Question: When I'm sore the day after I work out, do I need to push through it, or rest?
Answer: When your muscle is sore it is from muscle being broken down in the workout. Think of it as micro-tears in the muscle body. To get stronger you have to give your body time to heal and provide it with adequate protein to help repair. I wouldn’t train the muscle until the soreness goes away as it is still in the repairing process. This is often referred to as overtraining as you try to work the body harder and harder and see no results because your body can’t recover. Hope this helps!
