Anyone who works out, runs, bikes or does any type of intense exercise, knows about DOMS — Delayed Onset Muscle Soreness.

This is the soreness you feel not right after a workout or exercise, but 24-48 hours later.

But it's also something which, when we address it, not only lessens DOMS, but improves overall recovery and sleep for faster lean muscle gains and fat loss.

At one point it was thought this was caused by just lactic acid build up, but this isn’t the case.

Lactic acid is an acid that starts to build up just before we reach our VO2 Max and can’t go any further in our exercise or workout. (VO2 Max is the Maximum amount, or Volume, of Oxygen (O2) that your cells can utilize during intense exercise, before you burn out.)

But lactic acid actually helps you. Your body can metabolize it (burn it and use it as fuel).

So what really causes DOMS? And how can we prevent it or lessen it?

Let’s see.
