Intermittent Lower Back “Power Loss” During Deadlifts — Seeking Advice

Hi BBM Team,

I’ve been experiencing a recurring, unusual sensation in my lower back that intermittently affects my deadlift and squat performance — and occasionally even day-to-day tasks like picking up objects or putting socks on.

History of the Issue:
The first instance occurred around November last year while deadlifting. I can’t recall the exact BBM program I was running, but I was working through multiple sets at prescribed rep ranges when, mid-rep, I felt what I’d describe as a sudden “power loss” in my lower back. It wasn’t exactly painful, but I immediately felt unable to finish the rep — like the strength had drained from that area. Performed some air deadlifts and air squats and continued rest of the session - nil issue.
I then went on a month-long Europe trip with no training, and after returning, the issue seemed to vanish. Training was fine and if anything I was on a really good trajectory. I ran some general BBM templates and I recently started running the old school Strength 1 template for about two or so cycles with Sumo as main and conventional as the supplemental. I was on my way back to my previous strength standards before I started shift work which was super exciting.

However, two weeks ago, the same sensation returned — this time during a back-off set. My top single@8 and 5@9 set felt fine, zero issues, but during one of the 76% back-off sets, I experienced the exact same “power loss.” It also happened during the sumo deadlift a few sessions after, although I was able to push through without it recurring during the session.

Yesterday, I approached conventional deadlifts cautiously due to some anxiety about this sensation. I purposely undershot my single by ~25kg. However, as I initiated the pull, I felt that same power loss again. This time it was accompanied by tightness and mild pain. I performed some air deadlifts and squats to loosen up, and by the third set my ROM and comfort returned. I finished the session (press and split squats) with no further issue.

This doesn’t feel muscular — it feels deeper, possibly spinal, but again, I’m not experiencing constant pain or limited ROM. The issue is inconsistent and only pops up during certain hinge or bend patterns, like a momentary “jolt” of instability or power outage that resolves shortly after. I will occasionally experience it in day to day life after it happens - i.e. putting socks on, bending over to pick up laundry etc.

What could this be, in your experience?
Is it worth taking a break from strength-focused templates and moving to something like your Hypertrophy template with more variation and altered loading parameters?
Do you have any general advice on next steps, whether rehab or programming-wise?

I know the old Aussie “she’ll be right” attitude isn’t ideal here, and I want to be proactive so I don’t push myself into a real injury. Any guidance would be appreciated.

It is just kind of annoying that it is not predictable so I’m finding it really hard to map out what an appropriate entry point would be.

Thanks guys,

Lachy,

Thanks for the post.

No specific diagnosis immediately comes to mind based on the stories here. More importantly, it doesn’t sound like this will require a special technique for management.

Whether or not you need to shift from strength-focused programs to something else when you’re back to unrestricted training is up to you. Right now, I do think some dedicated low back pain “rehab” would be a good idea to reduce the sensitivity you’re experiencing and build your tolerance for loading up a bit. We lay this out in our articles here and here, as well as the low back pain template.

If this happens again, you may benefit from a consultation with one of our pain and rehab specialists. Please reach out to us via support@barbellmedicine.com.

Hey Jordan,

Thanks for taking the time to read all that. I think the external validation is what I needed to stop myself from overthinking it, although I haven’t really been overly stressed out by it. Typing that post out was just a good way to put into words what I was experiencing.

I think I will switch to the hypertrophy template as it will just encourage me to not want to follow my primitive drive of trying to chase heavier singles or triples each week haha.

If I have future issues I’ll definitely consider a consult.

Thanks again!
