That’s why Rees created the following dumbbell leg workout. Ideally, you should add strength workouts to your routine two to three times a week. “If you don’t have a leg day in your routine, add this into your weekly plan. It may be tough, but you certainly won’t regret it when you tackle your next long run,” she says.
How to do it: Perform each exercise for 50 seconds, then rest 10 seconds before moving into the next exercise. Performing the exercises once through takes 8 minutes. Rees recommends performing them as a circuit, two to three times through for a total of 16 or 24 minutes.
