muscle burn
Lactic acid sensation
Muscle burn is the sharp, fatiguing sensation in muscles during intense exertion, caused by lactic acid buildup.
Athletes often push through it or chase it as a sign of effective training: Feel the burn.
The phrase distinguishes this expected discomfort from injury pain: That's just muscle burn—you can keep going.
