Why don't I get sore after workouts anymore?

David Buer
Our bodies are incredible machines that are made to adapt to almost any situation or stress we encounter. You get sore when new stress and increased intensity creates small tears and damage in muscle tissue. After muscles rest and rebuild, they are stronger and more fit.
If you don’t change up your routine, your body will adapt and you won’t feel that same muscle soreness. But increasing the number of reps, weight or time you work out; reducing rest periods; and varying types of exercise and activities along with effort will allow you to create change, improve and grow. That’s true for any aspect of life -- we can’t increase knowledge without facing challenges. The same is true for your body -- new challenges and changes mean growth.
Muscle soreness occurs when the muscle is stressed to the point that it slightly tears, causing what is called delayed onset muscle soreness. Once the muscle is healed, a few days after the initial exercise, the muscle becomes stronger. Repeatedly doing the same exercise routine will not continue to strengthen the muscle, therefore there will be no soreness.
