What a great piece of equipment this is. I was looking for a bar to make doing upright rows and lying tricep extentions easier on my wrists. If you use a standard straight bar, it tries to pull your wrists at all sorts of angles, especially on upright rows. Using this one, the angle of the bar is exactly where your hands need to be. Also the U-shaped bit in the middle goes under your chin, so you don't hit yourself with it, like I was, using a straight one.
The price is very good too. Your talking about £40 for kit like this. Amazon was the cheapest by far. I would recommend buying this bar just for doing upright rows as it has improved my form by 50%.
