Aching muscles 1 to 3 days after new exercise are normal. How long soreness lasts after 50, what eases it, and the signs that mean see a doctor.
Dull, tender aching in your muscles a day or two after new or harder exercise is normal, harmless and usually settles within 3 to 5 days. It is called delayed onset muscle soreness (DOMS). Sharp pain during exercise, pain in a joint, swelling, dark urine or soreness that is severe or not improving after a week is different and needs assessment.
What DOMS is
DOMS appears after movements your muscles are not used to, especially those that involve lowering a load, such as walking downhill, descending stairs, lowering into a squat or a slow lowering phase in the gym. Researchers describe it as minor damage to the muscle fibres followed by a local inflammatory and repair response, which causes tenderness, stiffness and reduced force for a few days.
The typical pattern is:
| Time after exercise | What you notice |
|---|---|
| 0 to 12 hours | Usually feels fine, or mild fatigue |
| 12 to 24 hours | Ache and stiffness begin |
| 24 to 72 hours | Peak soreness, tender to touch, stiff on stairs |
| 3 to 5 days | Fading |
| Up to 7 days | Gone, or only a faint trace after a very large change |
Soreness is not a measure of a good workout. You can progress well with little or none, and severe soreness usually means you did too much, too soon.
Does age make it worse?
Many people over 50 report that soreness lasts longer or feels worse. The honest answer is that the research is mixed, and the biggest factor is how unfamiliar the exercise is, not your age alone. A review of eccentric exercise in older adults found that muscle damage was largely avoided when new eccentric exercise was introduced gradually, and that repeated sessions made the soreness response much smaller. This is the “repeated bout effect”: your muscles adapt quickly after the first session.
So if you are returning to exercise or starting strength training, expect the first one to two weeks to be the sorest and for it to fade as the routine becomes familiar. Our guide to eccentric training explains why the lowering phase is a common trigger.
How to ease soreness
Evidence for any single recovery method is modest. A meta-analysis of recovery techniques found that active recovery, massage, compression garments and water immersion reduced soreness to some degree, with massage the most effective for soreness and fatigue. Some popular methods showed little effect. In practice:
- Move gently. A short walk, easy cycling or light mobility work increases blood flow and often eases stiffness. This is a form of active recovery.
- Try massage or a warm shower. Both are reasonable if they feel good.
- Eat enough protein and drink enough fluid. Your body repairs muscle between sessions. Our guide to protein after 50 gives realistic targets.
- Sleep. Aim for 7 hours in bed, as most tissue repair happens during sleep.
- Be patient. Soreness settles by itself.
Be cautious with anti-inflammatory painkillers. They can irritate the stomach and strain the kidneys, particularly if you have kidney disease, high blood pressure, are dehydrated or take certain heart or blood pressure medicines. Ask a pharmacist or doctor before using them regularly for exercise soreness.
How to prevent heavy soreness
- Progress gradually. Add 5 to 10 per cent more load or one extra set per week rather than doubling your workload.
- Start easy. In your first two weeks of a new routine, stop with 3 to 4 reps in reserve.
- Introduce lowering phases slowly. Do a few slow step-downs or sit-to-stands first, then build up.
- Warm up. Five to ten minutes of easy movement helps, though it does not prevent soreness entirely. See warm-up routine after 40.
- Keep your routine regular. Two sessions a week keep the adaptation active, in line with WHO advice to do muscle strengthening on at least two days a week.
A sensible first fortnight when you start something new
If you are starting strength work, a new class or a long walk programme, this pacing keeps soreness manageable:
| Week | Strength work | Walking or cardio |
|---|---|---|
| Week 1 | 1 set of 8 to 10 reps per exercise, light load, 2 sessions | 20 to 25 minutes, flat, easy pace |
| Week 2 | 2 sets, same load, 2 sessions | 25 to 30 minutes, add a gentle slope |
| Week 3 | 2 to 3 sets, add a small amount of weight if all reps feel easy | 30 minutes, one brisk segment |
| Week 4 onwards | Progress one thing at a time: load, sets or reps | Build time before intensity |
Leave at least one day between sessions for the same muscles. If you are still very sore when the next session is due, repeat the previous week rather than moving on. This is also a good time to learn your own pattern: some people are sorest after the second day, not the first, and a few feel almost nothing. Both are normal.
Soreness after a social event, a trek or a long walk on stairs, such as a day around Batu Caves or a hill hike, follows the same rules. It is the sudden jump in downhill or stair work that causes it, so build up your stairs and slopes in the weeks beforehand.
Training when you are sore
You do not need to stop. Light activity is fine, and you can train other muscle groups while one area recovers. Reduce the load on the sore muscles, avoid heavy lowering work, and skip high-intensity sessions on legs that feel weak or unstable. Soreness often feels worst at the start of a session and eases as you warm up. If it does not ease, or if it changes how you move, rest.
When it is not DOMS: warning signs
Stop and seek advice if you notice:
- Sharp pain during exercise, or a sudden pop or snap.
- Pain in a joint, a tendon or the back of the knee or calf, rather than the muscle belly.
- Swelling, bruising, warmth or redness in a muscle or leg.
- Soreness that is severe, worsening or still strong after 7 days.
- Marked weakness or being unable to bear weight.
Seek urgent medical care if you have severe muscle pain and swelling after unusually intense or unaccustomed exercise together with dark, tea- or cola-coloured urine, extreme weakness, nausea or reduced urine. This can indicate rhabdomyolysis, a serious muscle breakdown that can harm the kidneys. Heat, dehydration and certain medicines raise the risk. In Malaysia’s climate, train in the cooler part of the day and drink regularly, as in staying hydrated in tropical heat.
Also tell your doctor if you take a statin and develop new, widespread muscle aches or weakness. Statin-related muscle symptoms need assessment and should not be put down to exercise alone.
Key takeaways
- A dull ache 1 to 3 days after new or harder exercise is normal. It usually peaks at 24 to 72 hours and settles within about a week.
- Gradual progression is the best prevention, and soreness gets smaller as your body adapts.
- Gentle movement, sleep, protein and massage can help. Be careful with anti-inflammatory painkillers.
- Sharp pain, joint pain, swelling, dark urine or soreness that is not improving after a week needs assessment.
