  "account": "Exercise pays dividends even when you temporarily halt your routine, according to research from our team. Muscles and liver cells retain a record of every workout session, which could enhance endurance, regulate blood sugar, and aid weight management after inactivity. For decades, experts have viewed exercise as a one-time benefit that diminishes over time, but recent studies suggest otherwise. When you stop training, your maximum oxygen intake, muscle growth, and insulin sensitivity typically return to baseline within weeks. However, contrary to this notion, muscles and liver cells appear to retain exercise memories, enabling you to regain fitness faster than those who never trained before. Our experiments on mice revealed that muscle memory accelerates muscle growth and improves energy efficiency, even in the presence of a high-fat diet. Furthermore, liver cells also store exercise memory and facilitate more efficient fuel delivery to the muscles. These findings indicate that cellular memories of exercise may endure across generations, potentially conferring health advantages to offspring born to parents who engaged in regular physical activity.",
  "summary": "‘Use it or lose it’ isn’t quite true when it comes to the health benefits of exercise. Cells across the body retain a memory of training that lasts longer than once thought.",
