What is DOMS and when does it show up?
Delayed onset muscle soreness, or DOMS, is muscle pain after intense exercise. It begins one to three days later, usually lasts a few days and rarely lasts more than five. It is most common after a new workout or a new sport, and after eccentric movements, where the muscle lengthens under tension, such as the lowering phase of a curl or walking downhill.
Why do you stop getting sore as you train?
Your muscles adapt. The same exercise tends to cause less damage and less soreness the next time you do it, which is why a familiar routine feels easier on your body than a new one. People also differ. A 2006 study that gave the same eccentric exercise to young men found that some showed much less muscle damage than others, so two people can follow the same plan and feel it very differently.
Does no soreness mean the workout failed?
No. Cleveland Clinic says the idea that you need pain to gain is not necessarily true. Soreness tells you that something was new or hard. It does not tell you how much you improved.
What are better signs of progress?
- More reps or more weight than last time.
- The same reps feeling easier.
- Better form and a fuller range of motion.
- Sticking to your planned sessions week after week.
When should soreness worry you?
See a doctor if the pain does not improve with rest, lasts more than a week, is sharp and constant, comes with severe swelling or dark or bloody urine, or stops you from moving a body part.
What should you do next session?
If you were not sore, keep going. If you want a fresh challenge, change one thing at a time, such as a small weight increase or an extra rep, rather than chasing soreness.
