This resistance stretch band is special for two reasons. One: multiple handholds let you decide how deep of a stretch you want. And two: a medium-resistance stretchiness lets you use it to resistance-train, too. Gaiam's Stretch Strap & restore straps are also lightweight and portable so you can strengthen and stretch your muscles anywhere.
