The general medical recommendation is 150 minutes per week of moderate-intensity physical activity, like walking. This contributes to overall health benefits, including decreased disease risk, weight and stress management, reduced stress, and better sleep. The great thing about those 150 minutes is that everything adds up! Just a 15-minute walk to the train and a 5-minute walk to work five days a week round trip puts you at 200 minutes of walking for the week!
