Weight-lifts, body building, pilates and those types of disciplines are distinct from weight training because they are sports and body building weight training is applied by athletes as an exercise to acquire body mass muscle and greater strength on their muscles.

Muscle building weight training is a type of strength training. Applying these types of exercises will increase muscular strength and size instead of muscular endurance and flexibleness that different disciplines are concentrated on, like aerobics, yoga and pilates.

For example, Body Building Workouts are some of the most misunderstood methods in the sports industry for getting lean muscle mass and natural strength. They usually involve push-ups, pull-ups and dips, but those are not workouts for getting mass muscle. If you want to get mass muscle like the professionals, you have to know first the different types of weight training exercises.

Resistance Training vs. Weight Training

Whilst weight training experiences its resistance at the initial movement of the body when the muscle creates a heavy effort to get over weight mass, resistance training implies use of hydraulic resistance to contraction instead of graveness. Hydraulic resistance provides an equal measure of resistance throughout the movement

When the movement is restricted to one joint and one muscle group is called isolation exercise. The quadriceps on an extension is an example of an isolation exercise. To accomplish this, specialized equipment is used to ensure the minimal involvement of other muscle groups; this is to help maintain a correct posture.

When you work numerous muscle groups concurrently you are applying compound exercises and involve movements on more than 1 joint. A leg press is a pure example of this, where movement happens around the hip and knee. Though mainly applied for quadriceps this exercise also involves hamstrings and calves

As you have seen there are different kinds of weight training exercises, but you should focus on what works for you and what you want to accomplish. You should follow a training guide or consult an expert
