A Tri-Set System in resistance training is defined by performing three different exercises in sequence without resting in between. This method allows for targeting specific muscle groups or different movement patterns, which can enhance muscle endurance, time efficiency during workouts, and overall training intensity. By incorporating three distinct exercises, individuals can engage multiple muscle groups and create a more varied workout routine, which can also lead to improved muscle hypertrophy and strength gains over time.

The other options do not accurately capture the definition of a Tri-Set. While alternating between strength and cardiovascular exercises is a valid training approach, it doesn't align with the tri-set concept. Completing three sets of the same exercise refers to a typical set structure rather than a tri-set system, which emphasizes variety through different movements. Lastly, doing three repetitions of one exercise focuses on the number of reps rather than the sequence of multiple exercises, which is key to effective tri-set training.
