I'm doing the straight legged good morning. Am I supposed to fully lock out my knees? Because that seems to hurt at the back of the knee. I tried it a couple of times. Now I just keep my legs straight without locking out the knees completely.
Also, the bar keeps rolling off my traps. I'm using 30kg on the bar, so I prefer not to use the pad on the bar. But when I bend over, the bar keeps moving on my back. NOT a pleasant feeling.
So should I use the pad? Or is there some trick?
