Tight hamstrings and lower backs are common complaints among runners, office workers, and people who are on their feet all day. Doing forward bends regularly can help tremendously, but doing them on your own just isn't as effective as when you can get some help. I've already showed you how to do Seated Butterfly Lunge and Seated Straddle Lounge, so here's another variation to try. The person on the bottom gets an amazing stretch for the backs of their legs, and the person on top feels an incredible lengthening in their spine.

So grab a friend and read more.

• Partner #1 sits on the ground with his legs extended straight out in front of him. He folds forward as far as he can, coming into a Seated Forward Bend.
• Partner #2 gently sits down on Partner #1's sacrum at the base of his spine (aka back of pelvis), and begins to lie down on Partner #1's back. Partner #2 should move slowly because this is a really intense stretch for Partner #2's hamstrings. Partner #2 can stay here (as in the picture shown to the right), or if it feels OK, she can extend her arms overhead and straighten her legs.
• Both partners talk to each other, making small adjustments if necessary. When either partner is ready to get out of the pose, Partner #2 lifts her torso and sits up.
• Then each partner switches roles.
