I'm sorry but I couldn't disagree more. I'll just relay IronAddict's opinion, as it is the same as mine:
"I could write pages praising the advantages of the Trap Bar and it's value in assisting the trainee to reach their physical potential. This piece of equipment, when used correctly has the ability to transform physiques. Muscles worked when using this movement are thighs, hamstrings, glutes, lower back, upper back (lats, mid back, traps), forearms, and abs/obliques. In other words, the same muscles used a when performing the bent legged deadlift. So what makes the Trap Bar so special, and makes it a superior movement to the strait bar deadlift? Simple, works the same muscles as the conventional deadlift while making it a safer movement by avoiding undue stress to the lower back and providing more stress to the thighs. Because it reduces the need for extreme technical proficiency as required during the strait bar deadlift most trainees are able to push harder and move more weight. The sum total is a super productive movement that works approximately 70% of your lean body mass relatively safely."
