HMB, or beta-hydroxy beta-methylbutyric acid to give it its Sunday name, is an active metabolite of the amino acid leucine. In English, HMB inhibits degradation of protein while you are are undergoing resistance training.

Why do Monster Supplements recommend HMB supplements? Because while HMB does not exactly promote muscle growth, it is very effective at preventing muscle breakdown - enabling you to train harder, longer.
