According to the ACFT (Army Combat Fitness Test), a hex bar is utilized to assess a soldier’s upper-body pulling strength, core stability, and overall endurance and conditioning, and a soldier must deadlift 340 lb total to get 100 points to the max. The reason for this choice is obvious: a trap bar isn’t so demanding to the deadlift technique and fits more beginners. Since they need to perform a 3-repetition maximum deadlift, a hex bar is the best option in this case because it doesn’t affect badly the back muscles and spinal cord generally. So, it mitigates and lowers the possibility of serious injuries while pulling heavy plates.
