Disc flare-up after months of rehab: how to rebuild a lifter’s program after a setback

A disc flare-up after months of rehab is one of the most frustrating setbacks you’ll deal with, and to go along with today’s episode I have a nice infographic to share…

In today’s video we break down a real case: a disc flare-up after months of rehab, and how to rebuild a lifter’s program after the setback:

Your lifter spends 5–6 months rebuilding after a disc injury. Tempo squats, slow progressions, deloads, everything done “right.” They get back to squats and CrossFit… then the leg pain comes back. Now even the warm-up hurts. Do you start the whole program over?

In this live case breakdown, I answer an Insiders Academy member’s question about lumbar radicular pain and rebuilding a training program after a setback. We walk through what went well, what to reassess, and how to find a starting point the athlete can tolerate today. It’s built for physical therapists, rehab professionals and coaches working with lifters and active patients.

What You’ll Learn About Managing a Disc Flare-Up

  • How to reassess work, sleep and daily activities after a flare-up
  • Ways to modify strength training with upright, single-leg and partial-range exercises
  • Where blood flow restriction fits when heavy loading is limited
  • How to progress squats and deadlifts back toward normal training
  • How to adjust reps, tempo, training volume and reps in reserve (RIR)
  • How to set expectations and discuss the next steps with the athlete and coach

Disc Flare-Up Rehab: Key Points From the Research

  • Setbacks are normal, not failure. In 250 people who had just recovered from low back pain, 69% had a recurrence within 12 months and 40% had a recurrence that limited activity. Median time to recurrence was 139 days (da Silva 2019).
  • Recovery is rarely linear. In 609 primary care patients with back-related leg pain, 55% had improved at 12 months. A patient’s belief that the problem will last a long time was one of the strongest predictors of a poor outcome (Konstantinou 2018), so how you frame the flare-up matters.
  • The disc can heal on its own. Spontaneous regression was seen in 96% of sequestrations, 70% of extrusions, 41% of protrusions and 13% of bulges (Chiu 2015). A flare-up doesn’t mean the disc is getting worse.
  • Modify for symptoms, not fear. Across 11 studies, 9 found no significant difference in lumbar flexion during lifting between people with and without low back pain (Saraceni 2020). Reducing flexion early can calm things down, but it isn’t a forever rule.
  • Keep training. A network meta-analysis of 89 trials found resistance training and stabilisation/motor control exercise ranked among the most effective options for improving function in chronic low back pain (Owen 2020).
  • BFR bridges the gap when heavy loads hurt. Low-load blood flow restriction training produced a moderate increase in strength (Hedges’ g = 0.52) and was more effective and tolerable than low-load training alone, though heavy loading still came out ahead when it’s tolerated (Hughes 2017).
  • You don’t need to train to failure. Strength gains were similar across a wide range of reps in reserve (Robinson 2024), and stopping sets at 1–2 RIR produced similar quadriceps growth to training to failure over 8 weeks, with less fatigue (Refalo 2024).

Our goal? Help you rebuild your lifter’s program after a disc flare-up so they get back under the bar with confidence, and stay there.

Stop guessing when your lifter’s back pain flares up.
