Exercise is one of the most powerful recovery tools available. It directly addresses the neurobiological damage of addiction while providing structure, community, and natural reward.

The neuroscience

Exercise increases dopamine receptor density (countering anhedonia). Promotes BDNF release (brain healing). Reduces cortisol (stress management). Improves sleep quality. Produces endorphins and endocannabinoids (natural mood elevation).

Best types for recovery

Aerobic (running, cycling, swimming): strongest evidence for dopamine recovery and mood improvement. Strength training: builds confidence, discipline, and body repair. Yoga: combines physical activity with mindfulness. Walking: accessible to everyone, immediate benefits.

Getting started

Start small. A 10-minute walk counts. Build gradually. Do not use exercise as a substitute for treatment. Find activities you enjoy. Exercise with others when possible for social support.

Building a routine

Consistency matters more than intensity. Morning exercise sets a positive tone. Track your activity. Join a gym, class, or running group for accountability.
