keep your body completely upright. That may cause you to arch your lower back due to the position of the lower body and the shifting forward. Leaning your upper body forward will most likely be more comfortable and safer.
