This band is perfect for those who want to build muscle. I have been using these since April 2012 for Power 90 sculpt dvds. I must say while they are perfect and do everything you would like them to do. The design of the handle is far from perfect. The connector piece on the band digs into your skin very much and has often times caused bruising. So much that i now wear gloves when using them. The braided effect gives it more resistance but when doing an exercise that requires the band to come in contact with the skin it can contract and pinch your skin. This results inn me using these bans with either long sleeves and/or gloves.That why it will not get 5 stars because in all honesty, it can hurt you. LOL. Just saying USER BEWARE AND BE CAREFUL.
