These stretchy exercise bands are latex-free, have powder-free easy-to-grip surfaces and are preferred over other latex-based bands. Each band is color-coded by resistance level for your convenience – the darker the color, the more resistant the material is and difficult to stretch. It is also puncture-resistant, tear-resistant, and burst-resistant. Stretch, tone and condition your muscles by either holding it in your hand, mounting it to a wall, or looping it in a knot. These single packs contain 5-foot ready-to-use exercise bands. Great for developing core strength and gross motor skills as well.
