1. NOT GETTING ENOUGH SLEEP
Most professional athletes get at least 10 hours of sleep a night. Whilst this is completely impractical for the vast majority of Crossfitters, it does highlight the importance of getting a decent amount of shut eye. No amount of supplements, foam rolling or mobility work will ever compensate for a significant lack of sleep when it comes to recovery and progress.
