The key thing that he calls out in this and other videos is that most people do not have sufficient hamstring flexibility to safely deadlift off the ground (lack of flexibility will force your back out of a neutral position "rounding of the lower back"). There is certainly no shame in starting your deadlift from an elevated position by stacking plates underneath the barbell or pulling off rack pins while you work long-term on improving flexibility.
I highly recommend watching any of his videos before attempting any exercise, even ones that you think you know how to do well, e.g., bench press :)
It's incredibly counterintuitive. Everyone's assumption, if they don't lift weights themselves, is that my case is some kind of weird exception or coincidence, and I can't really blame them. I have no idea how to explain that there's a good chance that they are misusing their back, and that they would be more comfortable sitting, standing, walking around, and lying down if they strengthened the muscles in their back. First of all, why in the world would we need to learn how to use our own bodies as adults; don't we figure this out as toddlers? And second of all, if we spend hours every day sitting down, hours every night lying down, and maybe hours every day walking around and jogging, why in the world would our backs not be strong enough to do those things safely and comfortably? Isn't doing something for hours at a time exactly the right signal to prepare your body for doing that thing?
But it seems to be a very common experience for people who try lifting weights: they find that they are much more comfortable sitting at their desk at work and lying down in their bed at home if they lift heavy things on their feet at the gym. I wish I knew how to convince people to try it.
I am over 2m00 high.
If this sounds "cool/lucky" for most people. It is in reality a nightmare if you are office worker. Everything is in your environment generally lower, shorter or inappropriate for you... This trigger improper posture and inevitable backpain.... Chronic backpain in my case.
After passing through everything, including painkiller, osteopathy, chiropractic, surgery (back bone injection) without any better results I tried (pure amator) weight lifting and this was a miracle for me.
My situation get much better, in just a matter of few months.
My 2 cents on that is weight lifting force you to fix your posture and imbalance when you practice it. Muscles have Memory, and this, even if it is counterintuitive, help a lot.
It was the day after a hard 20 mile run, and I stupidly tried to deadlift my 1 rep max in that fatigued state. Something popped and I felt a sharp pain in my lower back. It hurt really badly for about 3 days, and made it difficult to put on socks and pants. And then it healed right up. No pain ever since, and I went right back to deadlifting.
I'm saying this as someone who loves the dead lift and picking up heavy things.
Form is critical too, so with every single lift that you do, make sure you're using the correct form first, otherwise you're potentially wasting your time and putting yourself at risk of injury.
So.. don't assume that your results are predictive of the results for everyone (typical mind fallacy/typical body fallacy?)
But doing a deadlift properly is the most natural type of movement.
Like lifting your child off the ground. Or putting a sandbag in the back of the truck. I've done thousands and thousands deadlifts with no injury.
Can you provide a reference for your assertion?
Notice how this doesn't apply to jumping jacks or the plank.
That you always have to couch the benefits of deadlifts in the "when done properly" disclaimer should be a hint as to what they're talking about. Hell, even lifting with one's legs instead of one's back comes so unnaturally to some that my refrigerator's box came with "lift with legs" instructions stamped onto it complete with a series of pictograms.
As to whether the deadlift in fact has a high risk of injury, it would seem he agrees with you (and myself, for what that's worth): not really.
I've had back pain for about 2 years, up until recently. I did weekly physiotherapy for an extended amount of time until my doctor recommended neurodynamic exercises. It's basically focusing on stretching your nerves. I did that daily for 6 weeks and my pain was mostly gone. When I feel it's coming back, I do the exercise maybe once a week and I'm good. On top of that I can now focus on improving core strength. It's a huge motivator knowing how bad it feels, but that you have it under control (which was a huuuge relief).
Edit: my back pain was caused by bad posture, which was caused by pain from an untreated slightly ruptured intervertebral disc.
