Proper technique is essential in achieving benefits from any exercise.
On the June 2 Early Show, fitness contributor Minna Lessig demonstrated some common exercise mistakes and talked about how they can affect a workout. Lessig says that injuries can result if exercise is not done properly, and poor posture is one of the key culprits of injuries. Improper posture and form can also affect results, since the wrong muscles can be used when the form is wrong. Most shoulder exercises work the anterior deltoid, so we want to take advantage of the lateral raise, working the medial deltoid. How far forward a person leans depends on their shoulder anatomy.
