How much weight gain from sore muscles?

After a heavy leg day at the gym, my muscles get super sore, and I feel a bit heavier. Can sore muscles actually cause some temporary weight gain? How much is typical?

OMG, yes! Just last week after a really tough workout, my muscles were so sore, and the scale was up by almost 1.5 kg. I panicked initially, but then read it's due to inflammation and water retention in the muscles. It went down in a few days as the soreness eased. Super normal!

Sore muscles just make me crave biryani and pakoras, so for me, it's probably actual weight gain! Haha. But seriously, it's mostly inflammation and fluid retention. Your muscles are repairing themselves, so they hold onto more water. Don't mistake it for fat!

True, DOMS (Delayed Onset Muscle Soreness) often leads to a slight temporary weight increase. Your body retains water to help with muscle repair.

Yeah bro, after a killer leg day, my scale always goes up a bit. My trainer said it's just water retention because muscles are recovering. Nothing to worry about, just means you worked hard! Keep hitting the gym.

I used to freak out every time I saw a small weight increase after a heavy workout, thinking I was doing something wrong! But then I learned it's just your body's natural response to muscle repair, with inflammation and fluid. It goes away. So don't worry, it's part of the process!

Normally, a slight temporary gain from sore muscles is fine. But if you're experiencing extreme pain, swelling, or prolonged weight changes that don't seem to resolve, it's always best to consult a doctor. Sometimes, more serious issues like rhabdomyolysis can cause similar symptoms, so better to be safe.

When your muscles are sore, it's often due to micro-tears and inflammation. Your body sends fluids to the area for repair, which can temporarily cause a slight increase in scale weight. This isn't fat, it's just water retention related to muscle recovery. It should subside as your soreness reduces.
