Pilates resistance band - strong, blue

Most exercises performed with the resistance band simulate training with the reformer. The reformer has been developed by Joseph Pilates and can be found in every big pilates studio. Compared to exercises done on the ground the reformer helps building up muscles and enduringness much faster. The band makes for a similar effect for it offers resistance and thus demands more muscular effort. Using the band is also very recommendable if you strive to invigorate or stretch a particular part of muscles.
