Does anyone know what this could be?

I’ve started to notice this happening after working out.

Looks like a rash from skin irritation to me. What kind of workouts do you do and do you shower immediately afterwards? Are you new to working out?

Could be from anything, the following ideas are some examples that pop to mind:
- your workout gear is made from materials that irritate your skin, either always or when exposed to sweat
- Your skin is blocked with impurities so the gunk and sweat can’t come out
- You don’t shower immediately after the workout and sweat starts to irritate your skin
- There’s something in workout machines/mats/whatever you touch with your skin that causes irritation

If you’re new to working out, there’s also the chance that it’s just regular winter rash that showed up at the same time you started working out, or the sweat etc triggers it. I live in Finland and most people I know have some sort of skin issues (Rash, dryness, cracking) in the winter because the outside air is trying to kill us and central heating is trying to suck all moisture out of our skins indoors.

While you try to troubleshoot what might cause this (check shirt material and try showering immediately, at least), in all cases I’d take care of washing and moisturising regularly, and adding gentle exfoliation to your routine once it clears.

Note: I’m not a doctor or a dermatologist and this should be taken as words from a friendly internet stranger, not as medical advice or diagnosis.

Looks like heat rash from blocked sweat ducts.

I get a rash like that when I’m overheated, sweating profusely, dehydrated, and my electrolytes are low (generally depleted through sweat). My body tingles too.

Generally an electrolyte drink and a glass of water clears it in 20min. Then keeping well hydrated for the rest of the day including extra electrolytes if needed.

This usually happens when I’m hiking in a very hot (to me) country for a number of hours, not after a gym workout.

Try hydration, electrolytes, and a cooling shower, if that doesn’t help have it checked out by your doctor.
