WHAT DOES THIS BAR DO THAT DUMBBELLS DONT? In push workouts such as the Bench and Shoulder Press, the Sliding Grip Bar intensely resists bringing the handles closer (converging), and also resists taking the handles far out in pull workouts such as in rows and upright rows. This results in a totally next level contraction and pump, making your workouts more effective in a lesser amount of time, and delivering noticeable growth. This resistance increases with an increase in weight, and is felt more at the later parts of the working set. With sliding grip bars, there is more stability than dumbbells due to synchronized handle movement. The Sliding Grip Barbell is a one-of-a-kind bar with built in handles that move along the shaft length. This design gives you the freedom of movement like dumbbells, but with the control of a barbell. It combines the best of both, offering a stable and effective way to target your chest, shoulders, arms, and back. Sliding Grip Bars also provide a unique style of resistance, delivering a very unique training experience, contraction, and pump similar to that of a high-end gym machine. Sliding Grip Bars quickly exhaust muscles and allow for complete isolation of the targeted muscle. Bench Pressing with this bar significantly reduces the involvement of triceps and shoulders, allowing your chest to do most of the work. During the positive "push" movement, you'll experience converging resistance as you bring the grips together, enhancing the effectiveness of your workout. The converging resistance increases with the increase in weight and is felt more in the later parts of sets.
