If you are looking to change up your workout routine for some variety, the SPRI resistance band set kit is a great addition to your home workout equipment and can be used at the gym, at home in your room of choice, traveling, or wherever it is most convenient. The SPRI resistance tube kit features an interchangeable system with 5 resistance bands in varying resistance levels to customize your workout to help meet your fitness goals - ideal for toning the upper body and focusing your core. This versatile and portable kit with door tubes allows for the same exercises you would normally do with pulley-type exercise machines by simulating them in your room of choice whether at home or in gym classes. The secure carabiner clip opens and closes with the metal clasps for an easy on-off to change between tubing and accessories whether attaching to the door, using the ankle straps, or utilizing the padded handles. The kit features a nylon drawstring closure carrying bag to hold all the resistance tubes and accessories - great for travel use in the hotel room so you don't have to miss a workout. You will receive 5 resistance exercise bands, the door anchor, foam handles, an ankle strap, an exercise chart, and a carrying bag for taking all accessories on-the-go.
