※ I previously listed the same product, but it sold, so this time I made the hole to bypass the foot bar adjustment pin 51mm. This allows it to be inserted into a plate rack, increasing storage efficiency. Please refer to the photos. This is a hip thrust block that perfectly fits the TUFFSTUFF/Tough Stuff Power Rack RPR-265. It may also fit the CPR-265 (current model), but I don't have one nearby to test, so I'm unsure if it's usable. You can perform hip thrusts by hooking it onto the foot bar of the high/low pulley and having it touch the weight stack behind you. Compared to simply placing your feet on the floor, the hip flexion is deeper. Even when the barbell hits the safeties, your glutes are slightly lifted off the floor, allowing for maximum range of motion. You can also easily move away from the barbell by placing your glutes on the floor, and easily change the weight. It is designed to bypass the foot bar adjustment pin. As it is custom-designed, it fits perfectly with the foot bar and weight stack. I've seen people do hip thrusts with their feet on the floor, but due to the angle, the quadriceps tend to overwork. (This is why hip thrust machines always have an incline for the foot placement.) By using this, you can more easily stimulate your gluteus maximus with a power rack, similar to a hip thrust machine. Also, depending on the type of bench, if you have a decline bench, even when the barbell hits the safeties, your glutes won't touch the floor, allowing you to safely push to your limits in a position very similar to a Glute Builder (hip thrust rack). (I use a Tough Stuff CMB-375 for this.) Some may find it expensive, but it involves significant material costs and labor. Please refrain from negotiating the price. This is highly recommended for those who do hip thrusts at personal gyms but do not have space for dedicated equipment. *It is set to "near unused" as it has been tested a very small number of times during field testing. If you are looking for something cheaper, please see my other listing. Please refrain from purchasing if you are sensitive or seeking perfection.
