This product is the only one available. It is also listed elsewhere. Thank you for your understanding. (Compared to simply placing your feet on the floor, this allows for deeper hip flexion. Even when the barbell is resting on the safety bars, your glutes will still be slightly off the floor, allowing you to maximize your range of motion. You'll also find it easy to move away from the barbell and change the weight.) This is a hip thrust block that perfectly fits the TUFFSTUFF power rack RPR-265. It may also fit the CPR-265 (current model), but I'm not sure as I don't have one nearby... You can perform hip thrusts by hooking it onto the foot bar of the high-low pulley and positioning it against the weight stack at the back. It's designed to clear the foot bar adjustment pins. Because it's specifically designed, it fits perfectly, with tolerances of less than 1mm, for the foot bar, weight stack area, and adjustment pin area. I've seen people do hip thrusts with their feet on the floor, but the angle causes the quadriceps to be overused. (That's why hip thrust machines always have an incline where you place your feet.) By using this, you can stimulate your glutes in a similar way to a hip thrust machine, using your power rack. Also, depending on the type of bench, if it can be declined, even if the bar hits the safety bars, your glutes won't touch the floor, allowing you to safely push yourself to the limit in almost the same position as a glute builder (hip thrust rack) (I use it with a TuffStuff CMB-375). This is highly recommended for those who do hip thrusts at personal gyms, etc., but don't have space for dedicated equipment. This is a newly manufactured item, but I am also selling a used one that I made myself. *I've only tested it a few times during location testing, so it's listed as "like new." If you want the cheapest option, please take a look at that one. Shipping will be via Yu-Pack size 100 or 120. Please refrain from purchasing if you are overly sensitive or seek perfection.
