Not getting enough rest and too much too soon tend to produce most of the injuries I see in the office.
1. Running too much too soon. Coming back from an injury? Now’s the time to take things slowly to stay healthy. Follow the standard rule of upping your mileage by only 10 percent each week. 2. Refueling badly. After hard runs, grab a high-carb snack, then a meal with carbs and protein to rebuild muscle.
