Designed specifically to reduce bouncing and recoil when released or dropped onto platforms and hard surfaces during high impact exercises such as deadlifts, squats, and overhead presses. The reinforced centre sleeve, that is characteristic of all HIT Fitness bumper plates, allows plates to slide onto barbells with ease whilst also providing protection to the centre of the plate from repeated impact. The Diameter of the plates has been rigorously tested so that the barbell is positioned at the most optimal height off of the ground in order to perform exercises in the most comfortable and biomechanically safe positions. The diameter of all HIT Fitness bumper plates is uniform regardless of the weight.
