If you experience delayed onset muscle soreness be sure to allow your muscles to recover between 48-72 hours before hitting the weights hard again, recommends Rick Richey, a certified celebrity trainer and owner of
R2Fitness in New York City. Delayed onset muscle soreness usually occurs after intense, high-level exertion workouts, and rest is necessary to allow your muscles time to recover and develop strength. But that doesn’t mean you can’t work out. You can do cardio or focus on another type of workout while you wait for your legs to recover.
