Rogue Renegade Row Handles not only work well for their namesake movement they can also be used for other row variations as well as weighted bear crawls and even weighted handstand walking. They also make a firm base for pushups allowing you to reach the full range of motion, rather than being stopped when your chest hits the ground.
They have 5.25″ tall posts and bases large enough to fit most 25 pound steel plates. That means that loading them up to 75 pounds will not be an issue.
