What Is the Difference Between Weight Machines and Free Weights?

Wt machine add wt to ur body wt for exercise which creates more effect on body n if u recover tht effect with correct nutrition u can achieve great results Free wts means using your own body wt for exercises.. Generally for begineers or people who have never exercised Also freewt machines are dumbell barbell kettlebells etc which u can start adding once u know techniques read less

The choice depends on the pathway of the exercise. Exercises have two pathways: straight and circular. All straight-line movements that are compound should preferably be done using free weights. Using free weights will ensure that the line of movement matches the line of gravity (resistance) and hence the target muscle remains under continuous tension. Using free weights also forces us to form our own pathway. This activates the core muscles as well as the other stabiliser muscles of the body and helps develop functional strength. If such exercises are done using machines, although the target muscle will remain under continuous tension due to the design of the machine, it will not help in developing functional strength as machines have a pre-defined pathway and the user is often supported. The pathway of all circular movements that are isolation movements goes in and out of the line of gravity. When such movements are done using free weights, the target muscle does not remain under continuous tension because the line of movement that is circular does not match the line of gravity that is straight. When such movements are done using cam-based machines, the muscle remains under continuous tension. The design of a cam-based machine makes sure that the muscle remains under continuous tension. The handle that the user pulls is part of a swing arm. When the user pulls the swing arm, the swing arm in turn rotates the cam around the same fulcrum. This in turn pulls a cable. The cable passes through a series of pulleys and is finally attached to a weight stack. The weight stack is pulled up in the line of gravity with the help of two guide rods. Thus, despite the user performing a circular movement, the weight is pulled in a straight line. Since circular isolation movements are non-functional, using free weights for such movements will not develop functional strength. read less
