What type of resistance is characterized by dynamic resistance using free weights?

The correct answer is characterized by the fact that dynamic resistance using free weights involves maintaining a consistent level of resistance throughout the range of motion. With constant resistance, the load remains the same regardless of the position of the body during the exercise. This is typical with free weights, as the weight does not change, providing a consistent challenge to the muscles throughout the entire movement.

In contrast, variable resistance involves devices that alter the resistance based on the position in the exercise, such as resistance machines that modify the load as the joint angle changes. Elastic resistance uses bands or cords that provide different levels of resistance depending on how far they are stretched, while cable resistance refers to using cables and pulleys, often found in gym machines, which can also alter resistance based on movement position and angle.

Thus, understanding that free weights deliver a steady and unchanging load helps clarify why constant resistance is the correct answer.
