Managing stress contributes to physical fitness by allowing the body to perform at its best. When stress is managed effectively, it can lead to better mental clarity, improved energy levels, and enhanced motivation for workouts. High stress can hinder performance and recovery, leading to fatigue and a lack of progress. Utilizing techniques such as deep breathing, yoga, or time management can reduce stress, positively impacting overall fitness. Maintaining a low-stress environment supports consistent exercise habits and fosters a more rewarding fitness experience.
