Returning to exercise after a holiday break requires caution to prevent injuries. Muscles can lose up to 20% of their strength and endurance after a short break, making them susceptible to tears from sudden high loads. Tendons and ligaments also become stiffer and lose elasticity, increasing tear risk by 30% if stressed abruptly. Holiday diets high in sodium and sugar can cause joint inflammation, which is worsened by high-impact activities. Experts advise starting slowly and gradually increasing intensity to allow the body to adapt safely.
