What is the best stretching exercise i can do?

If you need back stretching do cat stretch/kid pose and you can also do the seal stretch. Another great one is stretching your wrists. And my favorite are straddle and Pike.

Some of my favorite stretches to do are:
Touching my toes
Tree pose
Cat/cow pose
Reaching behind my back(as far as you can go)
And finally rotating my neck from side to side

i like to flail my arms around, if you know what i mean. after doing this my shoulders feel very relaxed and free. i also like to stretch out my spine by bending my self "in half". my back feels great after this.
