Final answer:
A regulation hex bar weighs 60 pounds when unloaded, with a tolerance of +/- 2 pounds.
Step-by-step explanation:
Regulation hex bars, also known as trap bars, are commonly used in weightlifting and strength training exercises.
The specified weight for a regulation hex bar is typically 60 pounds when unloaded. However, there is a tolerance of +/- 2 pounds, meaning a regulation hex bar can weigh between 58 and 62 pounds.
This weight specification ensures consistency and fairness in weightlifting competitions and training routines.
