Are deadlifts bad for your back?
By Mert Yerekapan · Updated
No, deadlifts aren't bad for your back. Done with decent form and a weight you can control, they strengthen the muscles that protect your spine, and strength training in general is one of the things people with back trouble are often told to do. Deadlifts go wrong when the weight is too heavy, the form falls apart, or someone jumps in with no build-up.
What actually causes the problem
Most deadlift back tweaks come from the same few things:
- Adding weight faster than your body adapts
- Rounding the lower back hard under a heavy load
- Yanking the bar off the floor instead of pulling the slack out first
- Doing max attempts when tired or after poor sleep
None of those are the deadlift itself. They're how it's done.
A little rounding is not a disaster
People get scared of any bend in the spine. A tiny amount of upper back rounding is common and fine for many lifters. What I'd avoid is your lower back folding under a weight that's near your limit. If your form breaks on the last rep of a set, the set was too heavy or too long.
How to start safely
- Learn the movement with a light barbell or kettlebell first.
- Set up with the bar over mid-foot, hips above the knees, chest up.
- Brace like you're about to take a punch, then push the floor away.
- Keep the bar close to your legs the whole way.
- Add weight in small steps, and stop a rep or two before form slips.
If the conventional deadlift bothers you, a Romanian deadlift or a trap bar version is a reasonable alternative.

When to see someone
Normal muscle soreness the next day is fine. Pain that shoots down a leg, numbness, tingling, or back pain that doesn't ease within a few days is a reason to see a doctor or physical therapist before pulling again. If you already have a diagnosed back condition, ask them what's safe for you.
