The prescription of rest for chronic pain has contributed to a widespread misunderstanding that exercise and chronic pain are incompatible. They are not. Exercise is among the most effective treatments for the majority of chronic musculoskeletal pain conditions. The question is not whether to train but how to train in a way that is progressive, appropriate to the pain condition, and not unduly provocative.
The Pain Monitoring Approach
The most clinically useful guide for training with chronic pain is the traffic light system. Green: pain during or after exercise is absent or minimal, training can be progressively loaded as normal. Amber: pain during exercise is moderate but settles within 24 hours and does not leave you worse than before, training can continue at this level. Red: pain significantly worsens during exercise and does not settle within 24 hours, training load should be reduced. The goal is to stay in the green and amber zones consistently, gradually expanding what falls within those zones.
Modifying Exercise for Common Pain Conditions
- Chronic low back pain: avoid high-load spinal flexion under load, prioritise hip hinge mechanics, core stability, and hip and glute strength
- Knee pain: avoid deep knee flexion with load until quadriceps strength is adequate, use step-down exercises as a key assessment and training tool
- Shoulder pain: avoid overhead pressing until shoulder mobility and rotator cuff function are established, prioritise pulling exercises
- Hip pain: avoid extreme hip internal rotation under load, strengthen the gluteals specifically through hip abduction and extension patterns
The Most Important Principle
Consistency matters more than intensity in chronic pain rehabilitation. Training three times per week at a moderate intensity that stays within the amber zone consistently is more therapeutically effective than training hard once a week and spending the remaining days managing increased pain. Progressive loading over weeks and months is the mechanism, and that requires showing up consistently more than it requires any single session to be excellent.
