多年整天久坐之后，我开始实行一条简单的规则：每天活动20分钟。有些日子是跑步，其他日子只是拉伸或长时间散步。我的精力和睡眠改善得远超预期。对你来说，哪些小习惯带来了最大的改变？

After years of sitting all day, I started a simple rule: 20 minutes of movement daily. Some days it's a run, other days just stretching or a long walk. My energy and sleep improved way more than expected. What small habits made the biggest difference for you?
