Before I start, let's not turn this topic into further debate as to whether weight-work helps or hinders cycling. What I want is specific advice about a specific exercise if anyone has any thoughts.
I just started doing some deadlifts with the aim of strengthening my lower back. I don't aim to go really heavy but to use moderate weights. However, I'm not sure whether to continue doing them since I've always felt uncomfortable with the exercise. The quotation I just found explains why:
"Because the leverage on them (deadlifts) is mechanically all wrong. Even when you know the proper technique, it doesn't matter. It still throws your lower back out. Sure, deadlifts can make you stronger - but not in the long run. In the long run they cripple you."
After reading that I now think I know what my problem is and the above hits the nail on the head. When I attempt to deadlift, I hold my head up, looking straight ahead, grab the bar, bend the knees a little and lift the bar to my waist. But the problem is that when you bypass the knees, surely you have to deviate from the course? The only way you can deadlift with a totally straight back would be if the knees don't get in the way?
I feel there must be some kind of slight curve in my lower back when deadlifting past the knees, so is this fatal? And how much knee bend should you use?
The reason I ask is I've had back aches over the last few months and figured deadlifts might strengthen my lower back. But maybe I should use hyper-extensions instead?
