Triangle Pose

This classic yoga pose is great for a stretch after any kind of exercise. It stretches the huge fascia connection that runs throughout the body and usually gets constricted in the midsection.

Step your feet a little wider than shoulder width (or wider if you prefer), arms outstretched to the sides. You can start with either side, but, for the sake of blog-writing purposes, let's start with the left side. Extend your left hand and arm as far straight out over your left foot as you can while also shifting and stretching your upper body to the left BEFORE reaching down for your ankle. Once you've stretched everything from the waist up as far to the left as possible, THEN carefully reach down for your ankle, shin, foot, the ground, or wherever you can with your level of flexibility. Now stretch your right arm straight up to the sky and look up at your right hand. Push your chest forward and get as much upward rotation in your upper body as you can.
To push the stretch a little further, take the right arm over your head, keeping your arm by your right ear. Keep extending your chest upward and outward.

The explanation is a bit wordy, but the stretch is so great!
