Does sweating at the gym break wudu?

No. Sweat, heavy breathing, a long workout and drinking water don't break wudu. Only the usual things do: using the toilet, passing wind, deep sleep or losing consciousness. Hard training can make a few of these more likely, so it helps to check yourself before you pray.
What does not break wudu
- Sweating, however much, and wiping it off with a towel.
- Panting and heavy breathing, even after sprints or heavy sets.
- Drinking water or eating a snack between exercises.
- Lifting, running, stretching and swimming.
- Touching gym equipment or other people's sweat.
Sweat is pure in Islam, so it affects neither your wudu nor your clothes. See Is sweat najis in Islam?
What can break it during a workout
The Prophet ﷺ said, "The prayer of a person who does Hadath (passes urine, stool or wind) is not accepted till he performs the ablution" (Sahih al-Bukhari 135). Exercise can bring these on without you noticing:
- Passing wind: heavy squats, deadlifts and core work often cause this.
- Leaking urine: some people leak a little when jumping or running.
- Deep sleep or fainting: dozing off in the sauna or on a mat, or feeling faint after a hard session.
The schools differ on a few more. Hanafis say flowing blood, such as from a deep scrape or nosebleed, breaks wudu. Shafi'is and Hanbalis say touching your private part directly breaks it, which can happen when adjusting kit. Shafi'is also count skin contact with the opposite sex. Follow the school you learned from. See What breaks wudu? and Does bleeding break wudu?
When you are not sure
Gym sessions are noisy and distracting, so doubt is common. A man once asked the Prophet ﷺ about imagining he had passed wind during prayer. He replied, "He should not leave his prayers unless he hears sound or smells something" (Sahih al-Bukhari 137). In other words, if you only feel unsure, your wudu stays valid. Renew it only if you are certain something broke it.
Practical gym tips
- Make wudu at home before the session or right after it, whichever fits your prayer time.
- If your wudu is still valid after the workout, you can pray straight away in clean clothes.
- Take off wrist straps, tape, gloves and waterproof plasters first, so water reaches your skin. For genuine medical dressings, see Can I make wudu with a cast or bandage?
- If you're not sure and have two minutes, just renew it. It costs nothing.
- Sweat, heavy breathing and long workouts don't break wudu.
- Passing wind, urine, deep sleep and fainting do.
- Schools differ on bleeding and touching the private part.
- Doubt alone doesn't break wudu; certainty does.
