Strong and Safe! The Maximum Fitness Gear (TM) Double Strand Resistance Band is a new, revolutionary, patented exercise band. Its dual latex tubing design is built for maximum durability and better elasticity. The innovative dual latex tubing design is reinforced throughout the length of the band with multiple "elastic clamps", that absorb and distribute band pressure during usage. As a result, the band will not break nor snap like most SINGLE TUBE resistance bands. Use this new state-of-the-art resistance band to develop and sculpt your upper body (chest, back, shoulders, arms) and lower body (glutes, legs). You will experience the most challenging workouts with the Double Strand Resistance Bands. A BONUS Total Body Workout Guide with a sample workout routine lays out what type of exercise you need to do. Use the door anchor (provided) for a variety of workouts that you would normally do at the gym. The Maximum Fitness Gear (TM) Double Strand Resistance Band is guaranteed to outperform leading brands of single tube resistance bands in its class. This product is excellent to use with any popular DVD workout program!
