Sore muscles: should you wait before training again?
The day after your first session, walking downstairs becomes a challenge. Here is what you can do straight away, what is worth postponing, and the signs that go beyond ordinary soreness.
The essentials
- No need to stay still: move gently, as long as it does not increase the pain.
- Wait until the pain has gone before repeating the same hard effort.
- Muscle pain that lasts more than three days deserves medical advice.
Do I have to rest for as long as it hurts?
No, complete rest is not the advice. Australia’s government-funded health information service recommends resting the affected muscles while continuing gentle exercise, provided it does not increase the pain. Walking, easy cycling, working your upper body when it is your thighs that ache: all of that remains possible.
What is better postponed is the effort that caused the pain. The medical library of the US National Institutes of Health advises avoiding high-impact activities and weight lifting while a muscle is injured or painful. In other words, the squat session can wait until you walk downstairs normally again. That delay is part of training, and none of it is time lost.
How do I tell soreness from an injury?
Soreness fades within a few days, while an injury leaves marks. After an unfamiliar effort, pain from overusing a muscle affects the areas that worked, and you usually know which session caused it. A sprain or a strain looks different: the area is swollen or bruised, and you cannot put weight on it or use it normally.
Time is the second test. The US National Institutes of Health sets the threshold at three days: beyond that, muscle pain warrants medical advice, as does severe unexplained pain, or swelling or redness around the muscle. And with a real injury, trying to push through causes more damage and delays healing, warns the health department of the Australian state of Victoria.
What actually brings relief?
Simple measures: heat, gentle movement, sleep. Applying heat to the sore area is among the tips from Australia’s health information service. The US National Institutes of Health adds gentle stretching after a long period of rest, massage, which often helps pain from overuse, and plenty of sleep.
Think about water too. Drinking before, during and after exercise is one of the steps listed to lower the risk of muscle aches, and the advice counts double when the session takes place in the heat. None of this erases soreness in an hour. The aim is to stay mobile and comfortable while the muscle does its work.
How can I hurt less next time?
By building up little by little. Begin slowly and increase your workouts gradually: that is the advice from the US National Institutes of Health and the Australian health authorities alike, and it is the first thing forgotten when motivation is fresh. Twenty minutes this week, twenty-five the next: move forward at that pace.
Warming up and cooling down matter as well. Five to ten minutes of brisk walking or light jogging before the effort, then a gradual slowdown and some stretching at the end: according to Victoria’s health department, this routine helps to reduce muscle soreness and stiffness, even though the evidence that it prevents injury is thin. It also recommends at least one recovery day every week, preferably two.
The day after a hard session
Do
- Walk or cycle gently to stay mobile.
- Apply heat to sore muscles.
- Drink before, during and after your session.
- Warm up for five to ten minutes and finish by slowing down.
Avoid
- Repeating the same hard session while the muscle still hurts.
- Pushing through on an area that is swollen or bruised.
- Suddenly increasing the length or intensity of your sessions.
When to seek advice
See a doctor if the pain lasts more than three days, if it is severe with no explanation, or if the area is swollen, red or cannot take your weight. Dark urine the colour of tea or cola, with pain far worse than you would expect and marked weakness, needs immediate medical attention.
