Muscle Growth Mechanics
To excel in bodybuilding, one must harness the power of concentration and intensity. The body reacts to stress as a survival mechanism, prompting muscle growth when it perceives inadequacy.

How does one "train like a bodybuilder"?

Why can I lift almost double the weight with somewhat good form but not the best mind-muscle connection?
