The COREFX Pro Loops are resistance bands that can help you reach your fitness goals, helping you with stretching, toning, and strengthen specific areas. The Pro Loops can be added to a wide range of exercises to turn up the dial on your workout. Take them to the gym, use them at home or bring them with you when you travel so that you can always give yourself the challenge you need. Our loops are made with the highest quality, 100% natural latex, with a smooth outer texture to stay in place. The smooth finish also prevents our bands from pulling at your hair or skin, ensuring you have the most comfortable workout possible!
