We've seen these bands primarily used for pullup and ring dip assistance.  

But what some folks might not know is that they are very useful for stretching.  Loop them around your pullup bar and use them to help stretch out your shoulders, back and chest.

For those that can't quite reach their toes when performing a seated stretch, loop the band around your heels and use it to assist in stretching out the hamstrings and calf muscles.

These 41" bands can also be used in partner resisted running.  Wrap the band around your partner's waist and hold the free ends with both hands.  If you thought hill sprints were hard work...try a set of 10 of these...lung burner time.
