that's exactly why i got the trap bar, allows you to concentrate on the weight not your position and posture.
tell me about them.
It's essentially a partial deadlift in a power cage...
Place the pins in the cage so that when the bar is resting on it it's located just barely above your knee. Perform the deadlift with the same form as the traditional one from the floor. This adaptation allows you to use significantly more weight while taking your thighs out of the movement to a great degree. Your mid-upper back is getting a large amount of increased training load. You should not only notice increased trap development but a significant increase in overall back thickness (paraspinals, rhomboids, etc).
