Should You Work Out When Sore? A Simple 1-10 Rule

It is Wednesday. You finally have a class booked, or a free half hour after the kids’ bedtime, and your legs are still aching from Monday’s session. Part of you thinks pushing through is the “committed” thing to do. Another part wants to stay on the sofa. So, should you work out when sore? Most of the time the answer is yes, with some changes. Sometimes the answer is a clear no. Here is how I help the parents I coach in Archway tell the difference.

Normal soreness vs pain that means stop

Before deciding anything, work out what kind of sore you are.

Normal muscle soreness (DOMS)

• A dull, achy, tender feeling in the muscles you trained.
• Usually on both sides fairly evenly.
• Starts a day or so after training and peaks around day two.
• Feels worse when you first move and eases as you warm up.

This is very common, especially when you are new or doing something different. My post on how long DOMS lasts covers the usual timeline.

Pain that means stop and get it checked

• Sharp, stabbing or sudden pain.
• Pain in or around a joint, rather than the belly of a muscle.
• Pain on one side only that came on during a specific movement.
• Swelling, bruising, or difficulty putting weight on a limb.
• Pain that is getting worse after a few days instead of better.

Those signs can point to a strain or other injury. The NHS page on sprains and strains explains the symptoms and when to see a GP, call NHS 111 or go to A&E. Do not train through these. Get advice from your GP or a physio first.

Should you work out when sore? My simple 1 to 10 rule

Rate your muscle soreness from 1 (barely there) to 10 (cannot get off the toilet without holding the sink).

• 1 to 3, mild: train as normal. Your warm up will probably make it disappear.
• 4 to 6, moderate: train, but change the plan. Work different muscles, go lighter, or do a lower-intensity session.
• 7 to 10, severe: make it an active recovery day. Walk, stretch, do gentle mobility. Save hard training for when it settles.

And at any level: if you feel unwell, feverish or completely exhausted, rest. A missed session will not undo your progress.

What to do on a sore day

Option 1: Train a different area

Legs wrecked from squats and lunges? Do an upper body and core session: push-ups against the worktop, rows, dead bugs and planks. Arms sore? Work your legs. This is why many plans split upper and lower body across the week.

Option 2: Same muscles, much lighter

Very light work on sore muscles can actually make them feel better. Do the same moves with half the weight, or no weight at all, for 2 easy sets. Stop well short of tired.

Option 3: Active recovery (20 to 30 minutes)

1. 10 minutes of brisk walking, perhaps on the school run or around the block.
2. Cat and cow: 8 slow reps.
3. Glute bridges: 2 sets of 10.
4. World’s greatest stretch: 3 per side.
5. Hip flexor stretch: 30 seconds each side.
6. Child’s pose with slow breathing: 1 minute.

My 10-minute mobility routine is another good option for sore days.

Why working out through soreness is usually fine

Muscle soreness on its own is not a sign of damage you need to protect. For most healthy adults, moving when you are mildly sore is safe, and you will often feel looser afterwards. The NHS physical activity guidelines recommend being active every day in some way, so even on a very sore day, a walk counts.

Where people go wrong is treating every session like a test. If you train hard every time, with no easier days and poor sleep (hello, parenthood), soreness builds up and so does the risk of injury. Mix hard days with easier ones.

How to be less sore in the first place

• Build up gradually, especially after a long break.
• Keep a regular routine. Two sessions a week, every week, beats one huge session.
• Warm up before and cool down after.
• Sleep and eat as well as family life allows, with some protein at every meal.
• Plan rest. My guide to rest days and recovery shows how to fit them into a busy week.

Coming to class when you are sore

I would always rather you came to class sore and told me, than stayed home. In my SYP Bootcamp classes, every exercise has an easier and harder option, and with a maximum of 10 people I can adjust your session on the spot: lighter work for sore legs, more upper body, or extra mobility. If stiff hips and a tight lower back are your usual complaint, the SYP Unlock hip and back mobility class is a great choice for a sore week.

FAQs

Is it OK to work out with sore muscles?

Yes, for normal mild to moderate muscle soreness. Train a different area, go lighter or choose an active recovery session. If the pain is sharp, in a joint or getting worse, stop and get it checked.

Should I skip the gym if my legs are sore?

You do not need to skip it. Do an upper body session or a gentle walk and mobility instead, and come back to hard leg work once the soreness has eased.

Does working out when sore make it worse?

Light exercise often makes normal soreness feel better. Very hard training on already very sore muscles can make it last longer and increase injury risk, so scale the session down.

How do I know if it is soreness or an injury?

Soreness is a dull, even ache that eases as you warm up and fades within a few days. Injury pain tends to be sharp, located in one spot or joint, may come with swelling, and does not improve. If in doubt, see your GP or a physio.
