Lumbar Stress Fracture Strength Program

This program is designed for athletes with a lumbar stress fracture who have progressed beyond the acute protection phase and are currently in a non-axial loading rehabilitation stage. The primary objective is to maintain and progressively develop strength, mobility, and movement control while protecting the healing lumbar spine from compressive loading.

During this stage of rehabilitation, axial loading patterns such as heavy squatting or barbell spinal loading are avoided. Instead, the program emphasises unilateral lower-body strength, sled-based work, isometric force production, and supported strength exercises that allow meaningful strength stimulus without excessive spinal compression.

A central focus of the program is restoring and maintaining thoracic spine mobility and hip mobility, which helps reduce compensatory motion and stress through the lumbar spine. Thoracic rotation and hip rotational mobility are incorporated in every session to support efficient movement mechanics and reduce extension or rotation demands at the injured segment.

The strength component prioritises general strength and trunk control, using exercises that challenge anti-rotation, single-leg stability, and multi-planar control while maintaining natural breathing patterns and minimizing excessive spinal bracing. Upper body pushing and pulling patterns are included weekly to preserve whole-body strength and training balance.

Lower body strength is developed through sled pushes/drags, goblet variations, split squat patterns, and single-leg hinging exercises, which allow the athlete to maintain leg strength and work capacity during the period where traditional bilateral axial lifts are restricted.

The program is structured as four sessions per week over six weeks, allowing consistent exposure to mobility work, strength maintenance, and trunk stability development while respecting tissue healing timelines.

Overall, the intent of this program is to bridge the gap between early rehabilitation and a return to loaded strength training, ensuring the athlete maintains strength qualities, improves mobility and movement control, and remains physically prepared to progress into higher-load training once axial loading is clinically appropriate.
