I recently tried rack pulls, in the hope of using 20kg (44lb) more than my current max in terms of weight. The goal was to use this for some reps, slowly working the bar down the rack until it's touching the ground. This would give me a new max of 4 plates or 180kg, work out the rest if it's important.
However, I was training with my friend who's shorter than me by about 15cm (5-6")
This meant that the rack was set for his Vastus Medialis height and one pin too low for me.
In short, I couldn't lift any more weight using rack pulls. Very disappointed, I was looking forward to playing with some bigger weights than before.
I don't believe this could be because it was one pin too low, is there anything else that may be an issue/has anyone else had this happen to them?
