What are the symptoms of lactic acid buildup in the muscles?

The symptoms include a burning feeling in your muscles, cramps, nausea, weakness, and feeling exhausted. It’s your body’s way to tell you to stop what you’re doing

The symptoms happen in the moment. The soreness you sometimes feel in your muscles a day or two after an intense workout isn’t from lactic acidosis. It’s your muscles recovering from the workout you gave them.
