Easy stretch for lower back and legs...
If you get lower back tension, or, would just like a really nice stretch...you may like this. (This is a good one if you sit a lot or work at a desk).
All you need to do is lie down on the floor, or your bed, and bring your legs up against the wall.
You may want to add a towel or pillow under your lower back to support it if you're doing this on the floor.
You'll feel a great stretch going down the back of your legs and lower back.
Hold it for 10 mins or so - whatever feels comfortable for you.
Let us know how you feel after this one!
