Will running when my legs are still sore from a workout hurt my strength gains?

If you\'re beginning a workout program, your legs may be sore from new stress. If running is part of your first week\'s plan, it\'s fine to work through the soreness; but if you\'re still hurting after a week, stop running. Instead, rest more between workouts. That said, long, slow distance runs hurt your strength gains, whether you\'re sore or not. Sprints and intervals complement strength training while improving your cardiovascular system.
