It is one of the most common beliefs on the gym floor: the sorer you are the next day, the better the session was, and if you are not sore, you did not train hard enough. It feels intuitive, and it is wrong. So does muscle soreness mean a good workout? Not really. Soreness tells you something, but not what most people think. Here is what DOMS actually indicates, why it fades as you progress, and how to judge a session properly, from the trainers at Hammer’s Gym in Nunawading.
What DOMS actually is
Delayed-onset muscle soreness is the ache and stiffness that arrives 24 to 48 hours after training. It is caused by microscopic damage to muscle fibres and the inflammation that follows, particularly from eccentric (lengthening) work such as lowering a weight, the descent of a lunge or running downhill. It is your body’s response to a new stimulus. For how to treat it, see how to recover from DOMS.
Soreness measures novelty, not effectiveness
The key word is new. You get sore when your body meets something it is not yet efficient at recovering from: a new program, new exercises, a tempo change, more range of motion, or simply being new to training. That is when soreness peaks, because your body has been shocked and has not yet adapted. It says nothing about how many calories you burned, how much muscle you stimulated or how much stronger you are getting. A beginner’s first set of bodyweight lunges can produce three days of agony; an experienced lifter’s heavy, productive squat session may produce none.
Why soreness fades as you improve
As you progress, you will notice soreness arrives less often and less intensely. Some people read that as a sign they are no longer training effectively, and start chasing soreness with random new exercises. In reality it is the opposite: your body has learned to cope with the stimulus and recover faster. This is called the repeated bout effect, and it is a sign of fitness, not a lack of it. The consistent, progressive training that produces the least soreness is usually the training that produces the most results.
When soreness is a warning
Mild to moderate soreness that fades within two or three days is normal. Soreness that is severe, lasts longer than four or five days, sits in a joint rather than a muscle, or is sharp rather than dull is not DOMS; it is a sign you did too much, too soon, or that something is injured. Back off and get it assessed. Constantly chasing extreme soreness also tends to leave you too sore to train well in the next session, which costs you more than it gains.
Better ways to judge a workout
- Did you progress? More weight, more reps or better form than last time is the real measure. Track it; see how to track gym progress.
- Did you hit your planned volume and intensity? Completing the program is a good session, sore or not.
- How was your technique? Clean reps through a full range beat sloppy reps to failure.
- How do you feel 24 hours later? Energised and ready to train again is the goal, not crippled.
- Are you improving over months? Strength, measurements and photos across a training block tell the story.
Should you ever aim for soreness?
No, but do not fear it either. Introduce new exercises with lighter loads and fewer sets so the first-week soreness is manageable, then progress steadily using progressive overload. Warm up properly, recover well and let soreness be an occasional side effect rather than a target. Read six common gym myths for the other beliefs worth retiring.
