The Rotating Pressdown V-Bar is a precision designed cable pulley attachment for use with a range of bicep and triceps movements. ... The bar angle is designed to maximally stimulate the triceps on pushdowns and when flipped, the biceps when performing cable curls.
This press down v-bar is perfectly balanced to provide a smooth exercise execution. The swivel feature allows you to get that extra twist at the bottom of the pushdown movement and the top of the curl action, to fully engage the working muscle.
