I've heard of lactic acid before & how it fatigues your muscles if you stay in the gym too long. What exactly is it? Why does it affect training?

The cells in your body go through cellular respiration to convert glucose into pyruvate (pyruvic acid) and ATP which is the fundamental energy building block of cells. Cellular respiration involves an oxidizing agent and a reducing agent, the most common oxidizing element is 02(oxygen). In the absence of oxygen, however, cells cannot complete cellular respiration and actually go through a process called fermentation. one form of fermentation is lactic acid fermentation in which the waste given off is lactic acid. Lactic acid thus gets into your muscles and causes a familiar feeling known as cramping. Basically it means you are not taking in enough oxygen to fuel your muscle cells to complete cellular respiration and create more energy and instead your muscles are producing lactic acid.

It's a substance produced in a working muscle that is responsible for the "burn" associated with lifting weight for multiple reps. The increasingly uncomfortable sensation usually eventually forces the trainee to end the set.
No brain, no gain.
"The fitness and nutrition world is a breeding ground for obsessive-compulsive behavior. The irony is that many of the things people worry about have no impact on results either way, and therefore aren't worth an ounce of concern."--Alan Aragon
