The A300 Squat Pro has all the features of our standard A300 Squat plus we’ve added a movable stop to make it easier to enter and exit the machine. We’ve also enhanced the frame and added 200 extra pounds of weight in the base to help hold it in place. The A300 Squat is our most popular piece in the world of sport. It’s made the athletes who train on it stronger, faster, and more powerful. So, we needed to build them a Squat that would perform under the demands of their body mass and explosive power.
