Machines vs. Free Weights
In the quest to get bigger, faster, stronger and leaner, lifters turn to resistance training to get them to their goals. Providing resistance against movements can be accomplished in many ways. Isometric movements are where the body part is holding still against a force. Isotonic movements are where the body part is moving against the force. The overall goal for resistance training is to gradually and progressively overload the musculoskeletal system so it gets stronger.
