What type of exercise involves a constant resistance moved through a joint's full range of motion?

The correct answer is associated with exercise that maintains a consistent level of resistance throughout the entire movement. Fixed resistance exercises utilize weights or machines set to a specific resistance level, which allows individuals to perform movements through a joint's complete range of motion without altering the resistance.

This type of exercise is beneficial for building strength as it provides a controlled environment, enabling the individual to focus on form and muscular engagement. By moving through the full range, it promotes joint flexibility and enhances muscular performance, making it an effective strength training method.

In contrast, dynamic training can involve varying levels of resistance and focuses more on the movement rather than maintaining a constant resistance. Circuit training combines various exercises targeting different muscle groups and typically involves lower weights and higher repetitions, thus not conforming to the definition of fixed resistance. Cardio exercises are typically aerobic in nature and do not focus on resistance but rather on increasing heart rate and endurance.
