Gradually increasing workout intensity is essential to avoid injury and enhance performance. Sudden intensity spikes can lead to muscle strains, joint injuries, and overtraining, setting back progress. A gradual approach allows the body time to adapt to new stresses, improving strength and endurance effectively. This method also fosters consistency, reducing the likelihood of burnout and ensuring a safer fitness journey. Progression, while necessary for improvement, should be methodical and tailored to individual fitness levels and goals.
