This is a common groin/adductor stretching mistake that is potentially damaging to your medial ligaments and meniscus of the knees.
When you add the little tweak that I show you to this exercise, it not only takes the stress off these tissues but also activates glute and hip external rotator muscles.
Kill 2 birds with 1 stone!
Give it a shot and use this tip whenever you perform this stretch.
You can even add some contract/relax and scouring to the stretch to make it more effective, for more on these advanced techniques, grab the Hip Flexibility Solution program at http://HipFlexibilitySolution.com.
