The thing about lactic acid that nobody explained to me in school
you know that burning feeling in your legs during a long run or a tough squat set? that's lactic acid accumulating faster than your body can clear it. your muscles are essentially saying: we are at capacity, shutting down now.
for a long time I thought that was just… what exercise felt like. a hard limit. a fixed ceiling.
but beta-alanine changes the equation. it increases carnosine in muscle tissue, which acts as a buffer — slowing the drop in pH, delaying the point at which your muscles give out.
it doesn't eliminate the burn. nothing does. but it pushes the wall back. gives you more time, more reps, more distance before your body taps out.
which means the ceiling isn't actually fixed. it just felt that way.
