Bars by HULKFIT. Details:Expand your home gym fitness equipment collection with our hex shaped trap bars. Build a solid lower body and workout your legs with deadlift and squat exercise routines. The main benefits of these bars are to engage the gluteus muscles with thigh and calf muscles. Supporting structures like the hamstrings will increase strength and give you more stability. More importantly the user will experience less force and pressure on the spine. Knurled handles are machined micro incisions that allow you to avoid slippage that occur during high intensity workouts. You will develop increased grip strength in the process. Slide bumper plates on these barbells with relative ease and secure your plates using our clamp collars. These bars feature a closed design that helps keep your body in the correct lifting position and has a handle-to-handle space of 23.25 with a loadable sleeve measuring 9.25. The diameter of the sleeve will fit standard 2 plate collars.
