Pull-up device capable of training finger grip force

Abstract

The invention discloses a pull-up device capable of training finger grip force. It is equipped with bracket to fix the left and right climbing components in the air. Meanwhile, the climbing component is equipped with knuckle receiving portion to permit the fingers to hold the knuckle receiving portion for pull-ups. With the setting of the climbing component, we no longer hold the crossbar, but just grip the climbing component by the fingers when we do pull-ups. Thus, the grip force of the knuckle muscles is exercised as well as the arm strength.
