I often hear from people who are desperately wanting to be jacked but who, let’s say, don’t want to give up running marathons on the side, for endurance. While this is a very nice for overall health, you’re only making getting jacked a whole lot more difficult.
Specificity is the principle of hypertrophy that addresses, in the most straight-forward of terms, how to direct our training to get the results we want. Let’s say you wan’t to become an elite level sprinter. Following the principle of specificity, you better be doing a lot of sprinting (or sprinting-like activities). Seem’s pretty simple and yet many new lifters get this wrong all the time.
