HIGH-QUALITY BUNGEE-TYPE RESISTANCE BANDS – Our SportCord Resistance Workout Bands are made of bungee-type resistance cords that are built tougher to last longer, especially when compared to latex resistance bands. Our exercise band set eliminates the need for high-impact fitness systems, such as dumbbells and free weights, and provides a workout option that uses stable resistance to improve strength and endurance. 7-PIECE BUNGEE CORD FITNESS SYSTEM FOR HOME, OFFICE & TRAVEL – Our 7-piece Resistance Band set includes: 3 low-impact exercise bands – light (6-12 lbs. resistance), medium (9-18 lbs.) & heavy (14-28 lbs.) – pair of deluxe handles, wide adjustable strap and door anchor, plus an exercise guide and carrying case! Each cord has a durable nylon jacket – that helps prevent sudden breakage – and steel snap links and D-rings that provide a strong, secure connection. THREE LEVELS OF RESISTANCE FOR PHYSICAL THERAPY, INJURY RECOVERY & MUSCLE STRENGTHENING – Our SportCord resistance cords are 6 feet in length and have three levels of resistance – light, medium and heavy – and are perfect for people of all fitness levels. Each elastic fitness band provides consistent resistance to aid muscle growth and development, as well as support physical therapy exercises to enhance injury recovery and overall strengthening.
