This power rack also comes with a 1.25" skinny pull-up bar for higher reps, a 2" fat pull-up bar to work your grip strength, and two reinforced J-Hooks for easy racking and un-racking. Take your workouts even further and add more variety with our power rack accessories like: Pin and Pipe Safeties, Spotter Arms, Roller J-Hooks, and more.
