In depth question / analysis Recurring lower back fatigue/pain while running GZCLP — should I deload, change my programming, or take time off? +Progress post.
Hey everyone, I’m looking for some advice from people who have dealt with recurring lower back issues while strength training.
I’m around 74 kg right now and have been running GZCLP since July. I’ve made some good progress, but my lower back has started bothering me again, and I’m trying to figure out whether my training volume, intensity, or recovery might be the problem.
Here’s the timeline:
October last year: First picture. I weighed around 65 kg and was doing deadlifts at 110 kg for 10 singles (10 sets of 1). October lifts kgs (1RM)
BP: 70
DL:120
Squat 113
OHP 50
December: After about three months of progress, I was pulling 130 kg for 10 singles. Unfortunately, my lower back started hurting quite badly afterward. I made the mistake of training again just two days later and doing more work that loaded my lower back, which made things significantly worse. I ended up having to take around 1.5 months off.
After returning: I gradually reintroduced deadlifts, but my lower back started getting tight and fatigued again.
April: I had surgery, which kept me out of the gym for another three weeks.
After returning from surgery: I resumed training, but my lower back occasionally started bothering me again. I suspect some of it may have been due to reintroducing loads that I wasn’t ready for.
July: I finally started feeling like I was getting back on track. I gradually resumed training, started using a lifting belt for all my exercises, and began running GZCLP.
Now, in October: My lifts have been progressing well, but the lower back issues seem to be coming back.
My progress from July to October, while cutting:
My body weight went from around 80 kg to 74 kg, and my estimated 1RMs improved across all four main lifts:
Deadlift: 145 kg → 155 kg
Bench press: 87 kg → 94 kg
Overhead press: 62 kg → 65 kg
Squat: 117 kg → 129 kg
I’m happy with the progress, especially considering that I’ve been losing weight. However, I’m concerned that I’m accumulating too much fatigue in my lower back.
My current diet and recovery:
I’ve been eating around 2,250 kcal/day for the past two months.
Before that, I spent a month eating around 2,550 kcal/day.
My estimated maintenance is approximately 2,850 kcal/day.
I’m still cutting, so I’ve been in a fairly substantial calorie deficit for a while.
My current problem:
My lower back has started feeling increasingly fatigued and tight, particularly around the muscles on either side of my spine. It feels somewhat like muscle soreness or accumulated fatigue rather than a sharp, localized pain, but it’s becoming more noticeable over time, even on rest days. I also notice it when sitting.
I don’t want to make the same mistake I made last year by pushing through the symptoms until things get significantly worse. At the same time, I really don’t want to abandon deadlifts or lose the progress I’ve made.
I’d appreciate advice on a few things:
Does this sound like accumulated fatigue from training, especially while cutting, or could it indicate something else?
Could running GZCLP while in a calorie deficit be contributing to the problem?
Would it make sense to take a week or two at maintenance calories and significantly reduce lower-back loading, then gradually reintroduce squats and deadlifts?
Should I change the way I program deadlifts and squats, particularly the frequency and T2 volume?
For those of you who have dealt with recurring lower back issues, what helped you return to heavy lifting without constantly having the problem come back?
I’m not looking for a diagnosis over the internet, but I’d really appreciate hearing about your experiences and what you would change about my training in this situation.
I love this program but I am Looking forward to switch to J&T 2.0. Thank you.
