Regular use of our Helix Tricep Bar will grow your arms until it seems that strength and definition were in your DNA all along. Its sleeves--those ends of the dumbbell that hold the weight--rotate independently to give you maximum mobility and uniform stability, and their 1-inch thickness allows you to attach most standard plates to the Helix. Triceps aren’t the only muscle you can train with the Helix. Do hammer curls with the inside grips to target the interior of your bicep or grip the outside bar for standing rows. The small-diameter diamond knurling increases the surface area of your grip so you can lift more weight with minimal damage to your hands or gloves. Besides all its sterling functionality, the Tricep’s chrome finish looks great and is a credit to any barbell collection.Specifications:Length: 37 InchesWidth: 8 InchesHeight: 4 InchesWeight: 27 Lb
