A lumbar stress fracture can be one of the most frustrating injuries for athletes. It often forces time away from sport, limits training, and raises concerns about losing strength and conditioning during recovery.
However, while some movements must be avoided during rehabilitation, many exercises can still be performed safely.
The key is selecting exercises that protect the healing spine while maintaining strength, mobility, and trunk control.
This article outlines the best exercises commonly used during the non-axial loading phase of lumbar stress fracture rehabilitation.
Understanding Lumbar Stress Fractures
Lumbar stress fractures most commonly occur in the pars interarticularis, a region of the vertebra that experiences significant stress during repeated spinal extension and rotation.
These injuries are particularly common in sports such as:
Football
Cricket (fast bowlers)
Gymnastics
Tennis
Athletics
Diving
During rehabilitation, clinicians often recommend avoiding axial loading, which refers to compressive forces placed directly through the spine.
Examples of axial loading include:
Back squats
Front squats
Heavy deadlifts
Barbell lunges
Overhead barbell lifts
Instead, rehabilitation focuses on exercises that maintain strength without placing excessive compressive stress on the lumbar spine.
1. Sled Pushes
Sled pushes are one of the most valuable exercises during lumbar stress fracture rehabilitation.
They allow athletes to generate high levels of lower-body force while keeping the spine in a relatively neutral and supported position.
Benefits
Minimal spinal compression
Strong lower body stimulus
Maintains work capacity
Easily adjustable load
For many athletes, sled work becomes a primary lower-body strength exercise during the non-axial loading phase.
2. Split Squats
Unilateral leg exercises allow athletes to maintain lower body strength without heavy spinal loading.
Split squats are particularly useful because they challenge:
Quadriceps strength
Glute strength
Pelvic control
Balance
Loading can be introduced gradually using dumbbells or goblet loading, which typically produces less spinal compression than barbell loading.
3. Goblet Squats
Goblet squats are a common regression from barbell squatting patterns.
By holding the load in front of the body rather than on the spine, goblet squats reduce spinal compression while still training the squat pattern.
They also help reinforce:
Upright torso position
Hip mobility
Core engagement
This makes them an excellent option during early strength rebuilding phases.
4. Single-Leg Romanian Deadlifts
Posterior chain strength is critical for athletes, and it should not be neglected during rehabilitation.
Single-leg Romanian deadlifts help maintain strength in:
Glutes
Hamstrings
Hip stabilisers
Because the exercise is typically loaded with dumbbells or cables, spinal loading is significantly reduced compared with traditional barbell deadlifts.
5. Hip Mobility Drills
Limited hip mobility can increase stress on the lumbar spine.
When the hips cannot move effectively, the spine often compensates during activities such as running, lifting, or rotating.
Common mobility drills include:
90-90 hip rotations
Hip internal rotation mobility drills
Controlled hip extension drills
Improving hip mobility helps redistribute movement away from the injured spinal segment.
6. Thoracic Spine Mobility
The thoracic spine plays a major role in rotation and extension during athletic movement.
If thoracic mobility is restricted, the lumbar spine may compensate by moving excessively.
Thoracic mobility exercises commonly include:
Thoracic rotation drills
Quadruped rotations
Half-kneeling windmills
These exercises help restore normal movement distribution across the spine.
7. Anti-Rotation Core Exercises
During rehabilitation, trunk training typically focuses on stability rather than spinal flexion exercises.
Anti-rotation exercises are particularly effective because they train the trunk to resist unwanted movement.
Examples include:
Cable chops and lifts
Pallof presses
Split stance anti-rotation holds
These exercises develop pillar strength, which is essential for protecting the spine during sport.
8. Single-Leg Stability Exercises
Single-leg control is critical for athletes returning to running and field sports.
Exercises that develop single-leg stability include:
Supported single-leg balance
Single-leg stance with trunk control
Split stance control drills
These exercises improve coordination between the hips, trunk, and lower limbs.
Training Principles During Lumbar Stress Fracture Rehabilitation
While selecting the right exercises is important, how the exercises are programmed is equally important.
Key principles include:
Avoid Axial Loading
Exercises that place significant compressive load through the spine should generally be avoided during early rehabilitation phases.
Prioritise Movement Quality
Exercises should be performed with controlled movement and neutral spinal alignment.
Maintain Strength Where Possible
Completely removing strength training often leads to rapid deconditioning.
Instead, strength should be maintained using alternative loading strategies.
Address Mobility Restrictions
Improving mobility in the hips and thoracic spine can reduce stress on the lumbar spine.
A Structured Lumbar Stress Fracture Training Program
Selecting individual exercises is helpful, but many athletes benefit from following a structured program designed specifically for this stage of rehabilitation.
I created a 6-week Lumbar Stress Fracture Strength Program designed for athletes who are currently avoiding axial loading but want to maintain strength and mobility.
The program includes:
4 training sessions per week
Lower body strength without spinal compression
Thoracic and hip mobility in every session
Trunk stability and anti-rotation training
Sled-based conditioning

Final Thoughts
Rehabilitation from a lumbar stress fracture does not mean complete inactivity.
With appropriate exercise selection and programming, athletes can maintain strength, improve mobility, and develop trunk stability while protecting the healing spine.
The key is choosing exercises that minimise spinal compression while still providing a meaningful training stimulus.
This approach helps athletes stay physically prepared and often leads to a smoother return to full training and sport once axial loading is reintroduced.
Frequently Asked Questions About Lumbar Stress Fracture Training
Can you exercise with a lumbar stress fracture?
Yes, many athletes can continue exercising during lumbar stress fracture rehabilitation, provided exercises are selected carefully. Training typically focuses on maintaining strength, mobility, and trunk stability while avoiding movements that place compressive load through the spine, such as heavy barbell squats or deadlifts.
What exercises should be avoided with a lumbar stress fracture?
Exercises that place significant axial loading or repeated spinal extension should generally be avoided during early rehabilitation. These often include heavy squats, heavy deadlifts, barbell lunges, and high-load overhead lifts. Your physiotherapist or clinician can help determine when these exercises can be safely reintroduced.
What are the best exercises for lumbar stress fracture rehabilitation?
Common exercises used during lumbar stress fracture rehabilitation include sled pushes, split squats, goblet squats, single-leg hinge exercises, thoracic mobility drills, hip mobility work, and anti-rotation trunk exercises. These movements help maintain strength and improve movement control without placing excessive stress on the spine.
How long does a lumbar stress fracture take to heal?
Healing time varies depending on the severity of the injury, the athlete’s age, and adherence to rehabilitation guidelines. Many lumbar stress fractures require 8–12 weeks or longer before athletes return to full training, although controlled rehabilitation exercises may be introduced earlier under professional guidance.
Why is hip and thoracic mobility important for lumbar stress fractures?
When mobility is limited in the hips or thoracic spine, the lumbar spine often compensates by moving excessively. Improving mobility in these areas can reduce stress on the injured spinal segment and help restore more efficient movement patterns during sport and training.
When can athletes return to lifting weights after a lumbar stress fracture?
The return to heavy lifting depends on healing progress, symptom response, and clinical assessment. Axial loading exercises such as squats and deadlifts are typically reintroduced gradually once the athlete demonstrates good movement control, adequate strength, and no symptoms during rehabilitation exercises.
Should athletes get a movement assessment during lumbar stress fracture rehabilitation?
Yes. A thorough movement assessment can identify mobility restrictions and motor control deficits that may contribute to spinal stress. Assessments such as the Selective Functional Movement Assessment (SFMA) help clinicians determine appropriate corrective exercises and guide safe progression back to training.
