The exercise I shall discuss in this -- the first of a new series of articles on muscle definition specialization of a particular body part -- is the One Leg Lunge. Why it was ever forgotten for even a moment I cannot say because it works perfectly for everyone, no matter whether he has short or long thigh-bone lengths!

It is the one exercise that drastically influences the definition of the thighs at the hipline -- that mark of the champion that sets him apart from all other bodybuilders -- a criterion of muscle ``drama'' that is unforgettable to judges and audiences alike -- the facet of muscular development that wins prizes.

Definition of the thighs at the uppermost part is quite commonly seen in most championship Olympic lifters which is easily understandable. The One Leg Lunge is a split and all lifters practice this in their regular workouts.

But for purely definition purposes -- used in conjunction with your regular Squatting, Leg Curling, Leg Extensor programs -- a heavy weight is not needed. Indeed, a lighter weight works much better because a greater, more extensive split can be performed. Used in several sets of high reps once or twice each week it will not be long before your entire upper leg takes on a razor-sharp definition in which the muscles look like wire cables writhing and twisting under the skin!

Really there is no reason why this fine exercise should not find its way into your leg program at all times, for the following suggestions show why it is so effective:
