It's not an absurd statement. Deadlifts improve so much musculature in your body which resolves/prevents injury. I had a 3+ year long knee injury from running and the only remedy was heavy squats. I was considering surgery and experimental stem cell injections since nothing was working. Thankfully I tried strength training before the alternatives.

It's important that people understand proper deadlift form though. It's a bit more complicated than just picking the barbell up off the ground.

I think it might appear that way to anyone who doesn't lift, but OP is not too far from the truth.

I'd say the same for barbell squats. You don't want to be 45 and not be able to get off the toilet without holding onto something...

Why? Deadlift is absolutely magic for back pain. You don't even need to lift 'heavy', just regularly.

How so? When done properly they are great for lower body and back strength.
