Using resistance bands is easy. Users need to step into the interior of the band for it to stretch around the legs. From here, the band can be used to add tension to a range of exercises, such as lateral leg extensions. For squats, resistance bands are used to maintain the feet at a certain distance from one another through movement. Resistance bands are also used for most mobility drills. Hip extensions are often performed with bands before moving on to weights to warm up the muscles.
