To complete this stretch, take a knee in front of a wall so that the toes of the leg you have raised are pressing against the wall. Place that same hand against the wall. Reach behind you with your other hand and grab your leg that’s sitting on the floor by the ankle, and bend it back towards your body. Hold this position and lunge forward towards the wall to complete the stretch. Hold this stretch for 10 seconds, then repeat on the other side of your body.
How to do it: Stand up tall while holding onto a sturdy object like a chair, or rest your hands on a wall. Keeping your back straight and core tight, raise one leg up and lift it out to the side and away from your body, keeping your leg straight. Pause for one to two seconds, then return to the start position. That’s one rep. Repeat this movement, alternating sides each time.
Grade II (moderate): A larger tear in your muscle that makes it difficult to move and causes a moderate amount of pain, especially when you move the affected muscle, swelling, and tenderness. You may have 5 percent to 50 percent loss of function and you may be limping. You can't go back to sporting activities until the tear is completely healed. These injuries can take anywhere from a couple weeks to a few months to heal, depending on how bad they are.
